My Second Successful OU Team

[Skarm™]

Hey there. This is a team I made while I was bored, but when I tested it out it actually worked great, so I wanted to see if you guys share my opinion on that. Here it is!

Oh yeah, one more thing. This isn't the actual order of my team, it's the order of the Pokemon I chose to be in it.

Teambuilding Process

I wanted to start with a stall Hippowdon. So I actually made a home-made set which you'll find later, that turned out well until I battled this monomove(ikr, it sounds weird), and the one move all of them used was Taunt, so yeah...

Next I wanted something that couldn't get toxic'd and that could tear a team to shreds, a deadly immune sweeper. And that would be my amazing friend, Genesect the boss.

Next I wanted another deadly sweeper that can abuse the power of a Choice Band. And because Terrakion was voted the hardest Pokemon to switch into, I used it. It OHKO's things with Close Combat that you never would've imagined, like Kingdra, lol.

Next I wanted a spinner, as I really might need in some cases, and something that could set up Toxic Spikes like this (*snaps*), and that would. undoubtedly be, Tentacruel.

Next, I needed a priority move, and a Pokemon that most people wouldn't see coming regularly, but still deadly. With access to a STAB Pursuit, Ice Shard, and Low Kick, this one knows it's place, and it has perfect typing for those offensive things. As for defenses, look out Weavile, you're in for it rough.

Everybody knows Rotom-W, I mean who wouldn't. Everybody knows what it can do with a Choice Item, so I decided it would be my water and electric sweeper, and then maybe use Trick if it needs too. This thing has ripped apart teams, so say hello, and prepare to say goodbye as it beats you.

Hippowdon wasn't doing so good, so I replaced it with the famous Dnite. With Multiscale, it can get a Dance in easily, even on an Ice Beam, and then sweep.

I switched Weavile for Mamoswine because Mamoswine has EQ, also has Ice Shard, Superpower, and Stone Edge. Plus it can hit hard.

A Detailed Look

Dragonite @ Leftovers
Multiscale
Adamant
72 HP, 252 Atk, 184 Spe
Dragon Dance, Outrage, Fire Punch, Extremespeed

This thing really hurts. The already bulky behemoth enters with newfound armor, found in Multiscale and HP EVs. It just easily grabs a Dance, then sweeps. This monster is underestimated, but it's your team that's gonna be gone, not mine...

Genesect @ Expert Belt
Download
Timid
4 HP, 252 SpA, 252 Spe
Thunderbolt, Ice Beam, Bug Buzz, Flamethrower

The first thing you might notice off the bat is that I have Bug Buzz instead of Flamethrower, and i would've used Flamethrower, but I actually replaced it with Rock Polish. It's a free speed boost on stall Pokemon, but if you think I should have Flamethrower instead, please say so, because I'm perfectly happy with both. This thing really either KOs or severely dents, so be careful around it.

Terrakion @ Life Orb
Jutsified
Jolly
4 HP, 252 Atk, 252 Spe
Earthquake, Stone Edge, X-Scissor, Close Combat

Remember how I said Terrakion was voted hardest Pokemon to switch into? Yeah, it's true. It has amazing offensive typing, as well as good defensively(sometimes), and can also rip the other team apart. With max Attack, and a Choice Band, man will you be scared of this!

Tentacruel @ Black Sludge
Rain Dish
Bold
252 HP, 240 Def, 16 Spe
Toxic Spikes, Rapid Spin, Scald, Protect

This set works pretty good. I'm usually the more offensive trainer, and I've only mastered one stall Pokemon, Vaporeon (<3), but I'll try Tentacruel too. Black Sludge for the poison leftovers and it tricks Trick Rotom(lol that sounded weird). Protect really isn't working that great, and I already have like 3 Ice moves, so no Ice Beam, so I don't know what to do there. Spinners FTW, and please tell me anything I can do to make Tentacruel better.

Mamoswine @ Choice Band
Thick Fat
Jolly
4 HP, 252 Atk, 252 Spe
Ice Shard, Superpower, Earthquake, Stone Edge

Mamoswine can certainly do some damage. With priority Ice Shard and EQ STAB(and a prioriry too), it can take it's job seriously, and take it seriously on the opponent. XP

Rotom-W @ Choice Specs
Levitate
Modest
4 HP, 252 SpA, 252 Spe
Volt Switch, Thunderbolt, Hydro Pump, Trick

Unlike most people, I use both Volt Switch and Thunderbolt, because I know there's gonna be that one Pokemon that has just enough HP to survive a Volt Switch, but Tbolt kills it. It's infamous Trick tricks stallers, forcing them to use Choice Items to their peril.

Anyways, that's my team. I've used it like 100 times, becuase I love it, and I've probably won 80% of the time, and 10% was from opponent's rage-quitting because of Genesect. Please rate from 1/10 and suggest things! Thanks!​

Nice team.

Substitute + Calm Mind Jirachi looks like the most problematic threat. It gets the chance to set-up on Terrakion or Weavile locked into an ineffective attack, set-up, and threaten a sweep. Jirachi can put up a substitute, get in a Calm Mind, and can do major damage with Thunder and Water Pulse, requiring you to sacrifice something to break its substitute and try to KO it with Terrakion's attacks. The lack of Stealth Rock also hurts this team's effectiveness, as without it, you're giving threats like Shell Smash Cloyster, Dragon Dance Dragonite, and Volcarona an advantage over your team, and making them that much tougher to deal with. For example, without Stealth Rock down, you're going to have a harder time taking Volcarona out with Dragonite's Extremespeed while it can launch away with boosted Fire Blast / Fiery Dance.

Firstly, I'd suggest a Weather Trapper Heatran over Genesect. Jirachi's main draw is its ability to function in the rain, remove its desired weather, and you have effectively neutered it. Thunder loses power and accuracy, while Water Pulse becomes 50% weaker. Once Heatran has removed Politoed with a combination of Magma Storm + Sunny Day + Solar Beam, it will remove any of Rain's weather effects and neuter other weather dependent threats to, like Swords Dance Toxicroak. However, if you face Choice Scarf or Choice Specs Politoed, it would be best to take it out with Rotom-W and / or when Jirachi attempts to set-up, remove the rain with Sunny Day from Heatran, and hinder its sweeping potential. Genesect looked liked the weakest link of the team, as removing anything else would make you weaker to more threats, as everyone else checks an important threat. IMO, it is worth trying out Heatran over Genesect, as you still have plenty of offensive power, but you also threaten weather reliant teams even more, removing their precious weather starters and their effects.

Lastly, try a Life Orb +3 Attacks Terrakion with Stealth Rock as the last move. With this set Terrakion can still threaten the opponent with its moves, and the ability to switch moves gives less threats the chance to set-up. In addition to this, Stealth Rock limits the effectiveness of several threats like Thundurus, Tornadus, Dragonite, and Volcarona. Since Terrakion tends to cause a lot of switches, it gives you the opportunity to set-up Stealth Rock. The lack of X-Scissor might seem bad to you, but Weavile is there to trap and kill Starmie and Celebi, the prime targets. The loss of power is worth the change from CB to Life Orb, because Stealth Rock really is that important (and as a bonus, the ability to switch moves!). Just replace Choice Band with a Life Orb, and Stealth Rock over X-Scissor (or even Earthquake).

thanks for all the info, really. there's just one problem. genesect is actually my most versatile pokemon, able to switch moves and beat common types like water and dragon, dark, psychic, etc. don't you think it'd be better to take out weavile instead of genesect, because genesect gets starmie with bug buzz and does 4x to celebi, taking it easily. so do you think it'd be better to replace weavile?

 

[afterburn]

Nah, Weavile is your main weapon to take out Tornadus, Thundurus, Outraging Dragons (Moxie Salamence, e.g.), and Calm Mind Reuniclus, taking it out would leave you a little open to those threats. Weavile can still beat celebi and starmie, the former you can lure out with Rotom's Volt Switch, and then it becomes a matter of "do i pursuit? or do i night slash?" all those things you mentioned, Weavile takes out the same stuff for the most part. Starmie especially becomes more troublesome, as does Life Orb Latios (with Psyshock), the former in rain (if Heatran hasn't taken out Politoed yet) can take out Rotom-W with hydro pump for a 2HKO, and Weavile is the one 'mon who can take it out.

Also, if you want you can keep Choice Band and try Stealth Rock over X-Scissor or Earthquake if you don't like the loss in power. Just know that it makes you more prone to set-up, and gives things like Sub DD Gyarados and Trickroom Reuniclus more opportunities of set-up (and both can leave a dent).

okay, ill try it out and let you know how it goes.

EDIT: i tried heatran, and im sorry to say it was HORRIBLE

 

[Shining_Latios]

Hey, cool team man. First off, I suggest is using Sacred Sword / Quick Attack over Earthquake on Terrakion. Earthquake provides redundant coverage, Close Combat basically hits the same stuff. A Jolly Nature should also be used instead. Terrakion is already hitting massively hard with a Choice Band and a Jolly Nature allows it to outspeed as many Pokemon as possible which is important. A pretty big threat I see to your team is Specs Latios. You have nothing to take a Draco Meteor, bar Genesect which even takes 62.89 - 74.2%. Another thing I noticed is you lack Stealth Rock, which is great for an offensive team like this. I highly recommend you use a Specially Defensive Jirachi in place of Weavile, as it is capable of taking Draco Meteors and putting Rocks up. The moveset of Stealth Rock / Wish / Body Slam / Iron Head should work wonders, with an EV Spread of 252 HP / 224 Special Defense / 36 Speed, a Careful Nature, and Leftovers. Specially Defensive Jirachi provides you with a nice counter to both Specs Latios and Tornadus-T, who otherwise would give your team nightmares. Jirachi also gives your team Wish Support, which can be extremely useful to keep your Pokemon alive as they all lack recovery moves. Jirachi as well provides you with paralysis support as it has a 60% chance to paralyze something with Body Slam. This combined with Iron Head allows you to put severe pressure on your opponent as you wear them down with the ParaFlinch combination. Trick Room Reuniclus also looked like a hassle to them, so Jirachi is able to take its attacks nicely. My next suggestion would be to Scarf Genesect, replace Bug Buzz with Flamethrower, replace Rock Polish with U-turn, giving it a Naive Nature, and putting the 4 HP EVs into Attack. Scarf Genesect gives your team an effective revenge killer allowing you to take down a good amount of the metagame with it's fantastic movepool and stats. Scarf Genesect will be able to provide your team with momentum throughout games with U-turn which can pester opponents. A Naive Nature is used so your U-turns are stronger since Timid lowers Attacks. Genesect is able to outspeed +1 Dragonite and OHKO it as long as Multiscale is broken. Genesect's ability, Download, will also help it tear through teams with Download boosted U-turns which goes good with Rotom-W for VoltTurning. My final suggestion is possibly trying out Modest over Timid on Rotom-W for maximum power. Hope I helped and good luck.

cool, i'll test it out right now and see how it goes.

EDIT: i have a few things to say. i think this genesect would be better not scarfd, because all the moves it has are for sweeping multiple types, thats its purpose, not to half-sweep with one. also, modest is ok, it works practically the same with rotom w/ timid nature. i think terrakion would be better witha life orb for the set it has, and i'm not gonna use sacred sword unless its not choiced, so either i keep choice and let go of sacred sword or let go of chocie and keep sacred sword(what should i do?). oh yeah, jirachi's ok, its just that some things ruin it. so what now?

 

[bluewooper]

Hey Skamory7. I felt like rating a team so I decided to rate yours, since you had a Weavile on it. Weavile is cool. Anyway, I found a few things that you can change to make your team a bit better. Here goes.

Ok, you are running your Dragonite sret to outspeed as many things as physically possible, by running 252 Speed EVs. I find this to be a little bit excessive, seeing as some of these EVs can be used to make you a little bulkier, while still being able to outspeed key threats after a Dragon Dance. I would like to recommmend to you a new EV spread that can help you retain some bulkiness, while maximizing power and allowing you to outspeed key threats. I recommend that you use 72Hp/252Atk/184Spe: Adamant. This EV spread really helps your team, as it allows you to outspeed Timid Starmie, which is a good speed tier to hit, since you'll only be outsped by Tornadus Therian and random 120s after a Dragon Dance. Also, Jolteon will outspeed you and challenge you with HP Ice. You will lose a bit of bulkiness in this change, but it should be well worth it with your newfound ability to smash threats with a 403 attack.

On your Genesect, you are running maximum speed, which helps helps you tie with other max speed Genesects, which are actually rather rare, since most Naive/Timid Genesect carry a Scarf. I would recommend to you a new EV spread that can help you conserve a bit of your EVs to be used in bulkiness. I would recommend to you a new EV spread of 140Hp/252SpA/116Spe: Modest. This will allow you to outspeed scarved 110s after a Rock Polish (which are the fastest things that you should see in this metagame. lol ScarfJolteon). Now, you ight be concerned that this would effect your ability to attack without a boost. What I would tell you would be that Genesectis great at forcing switches, since he carries supreme type coverage. Also, if you bring him in for the first time after a teammate dies, you will not show your Leftovers (presuming hazards are on the field). The strategy for Genesect would be to come in and Polish on a switch.

Finally, I would like to take a look at your Terrakion's nature. You seem to be running Adamant on Terrakion, which is heavily desirable since it can seriously smash stuff. However, I would recommend that you change your nature from Adamant to Jolly. A Jolly nature allows you to outspeed positive natured 100s, which is such a huge benchmark in the OU metagame. Also, you would have been outsped by pokemon such as Expert Belt Genesect and and Jolly/Naive Landorus, both of which you can now outspeed and smash, instead of getting hit hard by them.

Hey Skarmory7, I hope that I recommended things that you can utilize and have success with with your team. I hope you the best of luck with your team!

 

[LordPenguinFan]

Hey Skarmory 7. My main recommendation is implementing a Mamoswine over Weavile.

Now, while you might miss pursuit and speed a little bit Mamoswine performs the main role that Weavile is filling and has a couple other advantages. As for pursuit, Terrakion is hitting a similar group of pokemon extremely hard with X-Scissor. As for the loss of speed it'll hurt a little bit more, but you won't be missing too much because you already have some pretty fast pokemon: Terrakion, Genesect after a boost, and D-nite after a boost.

Weavile's main purpose is to deal with opposing scarfed dragons. Mamoswine boasts the the same STAB priority but with a higher attack stat to deal with those guys.

Also opposing Hail and Sandstorm teams won't be able to wither Mamoswine down as an added avantage.

Right now a specs Jolteon in the rain can run over your team pretty easily. Providing another immunity for your team would be great. While adding a Mamoswine does leave half of your team weak to grass moves, dragonite and genesect can handle those very well. Also, the most commonly used grass move I see, giga drain, can easily be deterred by putting liquid ooze over rain dish, since you're not running rain it doesn't make too big a difference.

thank you i will try these both out and see how it works out

EDIT: everything works fine except that genesect ev thing. it was better as 252 speed

 

[Jirachee]

Hi

This is a cool team, but you really need Stealth Rock support. That allows you to deal with a lot of threats much easier, such as these incredibly annoying Volturn teams, while also punishing your opponent's switches and denying them from using their Stealth Rock weak Pokemon (such as Volcarona or Dragonite) before they spin them away with their Rapid Spinner, giving them much less option to switch to, making predicition easier etc. It also allows your harder hitters, like Dragonite, to KO their usual checks easier and wears down bulkier Pokemon that have to switch in often if they wall a large part of your team making it much easier to beat them and sweep afterwards. You don't need to change a lot to get that kind of support, just change Terrakion's moveset a bit. Since you are not using a Choiced Terrakion anymore, you can simply use Swords Dance Terrakion with Stealth Rock on the fourth slot. It gets incredible coverage with just its STABs so you will be fine with that, and it causes an incredible amount of switches with its nice offensive presence which will allow you to set up your hazards. It fits an offensive team like yours quite nicely, so you won't have to use something that breaks your momentum a lot.

You will also have an issue with pretty much anything that gets a moderately powerful Electric attack (Rotom-W, Thundurus-T, etc.) since you have no Electric resist. When facing a Rain team, it is very likely that something will try to abuse Thunder on their side which means that every time they click it something on your team loses over half of its health, which is kinda... bad. Volturn teams will have fun against your team as Volt Switch hurts everything on your team a lot, coming from stuff that get STAB on it (not like Volt Switch Mew or Forretress will really hurt you), meaning that your team will lose a lot of health very quickly to the old Scizor+Rotom-W core. To fix this rather quickly you can use your own Thundurus-T over Rotom-W. It gets Volt Absorb, making it immune to Electric attacks and even being able to take advantage of it, which is nice. It will still be able to nuke the opponent with extremely powerful Volt Switches and Thunderbolts, while also being able to nail Ferrothorn with Focus Blast, something Rotom-W can't. It's faster and more powerful, at the cost of a Water resist and a bit of bulk. I think that the Electric immunity is worth the trade off. Its Stealth Rock weakness is rather unfortunate but since you have a Spinner you should be fine.

If you're going to use that Genesect moveset, I'd strongly recommend swapping its held item to an Expert Belt. A lot of people expect Genesect to carry the generic Choice Scarf set, which is extremely deadly but has to lock itself into one move. Using Expert Belt, you can bluff a Choice Scarf set which is amazing, and then surprise your opponent by switching move when they think they will take a resisted hit (such as Ferrothorn coming in after you KO'd something with Thunderbolt.) This will make it much more effective, since it isn't exactly the best user of Leftovers due to its rather pathetic bulk.

Lastly, this is kinda minor but I think that you should go with Leftovers instead of Black Sludge on Tentacruel. If something Tricks your Tentacruel, you don't want them to give Black Sludge to Dragonite as it would be rather unfortunate to see Multiscale scrapped due to its crippling effect. You don't want them to cripple two of your Pokemon, eh?

Anyway that's pretty much it, nice team. Here are the sets you should use:

Terrakion and Thundurus-T

Terrakion @ Life Orb

Jolly
EVs: 4 HP / 252 Atk / 252 Spe

thanks so much for the rate, but i wont be doing thundurus-t. based on somebody else's rates, i switched weavile for mamoswine
