I had originally planned making a weather team building article, explaining how to build a team for every kind of weather, but with the new articles popping up, there is no point of it anymore, and I had something written down already, so not letting it go to waste.

-----------------------

Introduction


Sunny Day seems almost forgotten in DPP, mostly due to the major abundance of Hail, Rain, and Sandstorm teams in DPP. Just like Rain Dance, Sunny Day lacks a Pokemon that upon entering battle summons Sunny Day in OU and UU, just like Tyranitar and Abomasnow do for both Sandstorm and Hail, so you will find it difficult to set-up Sunny Day at some points.

Sunny Day has potential in both in UU and OU, if used correctly of course. It is often said that Sunny Day is "not strong enough", or sometimes "not worth setting-up"; this isn't true. The simple fact that Sunny Day has the ability to boost certain Pokemon's Speed thanks to their ability makes this a strategic plan, which of course has potential. The major thing with Sun is that there are only a handful of Pokemon that can abuse it. But have no fear, this guide has been made with the best intentions of not letting go of your idea of making a successful Sunny Day team be destroyed.

With all hope, after reading this guide you may be able to build a good Sunny Day team on your own.

Getting to know Sunny Day

Like it was mentioned previously, Sunny Day can only be summoned into the field by using the move "Sunny Day". Another way you can set-up Sunny Day is by using the ability "Drought", which sadly, is only seen in Ubers by the Pokemon Groudon, who most likely will stay in Ubers in DPP.

Sunny Day raises Fire-type move's damage to increase by 50%, and Water moves to do 50% damage. Healing moves such as Moonlight and Morning Sun heal 2/3 of the user's maximum HP. It also decreases Thunder's accuracy from 70% to 50%, making Thunder a very poor option to utilize while Sunny Day is in play. Apart from only lasting 5 turns (though it lasts 8 with the use of a Heat Rock), no Pokemon can be frozen while Sunny Day is in effect, meaning Ice-type moves like Ice Beam cannot induce a freeze. The most important thing that Sunny Day causes is probably the aptitude to double the Speed of Pokémon with with the ability called "Chlorophyll", which can make them potential sweepers. Solar Power, another ability held by some Pokemon, can create much more potential and effective sweepers with this ability. Though the Pokemon lose 1/8 HP per turn, its Special Attack stat is increased by 50%.

You will probably see more Sunny Day action in UU than you will in OU, as most Pokemon who benefit from Sunny Day are UU material due to the fact that they have certain abilities such as Chlorophyll.

Sunny Day Speed

There are only a couple of handful of Pokemon that can abuse Speed Sunny Day with Chlorophyll, which will be listed here:

Bellossom - base 50
Exeggutor - base 55
Jumpluff - base 110
Shiftry - base 80
Sunflora - base 30
Tangrowth - base 50
Tropius - base 51
Victreebel - base 70
Vileplume - base 50

As you can see, their base Speed stat is rather low, but can manage to fix that with Sunny Day, which will outspeed more things in UU than it will in OU.

Sunny Day Team Building

This is the part where you will learn how to build your Sunny Day team. This part will go step-by-step telling you how to start shape up a good Sunny Day team.

The Lead

This is probably the one of the most important parts when building the Sunny Day team, because this is the Pokemon that will lead the team and attempt to set-up Sunny Day. In OU, you have the options using a lead that can use the famous "Stealth Rock" leads, which can possibly let you set-up Sunny Day as well. Most importantly, you want a Pokemon that can make use of the move U-turn if possible, so you still have a potential Pokemon that can set-up Sunny Day if needed. Whatever your lead is, it is strongly recommended that you use Heat Rock as an item on that certain Pokemon, to ensure 8 full turns of glorious Sunny Day for your team.

Sunny Day Abusers

These are the kind of Pokemon that abuse their ability, Chlorophyll, with the help of Sunny Day, making them potential sweepers. And also thanks to Sunny Day, Fire-type Pokemon's Fire-type moves are increased, which a STAB + 50% increase results into a real hurting.

Sunny Day Back-up


For this role, Pokemon that are dedicated to setting up Sunny Day go here: this includes Pokemon who have the ability Leaf Guard, which allows them invulnerability to status moves such as Thunder Wave and Will-O-Wisp.

Support

Supporting Pokemon are extremely useful when it comes to weather teams. No matter how effective your strategy is, there is always something that will bother the team. In short, this part of the team building should be used with a lot of consideration.

Strategies

Plans for Sunny Day are easy, there's nothing to them really. You will be abusing Fire-type and Grass-type Pokemon, like all Sunny Day teams should be doing, so some Leech Seed stalling isn't a bad idea. Leech Seed stall will require of Pokemon that have the ability to learn Leech Seed, which is almost all of the usable Grass-type Pokemon that have Sunny Day potential. This strategy can cause irritation to the opponent, even more with some Toxic support, you will be draining HP and apart from that the opponent will be losing HP to its status infliction caused by Toxic. You should feel safe running Toxic, as Sunny Day teams tend to have Fire-type Pokemon, which eliminate Steel-type Pokemon that thanks to that typing, are immune to Toxic, so this strategy is pretty nifty, especially if some of the things used above are used in tandem as stated previously.

You can always go all out offensive Sunny Day, which is probably the best strategy there is. If you plan on doing such, just make sure you cover big weaknesses that Sunny Day teams encounter the most, such as some Dragon-type eliminator and such. There isn't many strategies for Sunny Day out there, but you can be assured the ones listed above have effectiveness.

Sunny Day Team Checklist

It does not matter if you're playing Sunny Day in OU or UU, make sure you have most of these covered, as it is one of the keys to making a successful Sunny Day Team.
  • Have a resistance for Bulky Waters
This is probably the most important thing to consider on the checklist: have something to handle Bulky Waters. Otherwise, they can be very problematic. You won't often have this problem though, as half the Pokemon that make use of Sunny Day are Grass-types, therefore giving you a check against most Water-types. It is NOT recommended to make a Sunny Day team without a Grass-type Pokemon for this reason.
  • Have a something to handle Fire-type Pokemon and Flash Fire
Fire-type Pokemon can be somewhat of a problem if you don't pack anything against them, and more problematic is Heatran; with the ability Flash Fire, it has the ability to absorb Fire-type attacks. Heatran not only boosts its Fire-type moves by 50% thanks to Flash Fire, but also makes Grass-types that lack a Ground-type move ineffective. Timid Tangrowth and Exeggutor can both outspeed Heatran in the Sunny Day, and both will outspeed and OHKO with a Life Orb Hidden Power Ground.
  • Have enough Sunny Day
What's a Sunny Day team without the move Sunny Day? The worst case scenario that can happen is the lack of Sunny Day, or not packing enough Pokemon that can set Sunny Day up. It is suggested that you have at least 3 Pokemon that can set up Sunny Day, as you don't need the whole team to have Sunny Day in their moveslot.
  • Have a Rapid Spinner
This isn't really necessary except in a few cases. Some Pokemon, like Moltres, take 50% damage from switching into Stealth Rock.
  • Have a weather changer "counter"
Don't let Tyranitar ruin your fun now! You're probably thinking this is insane, well not really. In OU, it is clear that you cannot have everything in a team, you are limited. If its possible, carry a Steel-type Pokemon. As redundant as it sounds, Pokemon such as Fortress can be a great check for both Tyranitar and Abomasnow, while being able to Rapid Spin as well, heck, it's even able to learn Sunny Day, making it a worthwhile consideration.

There is a lot more that you can pack as well, but these are the most important when it comes down to Sunny Day team building.

Ubers

Sunny Day is an excellent concept in OU and UU. But what about Uber? With Groudon, the move is unnecessary thanks to Drought. Ubers is an interesting twist to a Sunny Day team because it requires different Pokemon to counter. Such an example is Kyogre: its monstrous Special Defense stat, Water-typing, and Drizzle ability make Sunny Day teams harder to use. Rayquaza is another threat to Sunny Day teams. Rayquaza's ability, Air Lock, nullifies all weather effects on the field. With the correct Pokemon and ample prediction, this can be handled. Keep in mind that Ubers is very unpredictable, but this shouldn't stop you at all. "Drought-abusing Teams", as we'll call it, requires the following:

- A Pokemon that can prevent Stealth Rock from being layed down.
- A Pokemon that can lay Stealth Rock for the team.
- Groudon, obviously.
- Moves that counter threats; Kyogre in particular.
- Pokemon to abuse the weather.

A good lead would be either Deoxys-S or Scarf Darkrai. The latter is the better decision, while Deoxys-S should be the next Pokemon released after Darkrai incapacitates a Pokemon with Dark Void. The combination of these two prevent Stealth Rock from being layed; whether the opponent depends on Stealth Rock being set up early or later in the match. Groudon should be considered next. The ParaDancer set is highly recommended to slow the opponent's switch ins, but other sets such as the pure Swords Dancer, Rock Polish, or Support sets work. Ho-oh becomes a very obvious Pokemon. STAB Sacred Fire is hard to shrug off, especially when its backed up with a 50% chance of inflicting a burn. A Life Orb set with a Lonely or Hasty nature is viable. Sacred Fire / Thunder / Earthquake / Roost allows Ho-oh to 2HKO 404 HP / 316 SpD Kyogre with Thunder. Roost helps Ho-oh recover from Life Orb recoil; however, Return and Punishment are options if Lati@s are of concern. Palkia is an excellent Pokemon that can work with the sun. Fire Blast and Spacial Rend offer excellent coverage backed up with Thunder to 2HKO Kyogre switch ins. Outrage should be the final attack to pummel Blissey. With a Life Orb, Palkia is doing massive damage as a mixed sweeper.

The final Pokemon is hard to choose from. Chlorophyll Pokemon such as Exeggutor, Shiftry, and Tangrowth are good options to choose from. Exeggutor has a 125 Special Attack stat, can outpace Deoxys-A with a positive Speed nature and 204 EVs placed into Speed, and explode when necessary. Shiftry is able to explode as well; however, Shiftry's second STAB is useful for damaging the influencial Psychic-types in Ubers. It's lower Special Attack stat is noticable, so using Nasty Plot to boost your Special Attack isn't a bad option. Tangrowth has the biggest movepool of the three. With access to Earthquake, Power Whip, Grass Knot, and Focus Blast, Tangrowth is a little more difficult to handle. Be aware that these Pokemon are troubled against Lati@s, Scizor, and Rayquaza.

The Pokemon you should be aware of most have been listed: Kyogre and Rayquaza. However, previously mentioned Pokemon such as Lati@s, Scizor, and Giratina cause Sunny Day teams grief without proper Pokemon. Remember when building a Sunny Day team that these Pokemon should be taken care of one way or another.

Sunny Day Pokemon

This guide will be listing Pokemon that are very helpful Pokemon in Sunny Day conditions.

Sunny Day Leads

OU:

Azelf - Just like the Rain Dance lead, Azelf makes a great Sunny Day lead. Thanks to its great Speed, it's able to set up Sunny Day very quickly, which will prevent taunt-users from taunting Azelf. Azelf has the ability to do one of the following: either U-turn and save Azelf for when you need Sunny Day, support the team by setting up both Reflect and Light Screen, or Exploding in the opponent's face, thus having having the possibility of taking down one of the opponent's Pokemon.

Uxie - The most bulky of the legendary trio, therefore being able to guarantee a Sunny Day if possible thanks to its phenomenal defenses. A lot of bulk means you have the capability of setting up Stealth Rock and Light Screen or Reflect without worrying about taking a hit. Unlike Azelf, Uxie has Yawn. Yawn is a great scouting move that forces switches, thus coming in handy as it can put a Pokemon to sleep if it decides to stay in. Trick is something Uxie can pull off as well, which possibly Trick a move such as Choice Scarf and set-up Sunny Day and possibly Stealth Rock as well.

Bronzong - Possibly a redundant Pokemon, but c'mon, seriously, when is Bronzong not a good lead for any team? Bronzong also posseses the ability to learn Sunny Day, making it an awesome lead in OU Sunny Day teams. Bronzong is one of those Pokemon that can either ensure Sunny Day to be set up, possibly for 8 turns if it has Heat Rock equipped, or faces a fast Taunt-user such as Azelf or Aerodactyl. Bronzong is a lead and support Pokemon all in one. Thanks to its amazing resistances, it's one hell of a Pokemon to take down.

Jirachi - Jirachi makes a good Sunny Day user.Like Bronzong, Jirachi is able to set up Sunny Day and has access to Stealth Rock as well, making it something to take in mind when choosing a lead. The most unique thing that Jirachi has is probably Wish, which will be able to provide healing as team support, something that is extremely helpful in every team. Jirachi makes a solid choice all around.

Moltres - This also makes a great lead as Moltres is a Fire-type while being able to set up Sunny Day. Moltres is probably the Pokemon that will be scaring off Steel-type leads who want to ruin the fun, while it's able to potentially sweep as well. You might want to have a Rapid Spin support in the team if you're thinking about using Sunny Day and U-turn in tandem, as Moltres's switch-ins are drastically limited without a Rapid Spinner, which without one Moltres will be taking 50% on the switch-in, not the best thing you want to happen.

Roserade - Roserade is a fantastic lead in OU, and its no different in Sunny Day! Being able to learn Toxic Spikes makes this Pokemon a good lead, as setting up some Toxic Spikes, or regular Spikes, is always helpful for a team to sweep. Unfortunately, it's not able to learn Stealth Rock like other leads, but it's able to learn both Weather Ball and SolarBeam. The former becomes a 100 base power Fire-type attack, the latter is a deadly attack once you consider it with STAB.

Infernape - Infernape work well as a lead, as its capable of learning both Fake Out and Stealth Rock, there is nothing stopping it from setting up Sunny Day too. Infernape has an advantage when being a lead thanks to Infernape being able to learn Close Combat, which will tear apart Tyranitar, or atleast scare it off.

UU:

Jumpluff - One of the fastest Pokemon of the UU, which it's able to learn Sunny Day as well. Jumpluff makes a great option as a lead; not only because of its stellar Speed, but its other moves, such as Sleep Powder and Stun Spore make it a great option. It has access to U-turn, which allows Jumpluff to switch safely from harm right after setting up the sun. In short, this gives Jumpluff the ability to set-up Sunny Day again if needed. Encore is another surprise move on Jumpluff, being able to get the opponent stuck in one move can allow Jumpluff to proceed and set-up Sunny Day.

Victreebel - Victreebel might not have the best Speed, but its base 70 Speed is definitely something to look out for, especially when you realize there isn't many UU Pokemon that are faster. Victreebel is the one of the best Sunny Day sweepers due to the fact that it can learn both Sword Dance and Synthesis, making it a Pokemon that can recover effectively while it sweeps.

Persian - Similair to the Rain Dance set for Persian in the analysis, it can utilize Sunny Day while supporting the team with Taunt, Hypnosis, Fake Out, and U-Turn.

Sunny Day Sweepers


OU:

Tangrowth - Tangrowth is a sturdy Pokemon; pretty much the best Grass-type when it comes to defensive capabilities. Unlike Celebi, Tangrowth does not learn Recover, but it's able to learn Synthesis and Morning Sun. Tangrowth's mixed set in the analysis is something that is hard to handle under Sunny Day conditions, so it is something to consider when using it.

Exeggutor
- Of all the Chlorophyll Pokémon, Exeggutor has the highest Special Attack, making it a pretty effective sweeper under Sunny Day. With the use of Chlorophyll, Exeggutor has the capability to reach a monster 418 Speed stat with max Speed and a neutral nature, which outspeeds Choice Scarf Heatran and others. Furthermore, Exeggutor has access to moves like SolarBeam and Stun Spore and Sleep Powder, making it a pretty effective Pokemon. It also has access to Explosion, so once Exeggutor can't go at it anymore, it can explode and possibly take down another Pokemon.

Infernape - Infernape makes a powerful sweeper all around. Being able to hit hard from both sides of the spectrum makes this Pokemon a great option, even for a Sunny Day team.Infernape's STAB Fire Blast can become more deadly under Sunny Day, as it gets a 50% boost from Sunny Day, making it Infernape's secret weapon. Infernape has the option of running Choice Band, Choice Specs, or Mixed. Mixed would be the most recommended as it has access to Grass Knot (Infernape also learns SolarBeam, which will hit heavier opponents harder than Grass Knot). Hidden Power Ice hits Dragon-types while Grass Knot prevents it from being walled by bulky waters. As for Blissey, Close Combat will eliminate her as a threat.

Entei - Entei is one of the few Fire-type Pokemon that has access to SolarBeam and Calm Mind, which makes Entei one of those Pokemon that you really want on a Sunny Day team. Entei can also hit from both sides of the spectrum, but not as hard as Infernape due to its limited physical movepool, so Entei is better off being a Choice Specs or Calm Mind-user.

Heatran - Heatran is a Pokemon with the awesome Steel and Fire-typing, making it able to handle Dragon-types to some extent and many Special Attacks that are thrown at it. Heatran makes a good use of both Choice Specs and Choice Scarf, and also has access to SolarBeam like all other Fire-type Pokemon (except for Pokemon like Flareon), making Heatran another Pokemon that will enjoy Sunny Day for the 50% boost of its Fire-type attacks.

Houndoom - Base 110 Special Attack is not bad at all. Houndoom becomes a beast when given Choice Specs, with access to SolarBeam, and the boost of its Fire Blast and thanks to Sunny Day, it can be pretty dangreous. Though its Speed can be a let down for some, its ability to counter Psychic-types such as Azelf, thanks to its part Dark-type that shouldn't be overlooked!

Magmortar - Magmortar is another great Fire-type Pokemon that should be an option for a Sunny Day, mostly because of its possible sweep with a Mixed Attacker set, something that is often overlooked. Magmortar, like Infernape, can hit hard from both sides of the spectrum, so it's capable of running both a Choice Band and a Choice Specs set, but with its access to SolarBeam, a 125 Special Attack stat, and the boost from Sunny Day, Fire Blast means danger. Magmortar does not really care about Flash Fire like other Fire-types though due to its access to Focus Blast and Cross Chop, though both of the attack's accuracy is shaky.

Typhlosion - Typhlosion is great in Sunny Day with Choice Scarf or Specs. In fact, Modest Typhlosion manages a to 2HKO (50.23% - 59.14%) with a Choice Specs Eruption under the sun, to a 651 HP / 385 SpD Blissey. Unfortunately, Stealth Rock somewhat ruins this, but still, it is great option to consider.

UU:

*Note: Although most of the useful Sunny Day sweepers are listen for UU, the following Pokemon are fully capable of performing with excellence in OU as well, with the support of Sunny Day of course.


Bellossom - Not the best sweeper under Sunny Day, but still have some effectiveness.

Shiftry - Shiftry is one of those Pokemon that can play both the role of a physical or special sweeper, though it really wants more Special Attack and Speed. Shiftry's part Dark-type means it has the ability to learn Dark Pulse, giving you a chance to eliminate things like Grumpig and Hypno without having to pack something specifically for both these Pokemon.
Tropius - Pretty much on the same page as Bellosom, not really the best sweeper under Sunny Day, but things like Sword Dance make it differ from the others, as Tropius is really one of the Pokemon that can actually work with a physical set under Sunny Day. Tropius holds the ability Solar Power, which makes its Special Attack increase incredibely. Packed with a Choice Specs, very little will be resisting this powerhouse.

Victreebel - Victreebel is one of the Pokemon that shines the most in a Sunny Day team. Victreebel is much better than Shiftry in terms of being able to attack from both sides of the spectrum, thanks to base 105 Attack and base 100 Special Attack is something that shouldn't be overlooked. It has access to Swords Dance, which makes it a pretty effective physical sweeper considering it has the ability Chlorophyll. Packed with Swords Dance, it can destroy a lot if used correctly.

Vileplume - Vileplume can be pretty annoying Pokemon under a Substitute, thanks to its part Poison-type, it handles Fighting-type Pokemon much better than the others. In offensive terms, this Pokemon does the same thing as the other Sunny Day Sweepers do, though it won't make much use of Chlorophyll thanks to its slow base Speed.

Sunflora - Its probably one of the Sunny Day sweepers with a high base Special Attack. It might not look like much, but Sunflora has access to Solar Power, which packed with a Choice Specs reaches an insane Special Attack stat. With SolarBeam and Sunny Day at hand, not much will be stopping the massive destruction this can cause.

Rapidash - Rapidash is a great Sunny Day sweeper in UU, regardless about what others say. Rapidash is the only Fire-type Pokemon that gets access to Megahorn (though its accuracy isn't the best), making it the only Fire-type Pokemon in UU who isn't walled by Hypno, Grumpig, and Claydol. Rapidash also has Hypnosis in its support movepool, It may not have the best accuracy, but its still something to look in Rapidash.

Ninetales - Ninetales absolutely loves Sunny Day. With it knowing Nasty Plot as well as access to SolarBeam, it can leave opposing teams in fear. Ninetales also gets Hypnosis, again not the best acuracy, but should be considered.

Flareon - DPP blessed Flareon with SuperPower, giving it an edge against Clefable now. Flareon is able to cause a lot of havoc with its Mixed Sweeper set, and is even more deadly in Sunny Day. Flareon might not have access to SolarBeam like the other Fire-types, but can still make use of Hidden Power Grass, so Flareon won't be fearing Water-types either.

Castform - This is probably the weakest option if you consider judging Pokemon by their stats, but under Sunny Day its attack "Weather Ball" can become somewhat lethal. Otherwise, this little guy can be used for setting up Sunny Day as well.

Wormadam - Wormadam does not have the best movepool, but its able to cause damage in UU with the use of Sunny Day, due to it being able to use SolarBeam, packed with a Choice Specs can cause quite some damage.

Support

OU:


Celebi - An extremely useful Pokemon for a Sunny Day team in the OU enviorment. Celebi will be the main Pokemon to stop things such as Swampert, Vaporeon, and Suicune from ruining your team's sweep. Celebi has access to Thunder Wave and Recover; Thunder Wave will provide some paralysis support, mostly used so you feel safer using your set-up Pokemon, such as Victreebel.

Dugtrio - One of the best revenge killers out there, and it has a reason for that. You will sometimes find Pokemon like Tyranitar ruining Sunny Day teams, but Dugtrio is here for that. Dugtrio has STAB Earthquake, which will ensure an OHKO on Tyranitar, eliminating one less thing to worry about.

Cresselia - Sunny Day teams tend to have problems with Dragon-type Pokemon in OU, mostly Salamence. Cresselia can be called the "#1 counter" to Dragon-types. With access to Reflect, Light Screen, Thunder Wave, and Ice Beam, there is little to worry about when Dragonite and Salamence are of concern. Moonlight benefits from Sunny Day, which will heal 2/3 of Cresselia's HP.

Moltres - Moltres is once again mentioned here, as it's a support Pokemon as well. Despite its horrific weakeness to Stealth Rock, Moltres makes a great counter to Fighting-types and others, and is able to set up Sunny Day as well.
Rhyperior - Rhyperior is the OU version of Camerupt, which is a pretty good option as well. Thanks to Rhyperior's awesome ability, Solid Rock, Rhyperior takes much less from Water-type moves, thus giving some more bulk to this Pokemon. Rhyperior is also able to learn Sunny Day and Stealth Rock, which also makes it a good support Pokemon.

UU:


*Note: Although most of the useful Sunny Day sweepers are listen for UU, the following Pokemon are fully capable of performing with excellence in OU as well.

Leafeon - Possibly the best bulky water eliminator for a Sunny Day team. Having the ability "Leaf Guard", it makes Leafeon heal much faster from status moves such as paralysis, making a pretty effective bulky Grass-type Pokemon. Leafeon also has access to Swords Dance, and with its amazing bulk, it's capable of causing havoc after a few Sword Dances.

Altaria - Altaria is here for opposing Fire-types that trouble Sunny Day teams; not just any regular Fire-type, but Flareon. Flareon has Flash Fire which gives Flareon a boost if it switches into a Fire-type attack. Grass moves are not very effective on it either, so it causes trouble for Sunny Day teams to bypass.

Camerupt
- Having such a great typing, decent stats, and a good support movepool make this Pokemon what it is in a Sunny Day team: fantastic. Camerupt's typing allows it to have an immunity to both Thunder Wave and Will-O-Wisp, which otherwise cripples your team's sweepers. Furthermore, its immunity to Electric-type attacks as well as its abundant resistances make Camerupt a Pokemon that not only can be utilitzed in UU, but also in OU to keep threats such as Heatran and Zapdos in check. Camerupt also has access to moves to Stealth Rocks and Yawn. Stealth Rock for team support and Yawn is for some possible scouting. Roar is also useful for scouting since it works outside of Sleep Clause. Yawn, on the other hand, becomes ineffective after the Pokemon falls asleep, so its something to consider when picking between the two.

Magcargo
- Though its typing isn't the best, it has a good handful of support moves Sunny Day teams can use. Magcargo has access to Stealth Rocks and Yawn, and it also have access to Reciver and both Light Screen and Reflect, making it something to consider.

Shuckle - Shuckle is one almighty bulky Pokemon. Shuckle is a support Pokemon mostly because of its ability to learn Sunny Day (like every other Pokemon lol) and having access to Stealth Rock, but being able to bring down things with Toxic. Shuckle also has Encore, which can be extremely annoying for the opponent.

Venusaur - Venusaur is a Pokemon that can utilize both sides of the offensive spectrum effectively. Physically, it is able to learn Swords Dance with moves such as Seed Bomb, Return, and Earthquake to back it up. Specially, Venusaur has an excellenet Special Attack stat as well as attacks such as SolarBeam, Hidden Power, and Sludge Bomb to utilize.

Hitmontop - "What the hell is it doing here?" Hitmontop will be helping out with Pokemon such as Lapras with Close Combat. As for Mantine, Stone Edge will shut it down. Hitmontop is also a nifty Rapid Spin user as well. Hitmontop also makes a check for Clefable, who can pretty much dominate a Sunny Day team if not prepared for.

Threats

Tyranitar
- Weather teams' biggest enemy: Tyranitar. It's not much the Pokemon itself, it is Tyranitar's ability. which automatically brings Sandstorm into play when this Pokemon is summoned. With it's high Special Defense thanks to sandstorm giving it a boost, Fire-types won't be doing much to its mostly because of its part Rock-type. Sandstorm also makes SolarBeam have a 1 turn charge.

Tyranitar can be brought down by Dugtrio though, and with much ease, so it's not really something you should worry about if you have a Dugtrio in your team.

Hippowdon
- This too a threat, thanks to Sandstream again, but to a lesser extent. Its a Ground-type, meaning it won't be able to handle Grass-type Pokemon at all, so something like Vileplume or Celebi should be able to handle it too much affluence.

Abomasnow
- Abomasnow is a threat as well due to its ability changing the weather. Most Sunny Day teams pack a Fire-type; however, Grass-types should be aware of the 100% accurate Blizzards when facing Abomasnow.

Vaporeon - Bulky Waters like Vaporeon will always be a threat to Sunny Day teams that don't carry a Grass-type Pokemon, but not many teams are seen without a Grass-type, so its probably not something to worry about much.

Suicune - Suicune follows the same page as Vaporeon. Calm Mind, on the other hand, makes Suicune very different from Vaporeon. After a few Calm Minds, it can cause havoc with Ice Beam and Surf. Yawn can handle most Suicune as well as Roar.

Swampert - Swampert is a real pain in the ass but Celebi handles Swampert like there is no tomorrow, and so does any other Grass-type, and again, Sunny Day teams rarely go without a Grass-type Pokemon.

Heatran - Heatran's Flash Fire is something that can that can be troublesome. Heatran makes Fire-type moves useless thanks to Flash Fire. Camerupt can switch into Heatran that aren't locked into Earth Power. It isn't the best answer to Heatran, but is reliable in doing so thanks to STAB Earthquake. Cresselia can also get some action going on, but might require to pack Calm Mind and Hidden Power Ground, which isn't really recommend to do.

Salamence - Dragon-types are also problems, as Salamence resists both Fire-moves and Grass-type moves. Dragon-type Pokemon problems can easily be eliminated by Cresselia though.

Blissey - With a monster base 255 HP and base 135 Special Defense, it can be an unpleasant Pokemon to fight with a Sunny Day team due to the fact that most of Sunny Day teams are composed of the special side of the spectrum. Dugtrio can possibly 2HKO Blissey while Infernape can handle Blissey with Close Combat. With the proper Pokemon, this shouldn't be an issue.

UU:

Quagsire
- This also goes under the bulky water type category. Grass-type Sunny Day Pokemon will handle it.

Gatrodon - See above.

Lanturn - Lanturn resists Fire-type moves, and Grass-type moves to some extent, though Lanturn won't be taking Choice Specs SolarBeams well.

Lapras
- Lapras isn't much of a threat, mostly because of its weakness to Stealth Rock, but still something to look out for.

Golduck - Golduck is probably the Water-type you should look out for the most, as its Cloud Nine ability nullifies Sunny Day, but Golduck is be dominated by Grass-types. Golduck can see some action in OU as well, as its ability allows for Sunny Day to have no effect as long as Golduck is in play, making Fire Blast from Pokemon like Heatran somewhat weaker.

Mantine - Mantine is probably a problem that's hard to counter. Mantine also has a horrible weakness to Stealth Rock, so your best bet is to have Stealth Rock in play and either Yawn or Roar.

Clefable - With its base 90 Special Defense and base 95 HP, it can be a potent thread that can shrug off Special Attacks with ease, but can be defeated by Sunny Day Swords Dance sweepers such as Leafeon and Tropius. The easy way out would be using Hitmontop.


Conclusion

Hopefully, you at least got an understanding about how Sunny Day teams work. Since you know what it's supposed to be composed of, now it's time for you to put yourself to the test and make your own Sunny Day team. Whether it is OU or UU, you can hopefully make a good Sunny Day team: just don't forget there is no such thing as "too much Sunny Day"!"

Don't almost all Sunny Day teams carry a Grass type Pokemon? The lines with "if you don't have a Grass type" don't see to make sense to me. I've never made nor seen a Sunny Day team that lacked a Grass type. Maybe just tweak the phrasing there.

I just skimmed this and I'll look over it more later but it looks pretty good so far.

This is a really comprehensive article; however shouldn't Cherrim be mentioned in the "Getting to know Sunny Day" section? Flower Gift boosts its Atk and SpDef 50%. Probably much more useful in 2v2 but worth a mention nonetheless...

Don't almost all Sunny Day teams carry a Grass type Pokemon? The lines with "if you don't have a Grass type" don't see to make sense to me. I've never made nor seen a Sunny Day team that lacked a Grass type. Maybe just tweak the phrasing there.

allright

I'm surprised at the lack of mention in detail of other fire types who welcome the extra 50% damage increase granted due to Sunny Day. Entei, Houndoom, Typhlosion, and so on, even lesser used things like Rapidash and Ninetales who can also use Hypnosis, all love the sun. In fact, the majority of Fire-types can also learn Solarbeam, giving them an additional weapon to play with.

Rhyperior is definately worth a mention here. Sunny day boosts it's fire punch and lowers the water weakness, plus it gives you a check against heatran.
 
#8
Toothache brought up the thing I wanted to say; sweeping Fire-types. Typhlosion is great in Sunny Day with Choice Scarf, or Specs. In fact, Modest Typhlosion manages a huge 50.23% - 59.14% with a Choice Specs Eruption under the sun, to a 651 HP / 385 SpD Blissey. Unfortunately, Stealth Rock somewhat ruins this, but still, it is great. Fire-types are superb in the sun.

On top of this, the "Have a something to handle Fire-type Pokemon and Flash Fire" might deserve a mention of Hidden Power Ground. Timid Tangrowth / Exeggutor can both outspeed Heatran in the sun, and both will outspeed and OHKO with a Life Orb Hidden Power Ground. Hidden Power Ground is great to deal with those Fire-types, trying to grab a boost. :toast:

I never said I was done with this, I'll still be adding more sweepers and threat to their respective list, mostly what Toothache said will be added

I had originally planned making a weather team building article, explaining how to build a team for every kind of weather, but with the new articles popping up, there is no point of it anymore, and I had something written down already, so not letting it go to waste.

Guide made by Venom

-----------------------
Introduction

Sunny Day seems almost forgotten in DPP, mostly due to the major of abundance of Hail, Rain, and Sandstorm teams in DPP. Just like Rain Dance, Sunny Day lacks a Pokemon that upon entering battle summons Sunny Day, just like Tyranitar and Abomasnow do for both Sandstorm and Hail, so you will find it difficult to set-up Sunny Day at some points. underlined part is awakard.

Sunny Day has potential in both in UU and OU, if used correctly of course. It is often said that Sunny Day is the "not strong enough", or sometimes "not worth setting-up", this isn't true. The simple fact that Sunny Day has the ability to boost certain Pokemon's Speed thanks to their ability makes this a strategic plan, which has potential of course. The major thing with Sun is that you will often find it hard to find useful Pokemon that abuse the Sun, but no fear, this guide has been made with the best intentions, of not letting go your idea of making a successful Sunny Day team be destroyed, because if I could, so can you.

With all hope, after reading this guide you may be able to build a good Sunny Day team on your own.

Getting to know Sunny Day

Like it was mentioned previously, Sunny Day can only be summoned into the field by using the move "Sunny Day". Another way you can set-up Sunny Day is by using the ability "Drought", which sadly, is only seen in Ubers by the Pokemon Groudon, who most likely will stay in Ubers in DPP.


Sunny Day raises Fire-type move's damage to increase by 50%, and Water moves to do 50% less damage. Healing moves such as Moonlight and Morning Sun heal 2/3 of the user's maximum HP. It also decreases Thunder's accuracy from 70% to 50%, making Thunder a very poor option to utilize while Sunny Day is in play. Apart from only lasting 5 turns (though it lasts 8 with the use of a Heat Rock), no Pokemon can be frozen while Sunny Day is in effect, meaning Ice-type moves like Ice Beam cannot induce a freeze. The most important thing that Sunny Day causes is probably the aptitude to double the Speed of Pokémon with with the ability called "Chlorophyll", which can make them potential sweepers. Solar Power, another kind of ability held by some Pokemon, can become much more potential and effective sweepers with this ability, though the Pokemon loses 1/8 HP per turn, but its Special Attack increased by 50%, making it something to consider.​


You will probably see Sunny Day being most effective in UU, as most Pokemon who benefit from Sunny Day are UU material, things that have certain abilites, such as Chlorophyll.

Sunny Day Speed

There are only a couple of handful of Pokemon that can abuse Speed Sunny Day with Chlorophyll, which will be listed here:

Bellossom - base 50
Exeggutor - base 55
Jumpluff - base 110
Shiftry - base 80
Sunflora - base 30
Tangrowth - base 50
Tropius - base 51
Victreebel - base 70
Vileplume - base 50

As you can see, even though most oftheir base Speed (deleted) is rather low, you can fix that with Sunny Day. Even after a Sunny Day Boost though, they aren't as fast as many fast Choice Scarfers, so these Pokemon will outspeed more things and therefore be more effective in UU than they will in OU.

Sunny Day Team Building

This is the part where you will learn how to build your Sunny Day team. This part will go step-by-step telling you how to start shape up a good Sunny Day team.

The Lead

This is probably the one of the most important parts when building the Sunny Day team, because this is the Pokemon that will lead the team and attempt to set-up Sunny Day. In OU, you have the options using a lead that can use the famous "Sucuide" leads, which can be utilized to allow you set-up Sunny Day as well. U-turn is an extremely important and valuble move to have on a Sunny Day user, so you still can set-up Sunny Day later in the match if needed. (deleted) Having your lead hold Heat Rock is perhaps the most important thing to ensure 8 full turns of glorious Sunny Day for your team.

Sunny Day Abusers

This are the kind of Pokemon that abuse their ability, Chlorophyll, with the help of Sunny Day, making them potential sweepers. And also thanks to Sunny Day, Fire-type Pokemon's Fire-type moves are increased, which a STAB + 50% increase = real hurting.

Sunny Day Back-up

In this part, Pokemon that are dedicated to setting up Sunny Day go here, this Pokemon include Pokemon who have the ability Leaf Guard, which makes them invulnerable to status moves, making them good Pokemon that you can bring out to a move such as Thunder Wave and Will-O-Wisp.

Support

Supporting Pokemon are extremely useful when it comes to weather teams, no matter how effective your strategy is, there is always something that can stop it, so this part of the team building should be used with a lot of wisdom.
Sunny Day Team Checklist

It does not matter if you're playing Sunny Day in OU or UU, make sure you have most of these covered, as it is one of the keys to making a successful Sunny Day Team.
  • Have a resistance for Bulky Waters
Having something to handle Bulky Waters should be consider a priority for your team, otherwise they can be very problematic. You won't often have this problems though, as half the Pokemon that best make use of Sunny Day are Grass-type Pokemon, therefore giving you a check against Bulky Waters. (deleted, didn't really fit)
  • Have a something to handle Fire-type Pokemon and Flash Fire
Fire-type Pokemon can be somewhat of a problem if you don't pack anything against them, and even more problematic is Heatran, with Flash Fire allowing it to power up its Fire Moves by 50%. Grass-types don't often do well against Heatran either, making it even more of a threat. Timid Tangrowth and Exeggutor can both outspeed Choice Scarf Heatran in the Sunny Day, (deleted, repetition) and OHKO with a Life Orb Hidden Power Ground.
  • Have enough Sunny Day
What's a Sunny Day team without any Sunny Day? The worst case scenario that can happen is running out of Sunny Day, or not packing enough Pokemon that can set Sunny Day up. It is suggested that you have at least 3 Pokemon that can set up Sunny Day so your entire team doesn't fall apart.
  • Have a Rapid Spinner
This is not really necessary if you're not worried about this, but it is necessary for some Pokemon, like Moltres that take 50% from Stealth Rock on the switch-in from Stealth Rocks, which isn't a very good (deleted). Many other Fire-types that benefit from Sunny Day are weak to Stealth Rock as well, so having a Spinner will allow them to live longer and sweep better.
  • Have a weather changer "counter"
Don't let Tyranitar ruin your fun now! (deleted, too colloquial). In OU, it is clear that you cannot have everything on your team; you are limited by the sheer number of threats you may have to counter. But, if its possible, carry a Steel-type Pokemon. As odd as it sounds, Pokemon such as Forretress can be a great check for both Tyranitar and Abomasnow, while being able to Rapid Spin as well. Heck, its even able to learn Sunny Day, so it is something to consider.

There is a lot more things that can you pack as well, but these are the most important when it comes down to Sunny Day team building.

Sunny Day Pokemon

Here I will be listing Pokemon that should and are very helpful Pokemon in a Sunny Day.

Sunny Day Leads


OU:


Azelf - Just like as a Rain Dance lead, Azelf also makes a great Sunny Day lead, being able to learn Sunny Day, and thanks to its great Speed, itis able to set-up Sunny Day very quickly, preventing Taunters from Taunting Azelf. Azelf has the ability to either U-turn and save itself for when you need Sunny Day later, support the team by setting up both Reflect and Light Screen, or Exploding in the opponents face, having the possibility of taking down one of the opponents Pokemon.

Uxie - The most bulky of the legendary trio, is usually able to guarantee a Sunny Day (deleted), thanks to its phenomenal defenses. (deleted) You have the capability of setting up Stealth Rocks and Light Screen or Reflect without much worrying about being KOed too easily. Unlike Azelf, Uxie has Yawn, a great scouting move, is a move which forces switches, which can come in handy as it can sleep a Pokemon as well. Trick is something Uxie can pull off well; Trick a item such as Choice Scarf and set-up Sunny Day and possibly Stealth Rocks as well.

Bronzong - Possibly a redundant Pokemon, but (deleted, too informal) when is Bronzong not a good lead to any team? Bronzong also posseses the ability to learn Sunny Day, making an awesome lead in OU Sunny Day teams. Bronzong is one of those Pokemon who can also ensure a set-up Sunny Day- for 8 turns if it has Heat Rock equipped. It can often a fast Taunter, such as Azelf or Aerodactyl with Gyro Ball. Bronzong is a great lead and support Pokemon in one, and thanks to its amazing resistances, its one of a hell Pokemon to take down.

Jirachi - Jirachi makes a good Sunny Day'er, like Bronzong, its able to set up Sunny Day and has access to Stealth Rocks as well, making it something to take in mind when choosing a lead. The most unique thing that Jirachi has is probably Wish, which will be able to provide healing as team support, something that is extremely helpful in every team. Jirachi makes a solid choice all around.

Moltres - This also makes a great lead, being a Fire-type, and being able to set up Sunny Day. Moltres is probably the Pokemon that will be scaring off Steel-type leads who want to ruin the fun, while its able to potentially sweep as well. You might want to have a Rapid Spinner in the team if you're thinking about using Sunny Day and U-turn in tandem, as Moltres's switch-ins are drastically limited without a Rapid Spinner, which without one Moltres will be taking 50% on the switch-in, not the best thing you want to happen.

UU:

Jumpluff - One of the fastest Pokemon of the UU, which is able to learn Sunny Day as well. Jumpluff makes a great option as lead, not only because of its stellar Speed, but its other moves, such as Sleep Powder and Stun Powder make it a great option as a lead. Its access to U-turn, which allows you to U-turn safely from harm right after you set up the sun, allowing you to save Jumpluff to set-up Sunny Day again if needed.

Victreebel - Victreebel might not have the best Speed, but its base 70 Speed is defenatly something to look out for, especially when you realize there isn't many UU Pokemon that are faster.

Persian - Just like the Rain Dance set for Persian in the analysis, you can change it around by taking out Rain Dance and putting Sunny Day instead, and now you have a "Sunny Day Persian", pretty cheap but effective.

Sunny Day Sweepers

OU:

Tangrowth - Tangrowth is a pretty sturdy Pokemon, pretty much of the best Grass-types when it comes to defensive capabilites. Unlike Celebi, Tangrowths only recovery move is Morning Sun, which in Sunny Day Tangrowth recovers 2/3 of its HP.

Exeggutor - Of all the Chlorophyll Pokémon, Exeggutor has the highest Special Attack, making it a pretty effective sweeper under Sunny Day. With the use of Chlorophyll, Exeggutor has the capability to reach a monster 418 Speed stat, which outspeeds Choice Scarf Heatran and others. Furthermore, Exeggutor has access to moves like SolarBeam and Stun Powder, making it a pretty effective Pokemon, and also has access to Explosion, so once Exeggutor can't go at it anymore, it can explode and possibly take down one Pokemon.

Infernape - Infernape makes a hard sweeper all around, being able to hit hard from both sides of the spectrum makes this Pokemon a great option, even for a Sunny Day team. Infernape's STAB Fire Blast can become even more deadly under Sunny Day, as it gets a 50% boost from Sunny Day, making it Infernape's secret weapon. Infernape has the option of running Choice Band, Choice Specs, or Mixed, Mixed would be the most recommended as it has access to Grass Knot, and hits hard with Hidden Power Ice, giving you a check against Dragon-types, while Grass Knot prevents it from being walled by bulky waters, and Close Combat hits things like Blissey hard. You can also run Choice Scarf, which can pack Sunny Day and U-turn, Close Combat, and Fire Blast, making it a amazing sweeper, while being fast enough to set-up a Sunny Day or U-turn.

Entei - Entei is one of the few Fire-type Pokemon that has access to SolarBeam and Calm Mind, which makes Entei one of those Pokemon that you really want on a Sunny Day team. Entei can also hit from both sides of the spectrum, but not as hard as Infernape, due to its low base Attack and limited physical movepool, so Entei is better off being a Choice Specs Entei or Calm Mind Entei, it has SolarBeam, which benefits a lot in Sunny Day.

Heatran - Heatran is that Pokemon with that awesome typing, Steel-type and Fire-type, making it be able to handle Dragon-types to some extent, and gives it the ability to handle many Special Attacks that are thrown at it. Heatran makes a good use of both Choice Specs and Choice Scarf, and also has access to SolarBeam, like all other Fire-type Pokemon, making Heatran another Pokemon that will enjoy Sunny Day for the 50% boost of its Fire-type attacks.

Houndoom - Base 110 Special Attack is not bad at all. Houndoom becomes a beast when given Choice Specs, with access to SolarBeam, and the boost of its Fire Blast thanks to Sunny Day, it can be pretty dangreous. Though its Speed can be a let down for some, its ability to counter Psychic-types such as Azelf, thanks to its part Dark-type shouldn't be overlooked!

Magmortar - Magmortar is is another great Fire-type Pokemon that should be an option for a Sunny Day, mostly because of its possible sweep with a Mixed Attacker set, something that is often overlooked. Magmortar, like Infernape, can hit hard from both sides of the spectrum, so its capable of running both a Choice Band and a Choice Specs set, but with its access to SolarBeam, and its 125 Special Attack, plus the boost from Sunny Day, Fire Blast means danger. Magmortar does not really care of Flash Fire like other Fire-types though, due to its access to Focus Blast and Cross Chop, though Cross Chop's accuracy can be a bit shaky.

Typhlosion - Typhlosion is great in Sunny Day with Choice Scarf, or Specs. In fact, Modest Typhlosion manages a to 2HKO (50.23% - 59.14%) with a Choice Specs Eruption under the sun, to a 651 HP / 385 SpD Blissey. Unfortunately, Stealth Rock somewhat ruins this, but still, it is great option to consider.

UU:

*Note: Although most of the useful Sunny Day sweepers are listen for UU, the following Pokemon are fully capable of performing with excellence in OU as well, with the support of Sunny Day of course.

Bellossom - Not the best sweeper under Sunny Day, but still have some effectiveness.


Shiftry - Shiftry is one of those Pokemon that can play both the role of a physical or special sweeper, though it really wants more Special Attack and Speed. Shiftry's part Dark-type means it has the ability to learn Dark Pulse, giving you a chance to eliminate things like Grumpig and Hypno without having to pack something specifically for both these Pokemon.​



Tropius - Pretty much on the same page as Bellosom, not really the best sweeper under Sunny Day, but things like Sword Dance make it differ from the others, as Tropius is really one of the Pokemon that can actually work a physical set under Sunny Day. Tropius holds the ability Solar Power, which makes its Special Attack increase well, incredibely, packed with a Choice Specs, very little will be resisting this powerhouse.

Victreebel - Victreebel is probably one of the Pokemon that most shines in a Sunny Day team. Victreebel is a much better Shiftry in terms of being able to attack from both sides of the spectrum, base 105 Attack and base 100 Special Attack is something that shouldn't be overlooked. It has access to Swords Dance, which makes it a pretty effective physical sweeper considering it has the ability Chlorophyll, packed with Swords Dance can mean it can destroy a lot if used correctly.

Vileplume - Vileplume can be pretty annoying Pokemon under a Substitute, thanks to its part Poison-type, it handles Fighting-type Pokemon much better than the others. In offensive terms, this Pokemon does the same thing as the other Sunny Day Sweepers do, though it won't make much use of Chlorophyll thanks to its slow base Speed.

Sunflora - Its probably one of the Sunny Day sweepers with a high base Special Attack. It might not look like much, but Sunflora has access to Solar Power, which packed with a Choice Specs reaches an insane Special Attack stat, with SolarBeam and Sunny Day at hand, not much will be stopping the massive destruction this can cause.

Rapidash - Rapidash is a great Sunny Day sweeper in UU, regardless about what they say. Rapidash is the only Fire-type Pokemon that gets access to Megahorn (though its accuracy isn't the best), making it the only Fire-type Pokemon in UU who won't get walled by Hypno and Grumpig, and Claydol as well. Rapidash also has Hypnosis in its support movepool, but not have the best accuracy, but its still something to look in Rapidash.

Ninetails - Ninetails, the terrorific Fire-type Pokemon of UU. Ninetails absolutely loves Sunny Day, with it knowing Nasty Plot, access to SolarBeam, Ninetails can leave opposing teams in fear. Ninetails also gets Hypnosis, again not the best acuracy, but should be considered.

Flareon - DPP blessed Flareon with SuperPower, giving it edge against Clefable now. Flareon is able to cause a lot of havoc with its Mixed Sweeper set, and is even more deadly in Sunny Day. Flareon might not have access to SolarBeam like the other Fire-types, but can still make use of Hidden Power Grass, so Flareon won't be fearing Water-types either.

Support

OU:

Celebi - An extremely useful Pokemon for a Sunny Day team in the OU. Celebi will be the Pokemon that will be stopping things like Swampert from stopping your Sunny Day in its tracks, and furthermore, it will also be stopping Pokemon like Vaporeon and Suicune as well, go can be come very annoying for Sunny Day teams. Celebi has access to Thunder Wave and Recover, Thunder Wave will provide some paralysis support, mostly used so you feel safer using your set-up Pokemon, such as Victreebel.

Dugtrio - One of the best revenge killers out there, and it has a reason for that. You will sometimes find Pokemon like Tyranitar ruining Sunny Day teams, but Dugtrio is here for that. Dugtrio has STAB Earthquake, which will ensure an OHKO on Tyranitar, eliminating and becoming one less thing to worry about.

Cresselia - Sunny Day teams tend to have problems Dragon-type Pokemon in OU, mostly Salamence. Cresselia can be called the "#1 counter" to Dragon-types, as it can handle Dragon-type Pokemon with great effectiveness, and having Cresselia in your team will make you feel more confident when facing Pokemon such as Salamence and Dragonite.

Moltres - Moltres is once again mentioned here, as its a support Pokemon as well. Despite its horrific weakeness to Stealth Rocks, Moltres makes a great counter to Fighting-types and others, and is able to set up Sunny Day as well.

Rhyperior - Rhyperior is the OU version of Camerupt, which is a pretty good option as well. Thanks to Rhyperior's awesome ability, Solid Rock, Rhyperior takes much less from Water-type moves, giving some more bulk to this Pokemon. Rhyperior is also able to learn Sunny Day, Stealth Rocks, which also makes it a good support Pokemon.

UU:

*Note: Although most of the useful Sunny Day sweepers are listen for UU, the following Pokemon are fully capable of performing with excellence in OU as well.

Leafeon - Possibly the best bulky water eliminator for a Sunny Day team. Having the ability "Leaf Guard", it makes Leafeon heal much faster from status moves such as paralysis, making a pretty effective bulky Grass-type Pokemon. Leafeon also has access to Swords Dance, and with its amazing bulk, its capable of causing havoc after a few Sword Dances.

Altaria - Altaria is here for opposing Fire-types that trouble Sunny Day teams, not just any regular Fire-types, but Fire-types such as Flareon, who have Flash Fire, making Grass-type moves and Fire-type moves have no effect whatsoever on Flareon, and Altaria is one of the best counters to Flareon, so Altaria is one of those Pokemon one should really consider when making a Sunny Day team.

Camerupt - Having such a great typing, decent stats, and a good support movepool make this Pokemon what it is in a Sunny Day team, fantastic. Camerupts typing allows it to have immunity to both Thunder Wave and Will-O-Wisp, and also have immunity to Electric, this combined works amazingly in UU, and furthermore, it is totally a Pokemon that works in OU Sunny Day teams, to keep things like Heatran and Zapdos on check. Camerupt also has access to moves to Stealth Rocks and Yawn, Stealth Rocks for team support and Yawn for some possible scouting.

Magcargo - Though its typing isn't the best, but it has a good handful of support moves Sunny Day teams can use. Magcargo has access to Stealth Rocks and Yawn, making it a pretty much inferior Camerupt.

Shuckle - Shuckle is one almighty bulky Pokemon. Shuckle is a support Pokemon mostly because of its ability to learn Sunny Day (like every other Pokemon lol) and having access to Stealth Rock, but being able to bring down things with Toxic. Shuckle also has Encore, which can be extremely annoying for the opponent.

Venusaur - Venusaur is a extraordinarily Grass-type Pokemon, with some amazing defenses, this Pokemon is capable of handling things such as Hitmonlee, while it has the ability to learn Swords Dance, making it a pokemon that can be both defensive and offensive and be good at either one.

Hitmontop - "What the hell is it doing here?" Hitmontop will be helping out here with Pokemon such as Lapras, as it has access to Stone Edge, and Mantine as well, while being a pretty nifty Rapid Spinner as well. Hitmontop also makes a check for Clefable, who can pretty much dominate a Sunny Day team if not prepared for.

Threats

Tyranitar - Weather teams' biggest enemy, Tyranitar. Its not much the Pokemon itself, its its ability, Sandstream, which automatically brings Sandstorm into play when this Pokemon is summoned. With its high Special Defense, Fire-types won't be doing much to it, mostly because of its part Rock-type.

Tyranitar can be brought down by Dugtrio though, and with much ease, so its not really something you should worry about if you have a Dugtrio in your team

Hippowdon - This is too a threat, thanks to Sandstream again, but to a lesser extent. Its a Ground-type, meaning it won't be able to handle Grass-type Pokemon at all, so something like Vileplume or Celebi should be able to handle it much affluence.

Abomasnow - Abomasnow is a threat as well, due to its ability of changing the weather, but Sunny Day teams can handle Abomasnow well, as Sunny Day mostly packs Fire-type Pokemon.
Blissey -

Vaporeon - Bulky Waters like Vaporeon will always be a threat to Sunny Day teams that don't carry a Grass-type Pokemon, but not many teams are seen without a Grass-type, so its probably not something to worry about much.

Suicune - Suicune goes on the same page as Vaporeon, which Calm Mind variants are probably more threatening, as after a few Calm Minds it will be causing havoc with Ice Beam and Surf, but Yawn can handle it, as well as Roar.

Swampert - Swampert is a real pain in the ass, but Celebi handles Swampert like there is no tomorrow, and so does any other Grass-type, and again, Sunny Day teams rarely go without a Grass-type Pokemon.

Heatran - Heatran's Flash Fire is something that can trouble a lot, as it makes Fire-type moves useless, and Grass-type moves won't even scratch Heatran. Camerupt can handle Heatran, not the best answer, but is pretty reliable. Cresselia can also get some action going on, but might require to pack Calm Mind and Hidden Power Ground, which isn't really recommend to do.

Salamence - Dragon-types are also problems, as Salamence resists both Fire-moves and Grass-type moves. Dragon-type Pokemon problems can easily be eliminated by Cresselia though.

Blissey - With a monster base 255 HP and base 135 Special Defense, it can be an unpleasant Pokemon to fight with a Sunny Day team, due to the fact that most of Sunny Day Teams are composed of the special side of the spectrum. Dugtrio can revenge kill it, though it can be a possible 2HKO, and Infernape has Close Combat, so its not really something to break a sweat about with the proper Pokemon.

UU:

Quagsire - This also goes under the bulky water type category, Grass-type Sunny Day Pokemon will handle it.

Gatrodon - See above.

Lanturn - Lanturn resists Fire-type moves, and Grass-type moves to some extent, though Lanturn won't be taking Choice Specs SolarBeams well.

Lapras - Lapras isn't much of a threat, mostly because of its weakness to Stealth Rocks, but still something to look out for.

Golduck - Golduck is probably the Water-type you should look out for the most, as its Cloud Nine ability will nullifies Sunny Day, but Golduck is be dominated by Grass-types.

Mantine - Mantine is probably a problem that's hard to counter. Mantine also has a horrible weakness to Stealth Rocks, so your best bet is to have Stealth Rocks in play and either Yawn or Roar.

Clefable - With its base 90 Special Defense and base 95 HP, it can be a potent thread that can shrugg off Special Attacks with ease, but can be defeated by Sunny Day Sword Dance sweepers, such as Leafeon and Tropius, and the easy way out would be using Hitmontop.
I commented in Green. I didn't get all the way through, i'll add more tomorrow.

Would Castform be a good addition? It has the movepool to deal with Water and Grass Pokémon, although its stats are somewhat bad.

Actually, it obtains Synthesis via Platinum Move tutors (and is legal with Leech Seed btw).

Also, the MixGrowth set that is in the Platinum Peer Edit is actually quite a threat to handle. It is, by far, one of Tangrowth's best offensive set that it has to offer.

Castform, like said on the analysis, is kind of a pure novelty Pokemon, I did consider him at first, but I don't think its going to pull off anything in a Sunny Day team, or any other kind of team.

Actually, it obtains Synthesis via Platinum Move tutors (and is legal with Leech Seed btw).

Also, the MixGrowth set that is in the Platinum Peer Edit is actually quite a threat to handle. It is, by far, one of Tangrowth's best offensive set that it has to offer.
I'll add a mention

This is a really good guide and I have some suggestions for it.

In your Roserade description, you could mention the 100 BP Fire Weather Ball it has access to (meaning there is no need for HP Fire, and it can use a different type of HP).

Venom said:
Tangrowths only recovery move is Morning Sun, which in Sunny Day Tangrowth recovers 2/3 of its HP.
Nothing major, but Tangrowth learns Synthesis via Plat tutor, so get rid of the bit about it being its only recovery move.

Venom said:
nfernape has the option of running Choice Band, Choice Specs, or Mixed, Mixed would be the most recommended as it has access to Grass Knot
You mention Infernape being able to use Grass Knot, but you don't say that it has access to SolarBeam, which always outdamages (or equals) Grass Knot.

Venom said:
due to its access to Focus Blast and Cross Chop, though Cross Chop's accuracy can be a bit shaky.
This is a bit weird, seeing as Focus Blast's accuracy is even worse than Cross Chop's. You might want to say that both their accuracies are shaky, because otherwise it is a bit ironic.

That's about all. Like I said, nice guide.

I had originally planned making a weather team building article, explaining how to build a team for every kind of weather, but with the new articles popping up, there is no point of it anymore, and I had something written down already, so not letting it go to waste.

-----------------------

Introduction

Sunny Day seems almost forgotten in DPP, mostly due to the major of (remove the first "of")abundance of Hail, Rain, and Sandstorm teams in DPP. Just like Rain Dance, Sunny Day lacks a Pokemon that upon entering battle summons Sunny Day, just like Tyranitar and Abomasnow do for both Sandstorm and Hail, so you will find it difficult to set-up Sunny Day at some points. (This technically isn't true. You should say solely in OU and UU, because in Ubers Groudon has Drought).

Sunny Day has potential in both in UU and OU, if used correctly of course. It is often said that Sunny Day is the (remove "the") "not strong enough", or sometimes "not worth setting-up", (you can use a colon here between setting-up and this, however, I'd seperate if possible) this isn't true. The simple fact that Sunny Day has the ability to boost certain Pokemon's Speed thanks to their ability makes this a strategic plan, which has potential of course (Perhaps change to: "...which of course has potential). The major thing with Sun is that you will often find it hard to find useful Pokemon that abuse the Sun, but no fear, this guide has been made with the best intentions, of not letting go your idea of making a successful Sunny Day team be destroyed, because if I could, so can you.

(I'm not sure if we are to include "ourselves" in anything that involves analysis or guides. I'd do my best to avoid this. Also the last sentence seems very choppy despite the massive commas. Perhaps something like this: "The major thing with Sun is that there are only a handful of Pokemon that can abuse it. But have no fear, this guide has been made with the best intentions of not letting go of your idea of making a successful Sunny Day team be destroyed.")

With all hope, after reading this guide you may be able to build a good Sunny Day team on your own.

Getting to know Sunny Day

Like it was mentioned previously, Sunny Day can only be summoned into the field by using the move "Sunny Day". Another way you can set-up Sunny Day is by using the ability "Drought", which sadly, is only seen in Ubers by the Pokemon Groudon, who most likely will stay in Ubers in DPP.

Sunny Day raises Fire-type move's damage to increase by 50%, and Water moves to do 50% damage. Healing moves such as Moonlight and Morning Sun heal 2/3 of the user's maximum HP. It also decreases Thunder's accuracy from 70% to 50%, making Thunder a very poor option to utilize while Sunny Day is in play. Apart from only lasting 5 turns (though it lasts 8 with the use of a Heat Rock), no Pokemon can be frozen while Sunny Day is in effect, meaning Ice-type moves like Ice Beam cannot induce a freeze. The most important thing that Sunny Day causes is probably the aptitude to double the Speed of Pokémon with with the ability called "Chlorophyll", which can make them potential sweepers. Solar Power, another kind of ability held by some Pokemon, can become much more potential and effective sweepers with this ability, though the Pokemon loses 1/8 HP per turn, but its Special Attack increased by 50%, making it something to consider. (Seems awkward. Try "Solar Power, another ability held by some Pokemon, can create much more potential and effective sweepers with this ability. Though the Pokemon lose 1/8 HP per turn, its Special Attack stat is increased by 50%.)

You will probably see Sunny Day being most effective in UU, as most Pokemon who benefit from Sunny Day are UU material, things that have certain abilites, such as Chlorophyll. (Try ..."as most Pokemon who benefit from Sunny Day are UU material due to the fact that they have certain abilities such as Chlorophyll.)

Sunny Day Speed

There are only a couple of handful of Pokemon that can abuse Speed Sunny Day with Chlorophyll, which will be listed here:

Bellossom - base 50
Exeggutor - base 55
Jumpluff - base 110
Shiftry - base 80
Sunflora - base 30
Tangrowth - base 50
Tropius - base 51
Victreebel - base 70
Vileplume - base 50

As you can see, their base Speed stat is rather low, but can manage to fix that with Sunny Day, which will outspeed more things in UU than it will in OU.

Sunny Day Team Building

This is the part where you will learn how to build your Sunny Day team. This part will go step-by-step telling you how to start shape up a good Sunny Day team.

The Lead

This is probably the one of the most important parts when building the Sunny Day team, because this is the Pokemon that will lead the team and attempt to set-up Sunny Day. In OU, you have the options using a lead that can use the famous "Stealth Rock" leads, which can possibly let you set-up Sunny Day as well (Question: Suicide Lead or Stealth Rock lead, and why?). Most importantly, you want a Pokemon that can make use of the move U-turn if possible, so you still have a potential Pokemon that can set-up Sunny Day if needed (I wouldn't say U-Turn is 100% necessary, especially with Suicide leads. A good example is something such as Solrock in UU. It can set up Sunny Day, but lacks U-Turn altogether. It's more useful as a suicide lead. Now if you mean a Pokemon like Jumpluff, then I agree with you 100%). Whatever your lead is, it is strongly recommended that you use Heat Rock as an item on that certain Pokemon, to ensure 8 full turns of glorious Sunny Day for your team.

Sunny Day Abusers

This ("These") are the kind of Pokemon that abuse their ability, Chlorophyll, with the help of Sunny Day, making them potential sweepers. And also thanks to Sunny Day, Fire-type Pokemon's Fire-type moves are increased, which a STAB + 50% increase = real hurting (I'm not sure about the equal sign so this is entirely up to you. However, I'd change it to: "..."which a STAB + 50% increase results into a real hurting." But it sounds very awkward altogether, so I'd attempt to rephrase it if possible. Perhaps "These are the kind of Pokemon that abuse their ability or attacks with the help of Sunny Day. Speaking of Sunny Day, Fire-types recieve a boost in their Fire-type attacks, which is equivalent to a double STAB." Or something very similair to it.).

Sunny Day Back-up

In this part, Pokemon that are dedicated to setting up Sunny Day go here, this Pokemon include Pokemon who have the ability Leaf Guard, which makes them invulnerable to status moves, making them good Pokemon that you can bring out to a move such as Thunder Wave and Will-O-Wisp. (Seperate this into two sentences or use a colon such as this: "For this role, Pokemon that are dedicated to setting up Sunny Day go here: this includes Pokemon who have the ability Leaf Guard, which allows them invulnerability to status moves such as Thunder Wave and Will-O-Wisp.")

Support

Supporting Pokemon are extremely useful when it comes to weather teams, no matter how effective your strategy is, there is always something that bothers, so this part of the team building should be used with a lot of wisdom. (Again long-winded even with the commas. Perhaps "Supporting Pokemon are extremely useful when it comes to weather teams. No matter how effective your strategy is, there is always something that will bother the team. In short, this part of the team building should be used with a lot of wisdom.")

Strategies



Sunny Day Team Checklist

It does not matter if you're playing Sunny Day in OU or UU, make sure you have most of these covered, as it is one of the keys to making a successful Sunny Day Team.
  • Have a resistance for Bulky Waters
This is probably the thing that you should consider the most of the checklist, have something to handle Bulky Waters, otherwise they can be very problematic (Try: "This is probably the most important thing to consider on the checklist: have something to handle Bulky Waters. Otherwise, they can be very problematic."). You won't often have this problems (either "these problems" or "this problem". Probably the latter.) though, as half the Pokemon that make use of Sunny Day are Grass-type Pokemon, therefore giving you a check against Water-type Pokemon, so it is NOT recommend to make a Sunny Day team without a Grass-type Pokemon (I find this -slightly- redundant. Most Sunny Day teams have Grass-types anyway, even in OU. Also a little long-winded, so if you decide to keep it try: "You won't often have this problem though, as half the Pokemon that make use of Sunny Day are Grass-types, therefore giving you a check against most Water-types. It is NOT recommended to make a Sunny Day team without a Grass-type Pokemon for this reason.").
  • Have a something to handle Fire-type Pokemon and Flash Fire
Fire-type Pokemon can be somewhat of a problem if you don't pack anything against them, and more problematic is Heatran, (here is where a colon would be more useful IMO or start a new sentence.) with the ability of Flash Fire, it has the ability to predict Fire-type moves, which will only boost up its Fire-type moves by 50%, while Grass-types aren't doing anything to Heatran, so be on the look out for this (Rather odd structure too. Perhaps: "with the ability Flash Fire, it has the ability to absorb Fire-type attacks. Heatran not only boosts its Fire-type moves by 50% thanks to Flash Fire, but also makes Grass-types that lack a Ground-type move ineffective.") . Timid Tangrowth and Exeggutor can both outspeed Heatran in the Sunny Day, and both will outspeed and OHKO with a Life Orb Hidden Power Ground.
  • Have enough Sunny Day
Whats (either "What's or "What is") a Sunny Day team without any ("the move" might be better than "any") Sunny Day? The worst case scenario that can happen is running out ("the lack of" might sound better than "running out". Entirely up to you though.) of Sunny Day, or not packing enough Pokemon that can set Sunny Day up. It is suggested that you have at least 3 Pokemon that can set up Sunny Day, (either use a colon after "Day" or simply put "as" before "you")you don't need the whole team to have Sunny Day in their moveslot.
  • Have a Rapid Spinner
This is not really necessary if you're not worried about this, but it is necessary for some Pokemon, like Moltres that take 50% from Stealth Rock on the switch-in from Stealth Rocks, which isn't a very good thing to happen. (Double negative. Try: "This isn't really necessary except in a few cases. Some Pokemon, like Moltres, take 50% damage from switching into Stealth Rock.")
  • Have a weather changer "counter"
Don't let Tyranitar ruin your fun now! You're probably thinking this is insane, well not really. In OU, It (decapitalize "it") is clear that you cannot have everything in a team, you are limited (..."in a team as you are limited to the number of Pokemon in a team." or something similair to that). If its ("it's or "it is") possible, carry a Steel-type Pokemon. As redundant as it sounds, Pokemon such as Fortress can be a great check for both Tyranitar and Abomasnow, (the comma isn't necessary, but entirely up to you). while being able to Rapid Spin as well, heck its even able to learn Sunny Day, so something to consider (The phrase "Heck it's even able to learn Sunny Day, so something to consider" seems very awkward and really needs to be seperated into its own sentence. Perhaps: "Heck, it's even able to learn Sunny Day, making it a worthwhile consideration.").

There isa lot more things ("things" is rather unnecessary and makes the sentence sound weird. If you want to use it try: "There are a lot more things...") that can you ("you can") pack as well, but this ("these") are the most important when it comes down to Sunny Day team building.

Sunny Day Pokemon

Here I will be listing Pokemon that should and are very helpful Pokemon in a Sunny Day. (Again, I'm not sure if we are supposed to use first-person.)

Sunny Day Leads

OU:


Azelf - Just like as a ("the" over "as a") Rain Dance lead, Azelf also makes a great Sunny Day lead, being able to learn Sunny Day, and thanks to its great Speed, its able to set-up Sunny Day very quickly which will prevent Taunters from Taunting Azelf ("Just like the Rain Dance lead, Azelf makes a great Sunny Day lead. Thanks to its great Speed, it's able to set up Sunny Day very quickly, which will prevent taunt-users from taunting Azelf.)". Azelf has the ability to either (..."to do one of the following:" might be better because this is similair to a rest.) U-turn and save Azelf for when you need Sunny Day, support the team by setting up both Reflect and Light Screen, or Exploding in the opponents ("opponent's") face, ("thus having" might fit here)having the possibility of taking down one of the opponents (opponent's) Pokemon.

Uxie - The most bulky of the legendary trio, ("therefore being" fits fine here) being able to guarantee a Sunny Day if possible, (ditch the comma) thanks to its phenomenal defenses. A lot of bulk means you have the capability of setting up Stealth Rocks ("Stealth Rock") and Light Screen or Reflect without much worrying about getting hit for a lot of HP (Seems awkward. Try "...without worrying about taking a hit."). Unlike Azelf, Uxie has Yawn, a great scouting move, is a move which forces switches, which can come in handy as it can sleep a Pokemon as well (Try: "Unlike Azelf, Uxie has Yawn. Yawn is a great scouting move that forces switches, thus coming in handy as it can put a Pokemon to sleep if it decides to stay in."). Trick is something Uxie can pull off well ("as well", perhaps?), which possibly Trick a move ("...which can possibly trick an item") such as Choice Scarf and set-up Sunny Day and possibly Stealth Rocks ("Stealth Rock") as well.

Bronzong - Possibly a redundant Pokemon, but cmon (c'mon), seriously, when is Bronzong not a good lead to ("for" over "to") any team? Bronzong also posseses the ability to learn Sunny Day, making (place "it" here) an awesome lead in OU Sunny Day teams. Bronzong is one of those Pokemon who can also ensure a set-up Sunny Day, possibly 8 if it has Heat Rock equipped, or faces a fast Taunter, such as Azelf or Aerodactyl (Huh? Do you mean: "Bronzong is one of those Pokemon that can either ensure Sunny Day to be set up, possibly for 8 turns if it has Heat Rock equipped, or faces a fast Taunt-user such as Azelf or Aerodactyl."). Bronzong is probably (Probably? Bronzong is a good lead altogether, I'd remove probably) a (place "great" here) lead and support Pokemon (optional: place "all" here) in one, thanks to its amazing resistances, its one of a hell Pokemon to take down (After "one", start a new sentence. Try: "Thanks to its amazing resistances, it's one hell of a Pokemon to take down.").

Jirachi - Jirachi makes a good Sunny Day'er (Not sure about this, but "Sunny Day user" could possibly work better), like Bronzong, its able to set up Sunny Day and has access to Stealth Rocks as well, making it something to take in mind when choosing a lead (Seperate after "Sunny Day'er". "Like Bronzong, Jirachi is able to set up Sunny Day and has access to Stealth Rock as well, making it something to take in mind when choosing a lead."). The most unique thing that Jirachi has is probably Wish, which will be (replace "will be" with "is") able to provide healing as team support, something that is extremely helpful in every team. Jirachi makes a solid choice all around.

Moltres - This also makes a great lead, being a Fire-type, and being able to set up Sunny Day (It's fine, but I'd try "This also makes a great lead as Moltres is a Fire-type while being able to set up Sunny Day."). Moltres is probably the Pokemon that will be scaring off Steel-type leads who want to ruin the fun, while its ("it is" or "it's) able to potentially sweep as well. You might want to have a Rapid Spinner (I like "Rapid Spin support" better than "a Rapid Spinner" personally, but this is up to you.) in the team if you're thinking about using Sunny Day and U-turn in tandem, as Moltres's switch-ins are drastically limited without a Rapid Spinner, which without one Moltres will be taking 50% on the switch-in, not the best thing you want to happen (Seperate "Rapid Spinner" and "which". So: "Without said Rapid Spin support, Moltres's switch-ins are drastically limited, as Moltres will be taking 50% damage each time it switches in thanks to Stealth Rock.").

Roserade - Roserade, (ditch the comma and put in "is") a fantastic lead in OU, and its ("it is" or "it's) no different in Sunny Day! Being able to learn Toxic Spikes makes this Pokemon a good lead, as setting up some Toxic Spikes, or regular Spikes (because this is illegal with Sleep Powder, I'd keep this out. Up to you), is always helpful for a team to sweep, though its not able to learn Stealth Rocks like the other leads, but its Grass-type also gives it an the ability to learn SolarBeam, which is extremely deadly once you consider it with STAB (More seperation after sweep. "Unfortunately, it's not able to learn Stealth Rock like other leads, but it's able to learn both Weather Ball and SolarBeam. The former becomes a 100 base power Fire-type attack, the latter is a deadly attack once you consider it with STAB.").

UU:

Jumpluff - One of the fastest Pokemon of the UU, which is able to learn Sunny Day as well. Jumpluff makes a great option as (place "a" here) lead, (here a semicolon would work over the comma as the second statement could be a seperate sentence sort of.) not only because of its stellar Speed, but its other moves, such as Sleep Powder and Stun Powder (place a comma here) make it a great option as a lead ("as a lead" might be redundant since you've already stated that Jumpluff makes a great option as a lead. Just remove it and put a period after "option".). Its access to U-turn, which allows you to U-turn safely from harm right after you set up the sun, allowing you to save Jumpluff to set-up Sunny Day again if needed (It has access to U-turn, which allows Jumpluff to switch safely from harm right after setting up the sun. In short, this gives Jumpluff the ability to set-up Sunny Day again if needed."). (I also feel you forgot Encore, which can provide another way to set-up Sunny Day if played correctly. With Sleep Clause, Encore is the second option to act similair to it, especially if an Earthquake-user decides to be smart and simply use Stone Edge.)

Victreebel - Victreebel might not have the best Speed, but its base 70 Speed is defenatly (definitely) something to look out for, especially when you realize there isn't many UU Pokemon that are faster. (More explaination? It is probably the best Synthesis Pokemon with access to Swords Dance and Leaf Blade.)

Persian - Just like the Rain Dance set for Persian in the analysis, you can change it around by taking out Rain Dance and putting Sunny Day instead, and now you have a "Sunny Day Persian", pretty cheap but effective ("Similair to the Rain Dance set for Persian in the analysis, it can utilize Sunny Day while supporting the team with Taunt, Hypnosis, Fake Out, and U-Turn." What I wrote is optional, but try to seperate it a little more if possible.).

Sunny Day Sweepers

OU:

Tangrowth - Tangrowth is a pretty sturdy Pokemon, pretty much of the best Grass-types when it comes to defensive capabilites (Tangrowth is a sturdy Pokemon; pretty much the best Grass-type when it comes to defensive capabilities."). Unlike Celebi, Tangrowth does not learn Recover, but its ("it is" or "it's") able to learn Synthesis and Morning Sun. Tangrowth's mixed set in the analysis is also something that is hard to handle under Sunny Day, so something to defiantly consider ("Tangrowth's mixed set in the analysis is something that is hard to handle under Sunny Day conditions, so it is something to consider when using it.").

Exeggutor - Of all the Chlorophyll Pokémon, Exeggutor has the highest Special Attack, making it a pretty effective sweeper under Sunny Day. With the use of Chlorophyll, Exeggutor has the capability to reach a monster 418 Speed stat, which outspeeds Choice Scarf Heatran and others (With a neutral nature or positive nature? Please explain). Furthermore, Exeggutor has access to moves like SolarBeam and Stun Powder (Stun Powder? Do you mean Stun Spore and Sleep Powder?), making it a pretty effective Pokemon, and also has access to Explosion, so once Exeggutor can't go at it anymore, it can explode and possibly take down one Pokemon (Seperate "Pokemon" and "and". Then: "It also has access to Explosion, so once Exeggutor can't go at it anymore, it can explode and possibly take down another Pokemon.").

Infernape - Infernape makes a hard ("hard" makes me think that it is a difficult sweeper. Perhaps "an excellent sweeper" could do better, but optional.) sweeper all around, being able to hit hard from both sides of the spectrum makes this Pokemon a great option, even for a Sunny Day team (Seperate "around" with "being". Then: "Being able to hit hard from both sides of the spectrum makes this Pokemon a great option, even for a Sunny Day team."). Infernape's STAB Fire Blast can become even ("even" is unneccesary) more deadly under Sunny Day, as it gets a 50% boost from Sunny Day, making it Infernape's secret weapon. Infernape has the option of running Choice Band, Choice Specs, or Mixed, (Simply put a period after the first "Mixed") Mixed would be the most recommended as it has access to Grass Knot (Infernape also learns SolarBeam, which will hit as hard as Grass Knot does (Not all the time. Grass Knot is hitting less against Pokemon such as Vaporeon, Blissey, etc. Perhaps "heavier opponents" would best describe the equality of power.)), and hits hard with Hidden Power Ice, giving you a check against Dragon-types, while Grass Knot prevents it from being walled by bulky waters, and Close Combat hits things like Blissey hard (After the parenthesis statement, I'd put a period there and then write the following: "Hidden Power Ice hits Dragon-types while Grass Knot prevents it from being walled by bulky waters. As for Blissey, Close Combat will eliminate her as a threat."). You can also run Choice Scarf, which can pack Sunny Day and U-turn, Close Combat, and Fire Blast, making it a amazing sweeper, while being fast enough to set-up a Sunny Day or U-turn. (I'm a little confused. I mean, I understand the gist of it, but the problem comes down to it's locked onto one attack after use. But maybe it's just me.)

Entei - Entei is one of the few Fire-type Pokemon that has access to SolarBeam and Calm Mind, which makes Entei one of those Pokemon that you really want on a Sunny Day team. Entei can also hit from both sides of the spectrum, but not as hard as Infernape, (remove the comma) due to its low base Attack (this isn't true. Entei has a 120 base Attack compared to Infernape's 104.) and limited physical movepool, so Entei is better off being a Choice Specs Entei or Calm Mind Entei ("Choice Specs or Calm Mind-user"), it has SolarBeam, which benefits a lot in Sunny Day ("it has SolarBeam..." is already mentioned. I'd say ommit it.).

Heatran - Heatran is that Pokemon with that awesome typing, Steel-type and Fire-type, making it be able to handle Dragon-types to some extent, and gives it the ability to handle many Special Attacks that are thrown at it ("Heatran is a Pokemon with the awesome Steel and Fire-typing, making it able to handle Dragon-types to some extent and many Special Attacks that are thrown at it."). Heatran makes a good use of both Choice Specs and Choice Scarf, and also has access to SolarBeam, (ommit the comma) like all other Fire-type Pokemon (Flareon would like to have a word with you.), making Heatran another Pokemon that will enjoy Sunny Day for the 50% boost of its Fire-type attacks.

Houndoom - Base 110 Special Attack is not bad at all. Houndoom becomes a beast when given Choice Specs, with access to SolarBeam, and the boost of its Fire Blast (place "and" here) thanks to Sunny Day (Flash Fire makes this even greater. Something you missed on Heatran too), it can be pretty dangreous. Though its Speed can be a let down for some, its ability to counter Psychic-types such as Azelf, thanks to its part Dark-type (add a comma here) shouldn't be overlooked!

Magmortar - Magmortar is is (remove one of the "is") another great Fire-type Pokemon that should be an option for a Sunny Day, mostly because of its possible sweep with a Mixed Attacker set, something that is often overlooked (and is something that is often overlooked could help remove the comma). Magmortar, like Infernape, can hit hard from both sides of the spectrum, so its ("it is" or "it's") capable of running both a Choice Band and a Choice Specs set, but with its access to SolarBeam, and its 125 Special Attack, plus the boost from Sunny Day, Fire Blast means danger (Try: "but with its access to SolarBeam, a 125 Special Attack stat, and the boost from Sunny Day, Fire Blast means danger."). Magmortar does not really care of ("of" should be "about") Flash Fire like other Fire-types though, (remove the comma) due to its access to Focus Blast and Cross Chop, though both ("of the" should be placed here) attack's accuracy is shaky.

Typhlosion - Typhlosion is great in Sunny Day with Choice Scarf, (here the comma is unnecessary) or Specs. In fact, Modest Typhlosion manages a to 2HKO (50.23% - 59.14%) with a Choice Specs Eruption under the sun, to a 651 HP / 385 SpD Blissey. Unfortunately, Stealth Rock somewhat ruins this, but still, it is great option to consider.

UU:

*Note: Although most of the useful Sunny Day sweepers are listen for UU, the following Pokemon are fully capable of performing with excellence in OU as well, with the support of Sunny Day of course.

Bellossom - Not the best sweeper under Sunny Day, but still have some effectiveness.

Shiftry - Shiftry is one of those Pokemon that can play both the role of a physical or special sweeper, though it really wants more Special Attack and Speed. Shiftry's part Dark-type means it has the ability to learn Dark Pulse, giving you a chance to eliminate things like Grumpig and Hypno without having to pack something specifically for both these Pokemon.​


Tropius - Pretty much on the same page as Bellosom, not really the best sweeper under Sunny Day, but things like Sword Dance make it differ from the others, as Tropius is really one of the Pokemon that can actually work (with) a physical set under Sunny Day. Tropius holds the ability Solar Power, which makes its Special Attack increase well, incredibely, (remove well and just put "incredibly". Also remove the commas) packed with a Choice Specs, very little will be resisting this powerhouse ("Packed with..." on should be a new sentence).

Victreebel - Victreebel is probably one of the Pokemon that most shines in a Sunny Day team ("that shines the most in a Sunny Day team".). Victreebel is a (remove "a") much better (place "than" here) Shiftry in terms of being able to attack from both sides of the spectrum, (place "thanks to") base 105 Attack and base 100 Special Attack is something that shouldn't be overlooked ("...Special Attack, which is something that shouldn't be overlooked."). It has access to Swords Dance, which makes it a pretty effective physical sweeper considering it has the ability Chlorophyll, packed with Swords Dance can mean it can destroy a lot if used correctly ("...Chlorophyll. Packed with Swords Dance, it can destroy a lot if used correctly.").

Vileplume - Vileplume can be (place "a" here) pretty annoying Pokemon under (technically, "behind" would describe it better) a Substitute, (Break the next section as a different sentence) thanks to its part Poison-type, it handles Fighting-type Pokemon much better than the others. In offensive terms, this Pokemon does the same thing as the other Sunny Day Sweepers do, though it won't make much use of Chlorophyll thanks to its slow base Speed ("low" should replace "slow" or ditch "base" altogether).

Sunflora - Its probably (Probably?) one of the Sunny Day sweepers with a high base Special Attack. It might not look like much, but Sunflora has access to Solar Power, which packed with a Choice Specs reaches an insane Special Attack stat, (Break this sentence here) with SolarBeam and Sunny Day at hand, not much will be stopping the massive destruction this can cause. (Another thing to note is Trick Room support. With Expert Belt + Sunny Day + Trick Room support, Sunflora is a deadly sweeper in UU from the experience I've had with it. This obviously assumes you're using Solar Power by the way.)

Rapidash - Rapidash is a great Sunny Day sweeper in UU, regardless about what they say ("others" over "they" IMO). Rapidash is the only Fire-type Pokemon that gets access to Megahorn (though its accuracy isn't the best), making it the only Fire-type Pokemon in UU who won't get walled by Hypno and Grumpig, and Claydol as well ("...who isn't walled by Hypno, Grumpig, and Claydol." Also, this is only partially true because Ninetales with Dark Pulse beats Grumpig while Sun-boosted Fire Blast is handling Hypno and Claydol decently.). Rapidash also has Hypnosis in its support movepool, (Seperate these clauses. Also, start with "It may" over "But".) but not have the best accuracy, but its ("it is" or "it's") still something to look in Rapidash.

Ninetails - Ninetails, the terrorific Fire-type Pokemon of UU. Ninetails absolutely loves Sunny Day, with it knowing Nasty Plot, access to SolarBeam, Ninetails can leave opposing teams in fear (Perhaps "Ninetales absolutely loves Sunny Day. With it knowing Nasty Plot as well as access to SolarBeam, it can leave opposing teams in fear."). Ninetails also gets Hypnosis, again not the best acuracy, but should be considered.

Flareon - DPP blessed Flareon with SuperPower, giving it ("an" should go here) edge against Clefable now. Flareon is able to cause a lot of havoc with its Mixed Sweeper set, and is even more deadly in Sunny Day. Flareon might not have access to SolarBeam like the other Fire-types, but (place "it" here) can still make use of Hidden Power Grass, so Flareon won't be fearing Water-types either.

Castform - This is probably the weakest option if you consider judging Pokemon by their stats, but under Sunny Day its attack "Weather Ball" can become somewhat lethal, (Break here IMO. Remove "but" and start with "Otherwise,") but otherwise, this little guy can be used for setting up Sunny Day as well.

Wormadam - Woemadam (Lol Woemadam. I think you mean "Wormadam") does ("may" might be a little better in here, though you're absolutely right about that it does not have a good movepool period) not have the best movepool, but its ("it is" or "it's") able to cause damage in UU with the use of Sunny Day, (remove the comma) due to it being able to use SolarBeam, packed with a Choice Specs can cause quite some damage (I think the second part: "packed with..." should 1) be a seperate sentence and 2) rephrased a little bit. Try: "Packed with Choice Specs, Wormadam can cause a lot of damage.").

Support

OU:

Celebi - An extremely useful Pokemon for a Sunny Day team in the OU (if you use "the", place "environment" here. Otherwise ditch it.). Celebi will be the Pokemon that will be stopping things like Swampert from stopping your Sunny Day in its tracks, and furthermore, it will also be stopping Pokemon like Vaporeon and Suicune as well, go can be come very annoying for Sunny Day teams (a little confusing of a sentence. First off, how is Swampert stopping Sunny Day? I'd say Tyranitar or Hippowdon stop it sooner than Swampert. Now as far as "sweeps", that is a different story. So try this: "Celebi will be the main Pokemon to stop things such as Swampert, Vaporeon, and Suicune from ruining your team's sweep."). Celebi has access to Thunder Wave and Recover, (here a semicolon would work better. Or break the second part into a new sentence.) Thunder Wave will provide some paralysis support, mostly used so you feel safer using your set-up Pokemon, such as Victreebel.

Dugtrio - One of the best revenge killers out there, and it has a reason for that. You will sometimes find Pokemon like Tyranitar ruining Sunny Day teams, but Dugtrio is here for that. Dugtrio has STAB Earthquake, which will ensure an OHKO on Tyranitar, eliminating and becoming ("eliminating" is a lot better alone. Remove "and becoming") one less thing (IMO "threat" over "thing". Up to you) to worry about.

Cresselia - Sunny Day teams tend to have problems (here a period would be needed after "problems" and re-phrase the next part. OR simply place "with" in here.) Dragon-type Pokemon in OU, mostly Salamence. Cresselia can be called the "#1 counter" to Dragon-types, as it can handle Dragon-type Pokemon with great effectiveness, and having Cresselia in your team will make you feel more confident when facing Pokemon such as Salamence and Dragonite (Why? Basically you've stated that it's great, but no reasons to back it up. Now if you say this: "Cresselia can be called the "#1 counter" to Dragon-types. With access to Reflect, Light Screen, Thunder Wave, and Ice Beam, there is little to worry about when Dragonite and Salamence are of concern." Something similair to this.). Moonlight benefits from Sunny Day, which will heal 2/3 of Cresselia's HP.

Moltres - Moltres is once again mentioned here, as its ("it is" or "it's") a support Pokemon as well. Despite its horrific weakeness to Stealth Rocks ("Stealth Rock"), Moltres makes a great counter to Fighting-types and others, and is able to set up Sunny Day as well.

Rhyperior - Rhyperior is the OU version of Camerupt, which is a pretty good option as well. Thanks to Rhyperior's awesome ability, Solid Rock, Rhyperior takes much less from Water-type moves, ("thus" might work here before "giving", and also Sunny Day halves Water-type attacks, which isn't really mentioned in here.) giving some more bulk to this Pokemon. Rhyperior is also able to learn Sunny Day, (remove comma and place "and" here) Stealth Rocks ("Stealth Rock"), which also makes it a good support Pokemon.

UU:

*Note: Although most of the useful Sunny Day sweepers are listen for UU, the following Pokemon are fully capable of performing with excellence in OU as well.

Leafeon - Possibly the best bulky water eliminator for a Sunny Day team. Having the ability "Leaf Guard", it makes Leafeon heal much faster from status moves such as paralysis, making (place "it" here) a pretty effective bulky Grass-type Pokemon. Leafeon also has access to Swords Dance, and with its amazing bulk, its ("it is" or "it's") capable of causing havoc after a few Sword Dances.

Altaria - Altaria is here for opposing Fire-types that trouble Sunny Day teams, (here a semicolon would work better than a comma. Even a colon would work as well) not just any regular Fire-types, but Fire-types such as Flareon, who have Flash Fire, making Grass-type moves and Fire-type moves have no effect whatsoever on Flareon, ("these specific Fire-types" since you're outlining more than one Fire-type altogether (you're using Flareon as an example). Also, Grass-types have "little" effect on Flareon, so saying that it has "no" effect is saying that it is immune to the impact, which isn't true. It could be worded different like so: "...not just any regular Fire-type, but Flareon. Flareon has Flash Fire which gives Flareon a boost if it switches into a Fire-type attack. Grass moves are not very effective on it either, so it causes trouble for Sunny Day teams to bypass." Something similair to this) and (remove "and", then start a new sentence with "Altaria") Altaria is one of the best counters to Flareon, so Altaria is one of those Pokemon one ("that" > the second "one") should ("be" goes here) really consider ("considered") when making a Sunny Day team.

Camerupt - Having such a great typing, decent stats, and a good support movepool make this Pokemon what it is in a Sunny Day team, (colon works better than a comma) fantastic. Camerupts ("Camerupt's") typing allows it to have immunity to both Thunder Wave and Will-O-Wisp, and also have immunity to Electric, this combined works amazingly in UU, and furthermore, it is totally a Pokemon that works in OU Sunny Day teams, to keep things like Heatran and Zapdos on check (Long-winded. Try: "Camerupt's typing allows it to have an immunity to both Thunder Wave and Will-O-Wisp, which otherwise cripples your team's sweepers. Furthermore, its immunity to Electric-type attacks as well as its abundant resistances make Camerupt a Pokemon that not only can be utilitzed in UU, but also in OU to keep threats such as Heatran and Zapdos in check.") Camerupt also has access to moves to ("such as" over "to) Stealth Rocks ("Stealth Rock") and Yawn, (Period after Yawn.) Stealth Rocks ("Stealth Rock is") for team support and Yawn (place "is" here) for some possible scouting. (Roar is also useful for scouting since it works outside of Sleep Clause. Yawn, on the other hand, becomes ineffective after the Pokemon falls asleep (assuming a SleepTalker) Might be worth mentioning.)

Magcargo - Though its typing isn't the best, but (remove one of the following: "Though" or "but") it has a good handful of support moves (place "that" here) Sunny Day teams can use. Magcargo has access to Stealth Rocks (Stealth Rock) and Yawn, making it a pretty much inferior Camerupt. (Well, there are a few more uses for Magcargo so I'll outline them. First off: Recover. Second, Screens. Third, it's ability, Flame Body. So really it's a little different from Camerupt and hard to compare the two of them.)

Shuckle - Shuckle is one almighty (IMO "almighty" is a little redundant with "bulky", but is optional I guess) bulky Pokemon. Shuckle is a support Pokemon mostly (A comma is needed after "Pokemon". "not only" works better than "mostly") because of its ability to learn Sunny Day (like every other Pokemon lol) and having access to Stealth Rock, but ("but also" fits here) being able to bring down things with Toxic. Shuckle also has Encore, which can be extremely annoying for the opponent (Emphasize why perhaps? Optional.).

Venusaur - Venusaur is a ("an") extraordinarily ("extraordinary") Grass-type Pokemon, (Break these into two sentences.) with some ("its" over "some") amazing defenses, this Pokemon is capable of handling things (I'd say "threats" over "things" personally but again, preference) such as Hitmonlee, while it has the ability to learn Swords Dance, making it a pokemon that can be both defensive and offensive and be good at either one (Alright, break this into two sentences after "Hitmonlee". Then rephrase the sentence like so: "Venusaur is a Pokemon that can utilize both sides of the offensive spectrum effectively. Physically, it is able to learn Swords Dance with moves such as Seed Bomb, Return, and Earthquake to back it up. Specially, Venusaur has an excellenet Special Attack stat as well as attacks such as SolarBeam, Hidden Power, and Sludge Bomb to utilize." I've also noticed that you haven't mentioned it being able to learn Sleep Powder: something that is very important here IMO.).

Hitmontop - "What the hell is it doing here?" Hitmontop will be helping out here with Pokemon such as Lapras, as it has access to Stone Edge, and Mantine as well, while being a pretty nifty Rapid Spinner as well (Okay I get it. But Close Combat is doing more damage to Lapras than Stone Edge. Now for Mantine that's what it's for. So re-arrange it like this: "Hitmontop will be helping out with Pokemon such as Lapras with Close Combat. As for Mantine, Stone Edge will shut it down. Hitmontop is also a nifty Rapid Spin user as well."). Hitmontop also makes a check for Clefable, who can pretty much dominate a Sunny Day team if not prepared for.

Threats

Tyranitar - Weather teams' biggest enemy, (two options: use a colon instead of the comma OR ditch the comma and put in "is") Tyranitar. Its ("It is" or "it's") not much the Pokemon itself, its its ability ("it is Tyranitar's ability" works much better here), Sandstream, which automatically brings Sandstorm into play when this Pokemon is summoned. With its high Special Defense ("thanks to sandstorm giving it a boost" should be placed here), Fire-types won't be doing much to it, mostly because of its part Rock-type (Also mention that users of SolarBeam are required to have a turn to charge. And I'm not 100% on this, but I think SolarBeam recieves an attack cut).

Tyranitar can be brought down by Dugtrio though, and with much ease (I wouldn't say "with much ease". The trouble is getting Dugtrio in, which it can't switch into any attack except maybe a lucky Thunderbolt. Now saying that Dugtrio can trap and revenge kill Tyranitar is a different story), so its ("it is" or "it's) not really something you should worry about if you have a Dugtrio in your team (missing a period here)

Hippowdon - This is (remove "is) too (place "is" here) a threat, (remove the comma) thanks to Sandstream again, but to a lesser extent. Its ("It is" or "It's) a Ground-type, meaning it won't be able to handle Grass-type Pokemon at all, so something like Vileplume or Celebi should be able to handle it (place "to" here) much affluence.

Abomasnow - Abomasnow is a threat as well, due to its ability of changing the weather, but Sunny Day teams can handle Abomasnow well, as Sunny Day mostly packs Fire-type Pokemon ("Abomasnow is a threat as well due to its ability changing the weather. Most Sunny Day teams pack a Fire-type; however, Grass-types should be aware of the 100% accurate Blizzards when facing Abomasnow.").
Blissey - (Remove this "Blissey")

Vaporeon - Bulky Waters like Vaporeon will always be a threat to Sunny Day teams that don't carry a Grass-type Pokemon, but not many teams are seen without a Grass-type, so its probably not something to worry about much. (Okay...?)

Suicune - Suicune goes on the same page as Vaporeon, which Calm Mind variants are probably more threatening, as after a few Calm Minds it will be causing havoc with Ice Beam and Surf, but Yawn can handle it, as well as Roar ("Suicune follows the same page as Vaporeon. Calm Mind, on the other hand, makes Suicune very different from Vaporeon. After a few Calm Minds, it can cause havoc with Ice Beam and Surf. Yawn can handle most Suicune as well as Roar.").

Swampert - Swampert is a real pain in the ass, but Celebi handles Swampert like there is no tomorrow, andso does (remove the comma and "and" and place "as well as" in place of the phrase between "tommorrow" and "any") any other Grass-type, (Remove the comma and seperate these two sentences. Remove the "and" and place "Once again" in place of it) and again, Sunny Day teams rarely go without a Grass-type Pokemon.

Heatran - Heatran's Flash Fire is something that can trouble a lot ("...that can be troublesome" works better than "that can trouble a lot" IMO. The next phrase should be a seperate sentence.), as it makes Fire-type moves useless ("Heatran makes Fire-type moves useless thanks to Flash Fire" works well here), and ("while" can work over "and") Grass-type moves won't even scratch Heatran. Camerupt can handle Heatran, not the best answer, but is pretty reliable (Okay. Now tell me how many times Camerupt is going to want to switch into an Earth Power again? Now try: "Camerupt can switch into Heatran that aren't locked into Earth Power. It isn't the best answer to Heatran, but is reliable in doing so thanks to STAB Earthquake."). Cresselia can also get some action going on, but might require to pack Calm Mind and Hidden Power Ground, which isn't really recommend to do.

Salamence - Dragon-types are also problems, as Salamence resists both Fire-moves and Grass-type moves. Dragon-type Pokemon problems can easily be eliminated by Cresselia though.

Blissey - With a monster base 255 HP and base 135 Special Defense, it can be an unpleasant Pokemon to fight with a Sunny Day team, (comma isn't necessary. Remove) due to the fact that most of Sunny Day Teams (decapitalize "teams" are composed of the special side of the spectrum. Dugtrio can revenge kill it, though it can be a possible 2HKO, and Infernape has Close Combat, so its not really something to break a sweat about with the proper Pokemon ("Dugtrio can possibly 2HKO Blissey while Infernape can handle Blissey with Close Combat. With the proper Pokemon, this shouldn't be an issue.").

UU:

Quagsire - This also goes under the bulky water type category, (Break these into two different sentences) Grass-type Sunny Day Pokemon will handle it.

Gatrodon - See above.

Lanturn - Lanturn resists Fire-type moves, and Grass-type moves to some extent, though Lanturn won't be taking Choice Specs SolarBeams well.

Lapras - Lapras isn't much of a threat, mostly because of its weakness to Stealth Rocks (Stealth Rock), but still something to look out for (STAB Ice Beam and STAB Surf sure hurts Grass and Fire-types respectively though...).

Golduck - Golduck is probably the Water-type you should look out for the most, as its Cloud Nine ability will (remove "will") nullifies Sunny Day, but Golduck is be (remove "be") dominated by Grass-types. (If you're reliant on SolarBeam, Golduck isn't caring because it requires you to charge for two turns. Worth a mention.)

Mantine - Mantine is probably a problem that's hard to counter. Mantine also has a horrible weakness to Stealth Rocks ("Stealth Rock"), so your best bet is to have Stealth Rocks ("Stealth Rock") in play and either Yawn or Roar.

Clefable - With its base 90 Special Defense and base 95 HP, it can be a potent thread that can shrugg ("shrug") off Special Attacks with ease, but can be defeated by Sunny Day Sword ("Swords") Dance sweepers, (remove the comma) such as Leafeon and Tropius, (seperate these two clauses into two different sentences. Remove "and" and use "The" to begin the sentence.) and the easy way out would be using Hitmontop.

Conclusion

I hope you atleast got an understanding about how Sunny Day works, and what its supposed to be composed of, now its time for you to put yourself to the test, and make your own Sunny Day team, let it be for OU or UU, you can hopefully now make a good Sunny Day team, just don't forget there is no such thing as "too much Sunny Day"! (See the first person reference. Also seems long-winded. Try: "Hopefully, you at least got an understanding about how Sunny Day teams work. Since you know what it's supposed to be composed of, now it's time for you to put yourself to the test and make your own Sunny Day team. Whether it is OU or UU, you can hopefully make a good Sunny Day team: just don't forget there is no such thing as "too much Sunny Day"!")
I've bolded my suggestions and such, so please look over it. I've probably missed some parts, but hopefully someone else can go through and scan this. Just post here or in PM if you have a quesiton, I'm here to help!

I've finished with what I could find. So here I'm going to ask a few things:

- You haven't mentioned Ubers much. Is there a reason why? Just wondered.
- An example team for both OU and UU environment would be nice to put in here. I'm guessing you're working on it, but it is nice to have an example to look at for new and inexperienced users that are trying to build such a team.

thanks a lot for that grammar check!

well to be honest, I don't really see much action of this Ubers, and its meant for UU / OU, but I can see where you're coming from, thing is I don't have any experience with Sunny Day in Ubers, but I will be writing a paragraph or 2 about Ubers.

Jumpluff - One of the fastest Pokemon of the UU, which it's able to learn Sunny Day as well. Jumpluff makes a great option as a lead; not only because of its stellar Speed, but its other moves, such as Sleep Powder and Stun Powder make it a great option. It has access to U-turn, which allows Jumpluff to switch safely from harm right after setting up the sun. In short, this gives Jumpluff the ability to set-up Sunny Day again if needed. Encore is another surprise move on Jumpluff, being able to get the opponent stuck in one move can allow Jumpluff to proceed and set-up Sunny Day.
I read through this and one thing jumped out at me. Shouldn't Stun Powder actually be Stun Spore?

There are a still things that I would like to see fixed here, before this gets converted to HTML. There were a few obvious things like "Sword Dance," and also a few misspellings (Bellosom). Also there are a few bits that I feel could be explained a bit better. For Example, "Why is Bellossom bad in the Sun?" I feel more explaination is neede in some areas, I don't have the time today, so I will go over the whole thing tomorrow and see what I can find.

Off the top of my head, I'd say expand the Bellossom bit, and anything that doesn;t seem to have reasoning. For example "This is bad" should be "this is bad for reasons XYZ..." etc... I'd also ensure you add the sprites (from the smogon sprites), so that it looks similar to the Rain and Hail guides. I trust your grammar Twash ;) I'll take a look over the HTML when it's done I guess!

I can change spellings and grammar when I HTMLize, I can proofread before doing so. I mean is there any more additional Pokemon, strategies and so on that need to be added.
