Ok here's the updated list of pokemon that have recieved excellent Abilities from the Dream World. If an ability analysis is one that you created, then do not be annoyed if I change it. I tried to make the analyses as grammatical and informative as possible. If you have something that I didn't include in the analysis that you or someone else created, please speak up and tell me so I can edit it in. A warning before you read: this is a HUGE post.
Blaziken
http://www.smogon.com/dp/pokemon/blaziken
Dream World Ability: Speed Boost
Ability Characteristics:
This Pokémon's Speed is boosted one stage at the end of each turn.
Pros:
Blaziken, while being a powerful sweeper, has been relegated to UU all throughout D/P because of its low speed. However, with Speed Boost, it can utilize its high attacking stats while boosting its speed to become a fearsome sweeper. Coupled with the now boosted Hi Jump Kick, a 135 base power STAB move, Blaziken has the potential to wreck teams all on its own.
Cons:
Blaziken loses Blaze, but that was only useful for Endure+Reversal or pinch berry sets. Speed Boost helps with both of those, allowing it to go faster than enemies trying to revenge kill it while it's at low health.
Staraptor
http://www.smogon.com/dp/pokemon/staraptor
Dream World Ability: Reckless
Ability Characteristics:
Moves with recoil gain a 20% boost.
Pros:
LO Staraptor just got a lot more deadly; Brave Bird and Double-Edge's base power is effectively 216, factoring in STAB. With Close Combat hitting many of the pokemon that resist them SE, Staraptor could also become an excellent Choice Bander. Its good base 100 speed also allows it to sweep against a slower team.
Cons:
Unfortunately, Staraptor loses Intimidate, which helped it to switch in much more easily, but with the huge power of Reckless Brave Bird/Double Edge, once it gets in, the opponent will be hard-pressed to find a good switch-in. However, Reckless recoil and Life Orb will wear down its health very quickly, so it will have problems taking even one hit.
Ninetales
http://www.smogon.com/dp/pokemon/ninetales
Dream World Ability: Drought
Ability Characteristics:
When this Pokémon is brought out, a permanent sun covers the battlefield.
Pros:
A sun team's best friend. With unlimited Sunny Day, sun teams could become a bit more viable. Without a turn needed to setup, a Ninetales lead could use an Escape Button to immediately get in a sweeper scot-free. Things like Jumpluff could finally get some use in OU because of this great ability.
Cons:
Ninetales was never able to abuse Flash Fire well, and Drought allows it to setup a whole team.
Alakazam
http://www.smogon.com/dp/pokemon/alakazam
Dream World Ability: Magic Guard
Ability Characteristics:
This pokemon takes no indirect damage.
Pros:
This is huge for Alakazam; it mostly used a Life Orb or Choice Specs set in UU to wreck stuff with its great special attack. Magic Guard negates Life Orb recoil, allowing Alakazam to attack without fear of KOing itself. But Magic Guard also removes entry hazard damage, allowing the Choice Specs set to switch in and out much more easily after hitting hard with its boosted attacks.
Cons:
Alakazam loses Synchronize, which could be useful to paralyze the pokemon paralyzing it, but Substitute mostly mitigated that threat.
Hitmonlee
http://smogon.com/dp/pokemon/hitmonlee
Dream World Ability: Unburden
Ability Characteristics:
The user's speed doubles after losing its item.
Pros:
Hitmonlee could utilize this along with a pinch berry to boost its attack and double its speed in a single turn by using Substitute or Endure. With access to the now 135 BP Hi Jump Kick, Hitmonlee could become an insanely fast and strong sweeper, only susceptible to priority moves and Hail/Sandstorm.
Cons:
It loses Limber, but the offensive utility of Unburden far outclasses the ability to switch in on Thunder Wave.
Ampharos and Manectric
http://smogon.com/dp/pokemon/ampharos
http://smogon.com/dp/pokemon/manectric
Dream World Ability: Plus and Minus
Ability Characteristics:
The pokemon's special attack increases 50% when on the field with a pokemon with the opposite sign ability.
Pros:
Manectric and Ampharos, while not extremely useful on their own, can become a potent duo when paired with Plus and Minus. Manectric's great speed and special attacking movepool, along with the Minus boost, allow it to bring on the hurt in doubles, while Ampharos' good bulk and great supporting movepool let it help Manectric to sweep.
Cons:
Earthquake.
Heracross
http://smogon.com/dp/pokemon/heracross
Dream World Ability: Overconfidence
Ability Characteristics:
The pokemon's attack rises one stage when it KOs an opposing pokemon.
Pros:
Although Heracross' attack was already very high, this new ability raises it even higher, and when coupled with its dual base 120 STAB moves, Heracross can become a formidable enemy. You can't just sacrifice a weak pokemon to its assault, because it will just get an attack boost and severaly damage your counter.
Cons:
Heracross loses Guts, which was a very important ability on him. Cross had a tendency to need a Choice item to do its work well, so Overconfidence may not work well if the opponent sends out a ghost type and Hera is locked into one of its STAB moves. Guts worked well when coupled with a Toxic Orb, as it allowed Cross to absorb status and deal massive damage. With Heracross' low speed, Overconfidence may not be the beset ability for him.
Breloom
http://smogon.com/dp/pokemon/breloom
Dream World Ability: Technician
Ability Characteristics:
Moves with base power 60 or lower recieve a 50% boost.
Pros:
Breloom's Mach Punch hits as hard as Scizor's Bullet Punch, but with fewer resistances. That alone should make it viable. But with access to a 120 BP Drain Punch, boosted Bullet Seed to hit through subs, and Spore, Breloom can serve as an excellent revenge killer and bulky attacker.
Cons:
Without Poison Heal, Breloom is no longer immune to status and doesn't regain the 12% health every turn, so it may die much mre quickly than a standard Breloom.
Gliscor
http://smogon.com/dp/pokemon/gliscor
Dream World Ability: Poison Heal
Ability Characteristics:
When this pokemon is poisoned, it heals 1/8 of its max HP at the end of each turn instead of taking damage.
Pros:
Gliscor recovers health twice as fast as before, and gains an immunity to poison that could otherwise end its reign of terror. This new ability allows it stall for an amazingly long time, all the while hitting hard with STAB Earthquakes.
Cons:
It loses Sand Veil, which allowed it to stall out many opponents with Roost until they missed and Toxic them to death. Also, it loses Roost if it chooses Poison Heal, which decreases its tanking ability tremendously. In fact, because of the loss of Roost, the ability may be useless.
Swampert
http://smogon.com/dp/pokemon/swampert
Dream World Ability: Damp
Ability Characteristics:
If a Pokémon uses Self Destruct or Explosion while this Pokémon is out, it will fail. While a Pokémon with this ability is in battle, damage from Aftermath is prevented.
Pros:
This ability makes Swampert an excellent anti-lead, stopping Explosion and setting up Stealth Rock. Damp also allows Swampert to fully stop any non-boosting physical sweeper and Roar them out; pokemon will no longer be able to explode on it and remove it. However, with the nerf Explosion got in Gen V, not halving the opponent's defense, this ability isn't as useful as it would be. However, if Swampert is at low health, it will appreciate the protection from Explosion.
Cons:
Swampert loses Torrent, but it never used that anyway.
Politoed
http://smogon.com/dp/pokemon/politoed
Dream World Ability: Drizzle
Ability Characteristics:
When this Pokémon is brought out, a permanent rain covers the battlefield.
Pros:
Politoed can setup everlasting rain for rain sweepers, allowing for much easier Swift Swim abuse and boosted Water attacks. Water Attacks also hit SE against Drought Ninetales and Tyranitar switching in, so it is not so easily stopped.
Cons:
It loses Water Absorb, which was pretty useful, but the offensive power of everlasting rain far outweighs Poli's special walling abilities.
Vaporeon
http://smogon.com/dp/pokemon/vaporeon
Dream World Ability: Hydration
Ability Characteristics:
Heals all status effects at the end of the turn if Rain is active.
Pros:
Vaporeon can now use Rest along with Hydration to restore all of its health, instead of using Wish + Protect. This allows for another moveslot, and also heals it of any status it may have. Because of Politoed's Drizzle, Vaporeon doesn't have to rely on the 8-turn max Rain Dance.
Cons:
It loses Water Absorb, which was one of its best qualities, allowing it to stall out other waters and giving it free health. However, it does get full health from Rest, which offsets the loss of the immunity somewhat.
Tentacruel
http://smogon.com/dp/pokemon/tentacruel
Dream World Ability: Rain Dish
Ability Characteristics:
Heals 1/16 max HP in rain.
Pros:
Tentacruel is a staple on full stall teams, laying and absorbing Toxic Spikes, while providing a solid Infernape (and now Blaziken) check. But with rain up, it can heal 12% HP per turn. This allows Tentacruel to stall for much longer, and provide more utility than simply laying Toxic Spikes.
Cons:
Unless you use a SD Tentacruel, Clear Body does nothing for it, while Rain Dish helps it tremendously.
Venusaur
http://smogon.com/dp/pokemon/venusaur
Dream World Ability: Chlorophyll
Ability Characteristics:
Sun doubles the Speed of Pokémon with Chlorophyll.
Pros:
Venusaur, while being bulky enough to withstand UU assaults throughout Gen IV, never had the ability to do well in OU due to its low speed. With Chlorophyll, this issue is solved, and Venusaur becomes an incredibly fast threat that can put a counter to sleep with Sleep Powder. With access to powerful STAB moves like Power Whip and Leaf Storm, Venusaur has the potential to be a top-tier attacker.
Cons:
Venusaur loses Overgrow, but it didn't use that much, due to its poor speed.
Raikou
http://smogon.com/dp/pokemon/sharpedo
Dream World Ability: Volt Absorb
Ability Characteristics:
Restores up to 25% health when hit by an electric type attack.
Pros:
Raikou now has more opportunities to switch in and heal off previous damage. This gives Raikou an excellent advantage over Starmie, being able to switch into and heal off of electric attacks. Raikou is also bulkier than Starmie and can utilize Choice Specs to hit hard, without a Pursuit weakness, and with Volt Absorb replenishing its health if it switches in on the right attack.
Cons:
Raikou never could run a good defensive set, so it doesn't care about losing Pressure.
Sharpedo
http://smogon.com/dp/pokemon/sharpedo
Dream World Ability: Speed Boost
Ability Characteristics:
This pokemon's speed is boosted one stage at the end of every turn.
Pros:
Sharpedo now gets excellent speed to match its excellent offenses. With 95 speed, Sharpedo was vulnerable to getting revenge killed by a Scarfer or just something faster. Now, with speed boost, it can outspeed and KO these threats.
Cons:
Rough Skin was useful to kill Flailers/Reversalers, but any priority can kill those anyway. And speed boost along with Endure/Protect allows Sharpedo to outspeed and KO those 1 HP sweepers.
Pikachu
http://smogon.com/dp/pokemon/pikachu
Dream World Ability: Lightningrod
Ability Characteristics:
If the pokemon is hit with an electric move, its special attack rises 1 stage.
Pros:
Light Ball Pikachu just became that much more deadly now that he's boasting close to 600 Special Attack. With Electric being a common attack, he'll find a lot of opportunities to switch in, sub up, and launch super powerful Thunderbolts.
Cons:
Because of Pikachu's low speed and defenses, it will still die very easily.
Zapdos
http://smogon.com/dp/pokemon/zapdos
Dream World Ability: Lightningrod
Ability Characteristics:
If the pokemon is hit with an electric move, its special attack rises 1 stage.
Pros:
Zapdos' 125 base special attack looks a lot more threatening with a +1 boost. The ability to fire off hugely powerful STAB Thunderbolts is very dangerous, and when coupled with Life Orb or Choice Specs it gets that much worse, especially considering its access to Roost to recover from recoil and Agility to outspeed nearly everything.
Cons:
Pressure is overwhelmingly the better ability on defensive sets: Zapdos is a very bulky pokemon, and can make a sturdy wall with Roost and Pressure. But for offense, Lightningrod is the clear choice.
Lapras
http://smogon.com/dp/pokemon/lapras
Dream World Ability: Hydration
Ability Characteristics:
When Rain Dance is in effect, this Pokémon heals itself of burn, freeze, paralysis, poison, and sleep at the end of each turn.
Pros:
Lapras can now become a sturdy, status-free tank in the rain, or use a DD + HydraRest set to heal off damage and DD up to sweep.
Cons:
Lapras did enjoy Water Absorb, but HydraRest makes up for that loss, and works much better with Dragon Dance.
Lickilicky
http://smogon.com/dp/pokemon/lickilicky
Dream World Ability: Cloud Nine
Ability Characteristics:
While a Pokémon with Cloud Nine is in play, the effects of weather are temporarily disabled.
Pros:
Lickilicky's good bulk and attack allow it to effectively slow down weather teams, which are much more potent with Drought Ninetales and Drizzle Politoed available. Cloud Nine lets it stop the weather that threatens to sweep your team and even setup on weaker rain sweepers.
Cons:
Losing Own Tempo leaves it susceptible to confusion, but due to confusion's low usage, Lickilicky won't be losing much.
Salamence
http://smogon.com/dp/pokemon/salamence
Dream World Ability: Overconfidence
Ability Characteristics:
This pokemon gains a +1 attack boost after KOing an opponent.
Pros:
Salamence was already voted Uber in Gen IV for its amazing power after a DD, and this ability just makes it better. Many times, one would switch in a pokemon to take Mence's attack and die just to get a free switch in for their check. But with Overconfidence, Mence will just get stronger and potentially sweep your team. Mixmence will also benefit from this ability; although it can't switch in as easily as with Intimidate, its boosted moves can deal excellent damage to the opponent.
Cons:
The loss of Outrage really hurts Salamence, as it is no longer a tutor move in Black and White. Unless it gets it via breeding, Salamence will have no choice but to resort to the inferior Dragon Claw. Also, Salamence will be harder to switch in thanks to the loss of Intimidate.
Poliwrath
http://smogon.com/dp/pokemon/poliwrath
Dream World Ability: Swift Swim
Ability Characteristics:
This pokemon's speed doubles in rain.
Pros:
Pros: With access to Belly Drum and Bulk Up, Poliwrath can now boost his attack to astronomical heights all the while having boosted speed as well in the what is soon to be common rain. Two great STABs grant nearly flawless coverage and his 90/95/90 defenses aren't to be taken lightly either. Resistances to Rock, Water, Dark, Ice, Bug, Ghost, and Steel will allow him to switch in quite easily and setup.
Cons:
Losing Water Absorb doesn't allow him to switch into water attacks as easily, but he still resists them and has decent Special Defense, so it's not much of a problem.
Mamoswine
http://smogon.com/dp/pokemon/mamoswine
Dream World Ability: Thick Fat
Ability Characteristics:
When this Pokémon is damaged by an Ice- or Fire-type attack, it takes 50% of the damage it would have taken.
Pros:
Mamoswine was never able to take advantage of Snow Cloak very well, and Thick Fat removes its weakness to Fire, allowing it to to do its job as a bulky attacker much better.
Cons:
Snow Cloak was practically useless on him, so Mamoswine hasn't lost anything significant.
Sceptile
http://smogon.com/dp/pokemon/sceptile
Dream World Ability: Unburden
Ability Characteristics:
When a Pokémon with this ability consumes an item or has one removed from it (for example, by Trick, Knock Off, Bug Bite, Fling, or Natural Gift) its Speed is doubled until it switches out.
Pros:
Although it was fast already, Unburden allows Sceptile to outspeed literally everything, including scarfers. This allows it to sweep without fear of being revenge killed except by priority. It can easily become a very threatening sweeper with a SubLiechi+Swords Dance set.
Cons:
It loses its ability to hit with boosted Grass attacks at low health, which allowed it to run a good SubSD+Liechi set, but due to Grass' poor coverage, it could never really take advantage of it.
Crawdaunt
http://smogon.com/dp/pokemon/crawdaunt
Dream World Ability: Adaptability
Ability Characteristics:
The STAB modifier of the user becomes x2 instead of x1.5.
Pros:
With Rain becoming even more powerful and Crabhammer's boost to 90 accuracy, Crawdaunt makes great use of his monstrous attack with Adaptability. He can now be a terror in the hit-and-run game with a Choice Band, or he can stay and fight with Swords Dance, boosting his offensive prowess to godly levels. Crunch is also boosted, giving him a viable secondary STAB.
Cons:
Crawdaunt can now lose his attack from Intimidate, but the huge power of Adaptibility makes up for any Intimidate he might receive.
Leafeon
http://smogon.com/dp/pokemon/leafeon
Dream World Ability: Chlorophyll
Ability Characteristics:
Speed doubles in sun.
Pros:
Leafeon is a solid supporter, with its excellent physical bulk and good attack, but this ability allows it to outpace the faster pokemon that often ruin its attempts at a sweep. But with Swords Dance and Chlorophyll, Leafeon can make for an excellent physical sweeper, although it is still walled horribly by Steels.
Cons:
Leafeon loses Leaf Guard, which helped the supporter sets a bit, but for sweeping sets, Chlorophyll works much better.
Gyarados
http://smogon.com/dp/pokemon/gyarados
Dream World Ability: Overconfidence
Ability Characteristics:
The pokemon's attack rises one stage after it KOs an opponent.
Pros:
Dragon Dance Gyarados was an excellent sweeper in Gen IV, and this new ability allows it to sweep even more effectively. If it gets even one KO, it becomes a much bigger threat than it was before.
Cons:
Gyarados can't take hits like it used to and can't run a bulky set as effectively as a set with Intimidate, so this ability only really helps the all-out offensive sets.
Ho-Oh
http://smogon.com/dp/pokemon/ho-oh
Dream World Ability: Regeneration
Ability Characteristics:
This pokemon recovers 30% HP upon switching out.
Pros:
Ho-Oh's quadruple weakness to Stealth Rock often only gave it a single attempt at a sweep. With Regeneration, however, it can recover back a good amount of that health upon switching out, so it has a chance at sweeping again if it has over 20% health upon switching out.
Cons:
Ho-Oh loses the ability to Pressure stall its opponents, but considering its tendency to go on all-out offense, Pressure doesn't help it that much.
Slowbro
http://smogon.com/dp/pokemon/slowbro
Dream World Ability: Regeneration
Ability Characteristics:
This pokemon recovers 30% HP upon switching out.
Pros:
Slowbro, already an excellent physical wall, becomes even better with Regeneration. Most walls need to keep their health up upon switching out, to be able to take damage when they switch back in. Slowbro has Slack off, but losing a turn to let the opponent switch in something that threatens it is always bad. But with Regeneration, it doesn't need to care as much about being healthy upon switching out, as it gains 30% immediately. This lets Slowbro switch in more and stall out the opponent much more efficiently.
Cons:
Own Tempo helped with switching into Machamp, allowing Slowbro to hit it hard or status it, but due to confusion's low usage, Regeneration is much more useful.
Tangrowth
http://smogon.com/dp/pokemon/tangrowth
Dream World Ability: Regeneration
Ability Characteristics:
This pokemon recovers 30% HP upon switching out.
Pros:
Tangrowth, although it possesses excellent Defense and good attacking stats, is usually outclassed as a wall due to lack of reliable healing and horrible Special defense. While the latter can't be fixed, Regeneration helps tremendously with the first; Tangrowth can sponge an attack and switch out, healing 30% from Regeneration. This allows Tangrowth to become a much more effective wall.
Cons:]
Although Leaf Guard helps, as a tank it's not really very useful except for blocking Toxic. Chlorophyll only helps with attacking sets, and defensive sets like Regeneration much more.
Lucario
http://smogon.com/dp/pokemon/lucario
Dream World Ability: Justice Heart
Ability Characteristics:
This pokemon rises one stage in attack when hit by a Dark type move.
Pros:
Although Lucario liked not being flinched, an extra stage of attack lets it hit even harder than it already does. SD Lucario would become even more potent than it already was, OHKOing Hippowdon with Close Combat and doing around 70% to Gliscor with Extremespeed, KOing it after some residual damage. It could also utilize its new move Cheer Up and the attack boost and become an excellent mixed sweeper.
Cons:
Not being able to be flinched allowed it run through Choice Scarf Jirachi with Close Combat, but had little utility outside of that.
Typhlosion
http://smogon.com/dp/pokemon/typhlosion
Dream World Ability: Flash Fire
Ability Characteristics:
Grants immunity to Fire-type moves and increases the power of Fire-type moves by 50% when hit by a Fire-type move.
Pros:
Choice Scarf Typhlosion just became a lot scarier. With access to Eruption and Flash Fire, Typhlosion can launch double STAB Eruptions and outrun almost all non-boosted pokemon if it comes in on a Fire attack. Alternatively, one could use Choice Specs to utterly annihilate anything in its path, but then its speed is pretty mediocre.
Cons:
Blaze allows Typhlosion to repeatedly use double STAB boosted Fire attacks, but only when it gets low on health, so it can't use a boosted Eruption like Flash Fire can.
Dragonite
http://smogon.com/dp/pokemon/dragonite
Dream World Ability: Multi-Scale
Ability Characteristics:
When this pokemon is at full HP, damage is lessened.
Pros:
Dragonite can now take the role of a defensive dragon much more easily; it can switch into many more attacks without much fear. Along with Roost, Dragonite can turn into an excellent tank that can take a lot of hits. However, offensive sets benefit too. Multi-Scale basically gives it a free turn to setup a DD and sweep.
Cons:
Inner Focus helps a lot with a lead set, allowing it to defeat Jirachi leads and take less damage from Infernape leads, but Multi-Scale can help with other leads that have powerful attacks.
Ditto
http://smogon.com/dp/pokemon/ditto
Dream World Ability: Eccentric
Ability Characteristics:
When Ditto switches in, it automatically changes into the opponent's pokemon, with Ditto's HP.
Pros:
Equipped with a Choice Scarf, Ditto now makes an absolutely top-tier revenge killer. As it switches in, it copies the opponent's stats and stat changes. Since Ditto will have the same stats as the pokemon, and have a Choice Scarf, it will outspeed and KO the boosted sweeper with their own elevated stats. Ditto's new ability provides a great new way to revenge such dangerous sweepers as Overconfidence Gyarados and Speed Boost Blaziken.
Cons:
Ditto loses Limber, but that wasn't helping it much anyway. Eccentric simply allows it to use Transform (its only move) more quickly.
Nidoking
http://smogon.com/dp/pokemon/nidoking
Dream World Abiltiy: Encourage
Ability Characteristics:
Encourage increases the attack power of moves with secondary effects by 50% but prevents said effects from occurring.
Pros:
Nidoking has never quite been OU material. He has lackluster 92 attack and 85 special attack. Despite his large move pool, he just doesn't have the oomph needed to play with the big boys. Now that Encourage adds some power to his attacks, the king just might have what it takes.
Almost every move that Nidoking would use for his standard sets is powered by Encourage, giving them a STAB boost. All the important moves that receive a boost are as follows: Earth Power, Fire Blast, Flamethrower, Focus Blast, Ice Beam, Poison Jab, Sludge Bomb, Shadow Ball, Thunder, Thunderbolt, and the three elemental punches. That's quite a resume. Notably, Sludge Bomb and Earth Power have a 202 BP and Poison Jab will have a 180 BP.
Cons:
Most likely, a simple pseudo-STAB boost won't be enough to help Nidoking. He has more problems besides low attack stats. At best Encourage will make Nidoking a premier UU wall breaker that gets bumped to BL, but even that is wishful thinking. More likely, he will solidify a place in upper UU usage as a mixed sweeper/wall breaker. It doesn't lose any good abilities: Poison point is a terrible ability and why use the luck based Rivalry when you can have a guaranteed boost from Encourage.
Espeon
http://smogon.com/dp/pokemon/espeon
Dream World Ability: Magic Mirror
Ability Characteristics:
Reflects status back at the user. Also reflects entry hazards.
Pros:
There's no doubt that this is an amazing ability. With Magic Mirror, Espeon might finally have that edge over Alakazam it's been waiting for. With its excellent special attack and ability to reflect both status and Entry Hazards, it makes a great switch-in to almost any wall. It can also run a viable lead set, not letting the opponent setup hazards, although its lack of priority is disappointing. Espeon has an advantage over Alakazam in that it doesn't have to worry about paralysis, which cripples Alakazam.
Cons:
Although Synchronize was nice, the pokemon trying to paralyze Espy aren't usually fast, and so paralysis doesn't really help, and it ruins plans of poisoning the bulky walls that tend to use Thunder Wave. Magic Mirror reflects the status back, baking it infinitely better than Synchronize.
Lugia
http://smogon.com/dp/pokemon/lugia
Dream World Ability: Multi-Scale
Ability Characteristics:
Reduces damage taken when pokemon is at full health.
Pros:
While Lugia is already an excellent wall, Multi-Scale allows it to take even less damage from attackers that might try to scratch its mighty bulk. If Stealth Rock is off the field, Lugia can take a +2 Stone Edge from the standard RP Groudon and setup a Reflect, letting it halt Groudon's sweep. It also takes a paltry 31.7% - 37.5% from a nonboosted Stone Edge if it's at full health, letting it fully halt Groudon's rampage with Reflect and Roost off any damage taken.
Cons:
Lugia now loses the ability to Pressure stall its opponents. However, considering Lugia's use as a wall against physical sweepers, this ability isn't very useful. Also, Stealth Rock needs to be off of the field to have Multi-Scale activate, so a spinner is absolutely necessary to utilize this ability.
Thanks for reading, and don't be afraid to tell me how wrong I am. I appreciate any help you guys could give me.
Blaziken
http://www.smogon.com/dp/pokemon/blaziken
Dream World Ability: Speed Boost
Ability Characteristics:
This Pokémon's Speed is boosted one stage at the end of each turn.
Pros:
Blaziken, while being a powerful sweeper, has been relegated to UU all throughout D/P because of its low speed. However, with Speed Boost, it can utilize its high attacking stats while boosting its speed to become a fearsome sweeper. Coupled with the now boosted Hi Jump Kick, a 135 base power STAB move, Blaziken has the potential to wreck teams all on its own.
Cons:
Blaziken loses Blaze, but that was only useful for Endure+Reversal or pinch berry sets. Speed Boost helps with both of those, allowing it to go faster than enemies trying to revenge kill it while it's at low health.
Staraptor
http://www.smogon.com/dp/pokemon/staraptor
Dream World Ability: Reckless
Ability Characteristics:
Moves with recoil gain a 20% boost.
Pros:
LO Staraptor just got a lot more deadly; Brave Bird and Double-Edge's base power is effectively 216, factoring in STAB. With Close Combat hitting many of the pokemon that resist them SE, Staraptor could also become an excellent Choice Bander. Its good base 100 speed also allows it to sweep against a slower team.
Cons:
Unfortunately, Staraptor loses Intimidate, which helped it to switch in much more easily, but with the huge power of Reckless Brave Bird/Double Edge, once it gets in, the opponent will be hard-pressed to find a good switch-in. However, Reckless recoil and Life Orb will wear down its health very quickly, so it will have problems taking even one hit.
Ninetales
http://www.smogon.com/dp/pokemon/ninetales
Dream World Ability: Drought
Ability Characteristics:
When this Pokémon is brought out, a permanent sun covers the battlefield.
Pros:
A sun team's best friend. With unlimited Sunny Day, sun teams could become a bit more viable. Without a turn needed to setup, a Ninetales lead could use an Escape Button to immediately get in a sweeper scot-free. Things like Jumpluff could finally get some use in OU because of this great ability.
Cons:
Ninetales was never able to abuse Flash Fire well, and Drought allows it to setup a whole team.
Alakazam
http://www.smogon.com/dp/pokemon/alakazam
Dream World Ability: Magic Guard
Ability Characteristics:
This pokemon takes no indirect damage.
Pros:
This is huge for Alakazam; it mostly used a Life Orb or Choice Specs set in UU to wreck stuff with its great special attack. Magic Guard negates Life Orb recoil, allowing Alakazam to attack without fear of KOing itself. But Magic Guard also removes entry hazard damage, allowing the Choice Specs set to switch in and out much more easily after hitting hard with its boosted attacks.
Cons:
Alakazam loses Synchronize, which could be useful to paralyze the pokemon paralyzing it, but Substitute mostly mitigated that threat.
Hitmonlee
http://smogon.com/dp/pokemon/hitmonlee
Dream World Ability: Unburden
Ability Characteristics:
The user's speed doubles after losing its item.
Pros:
Hitmonlee could utilize this along with a pinch berry to boost its attack and double its speed in a single turn by using Substitute or Endure. With access to the now 135 BP Hi Jump Kick, Hitmonlee could become an insanely fast and strong sweeper, only susceptible to priority moves and Hail/Sandstorm.
Cons:
It loses Limber, but the offensive utility of Unburden far outclasses the ability to switch in on Thunder Wave.
Ampharos and Manectric
http://smogon.com/dp/pokemon/ampharos
http://smogon.com/dp/pokemon/manectric
Dream World Ability: Plus and Minus
Ability Characteristics:
The pokemon's special attack increases 50% when on the field with a pokemon with the opposite sign ability.
Pros:
Manectric and Ampharos, while not extremely useful on their own, can become a potent duo when paired with Plus and Minus. Manectric's great speed and special attacking movepool, along with the Minus boost, allow it to bring on the hurt in doubles, while Ampharos' good bulk and great supporting movepool let it help Manectric to sweep.
Cons:
Earthquake.
Heracross
http://smogon.com/dp/pokemon/heracross
Dream World Ability: Overconfidence
Ability Characteristics:
The pokemon's attack rises one stage when it KOs an opposing pokemon.
Pros:
Although Heracross' attack was already very high, this new ability raises it even higher, and when coupled with its dual base 120 STAB moves, Heracross can become a formidable enemy. You can't just sacrifice a weak pokemon to its assault, because it will just get an attack boost and severaly damage your counter.
Cons:
Heracross loses Guts, which was a very important ability on him. Cross had a tendency to need a Choice item to do its work well, so Overconfidence may not work well if the opponent sends out a ghost type and Hera is locked into one of its STAB moves. Guts worked well when coupled with a Toxic Orb, as it allowed Cross to absorb status and deal massive damage. With Heracross' low speed, Overconfidence may not be the beset ability for him.
Breloom
http://smogon.com/dp/pokemon/breloom
Dream World Ability: Technician
Ability Characteristics:
Moves with base power 60 or lower recieve a 50% boost.
Pros:
Breloom's Mach Punch hits as hard as Scizor's Bullet Punch, but with fewer resistances. That alone should make it viable. But with access to a 120 BP Drain Punch, boosted Bullet Seed to hit through subs, and Spore, Breloom can serve as an excellent revenge killer and bulky attacker.
Cons:
Without Poison Heal, Breloom is no longer immune to status and doesn't regain the 12% health every turn, so it may die much mre quickly than a standard Breloom.
Gliscor
http://smogon.com/dp/pokemon/gliscor
Dream World Ability: Poison Heal
Ability Characteristics:
When this pokemon is poisoned, it heals 1/8 of its max HP at the end of each turn instead of taking damage.
Pros:
Gliscor recovers health twice as fast as before, and gains an immunity to poison that could otherwise end its reign of terror. This new ability allows it stall for an amazingly long time, all the while hitting hard with STAB Earthquakes.
Cons:
It loses Sand Veil, which allowed it to stall out many opponents with Roost until they missed and Toxic them to death. Also, it loses Roost if it chooses Poison Heal, which decreases its tanking ability tremendously. In fact, because of the loss of Roost, the ability may be useless.
Swampert
http://smogon.com/dp/pokemon/swampert
Dream World Ability: Damp
Ability Characteristics:
If a Pokémon uses Self Destruct or Explosion while this Pokémon is out, it will fail. While a Pokémon with this ability is in battle, damage from Aftermath is prevented.
Pros:
This ability makes Swampert an excellent anti-lead, stopping Explosion and setting up Stealth Rock. Damp also allows Swampert to fully stop any non-boosting physical sweeper and Roar them out; pokemon will no longer be able to explode on it and remove it. However, with the nerf Explosion got in Gen V, not halving the opponent's defense, this ability isn't as useful as it would be. However, if Swampert is at low health, it will appreciate the protection from Explosion.
Cons:
Swampert loses Torrent, but it never used that anyway.
Politoed
http://smogon.com/dp/pokemon/politoed
Dream World Ability: Drizzle
Ability Characteristics:
When this Pokémon is brought out, a permanent rain covers the battlefield.
Pros:
Politoed can setup everlasting rain for rain sweepers, allowing for much easier Swift Swim abuse and boosted Water attacks. Water Attacks also hit SE against Drought Ninetales and Tyranitar switching in, so it is not so easily stopped.
Cons:
It loses Water Absorb, which was pretty useful, but the offensive power of everlasting rain far outweighs Poli's special walling abilities.
Vaporeon
http://smogon.com/dp/pokemon/vaporeon
Dream World Ability: Hydration
Ability Characteristics:
Heals all status effects at the end of the turn if Rain is active.
Pros:
Vaporeon can now use Rest along with Hydration to restore all of its health, instead of using Wish + Protect. This allows for another moveslot, and also heals it of any status it may have. Because of Politoed's Drizzle, Vaporeon doesn't have to rely on the 8-turn max Rain Dance.
Cons:
It loses Water Absorb, which was one of its best qualities, allowing it to stall out other waters and giving it free health. However, it does get full health from Rest, which offsets the loss of the immunity somewhat.
Tentacruel
http://smogon.com/dp/pokemon/tentacruel
Dream World Ability: Rain Dish
Ability Characteristics:
Heals 1/16 max HP in rain.
Pros:
Tentacruel is a staple on full stall teams, laying and absorbing Toxic Spikes, while providing a solid Infernape (and now Blaziken) check. But with rain up, it can heal 12% HP per turn. This allows Tentacruel to stall for much longer, and provide more utility than simply laying Toxic Spikes.
Cons:
Unless you use a SD Tentacruel, Clear Body does nothing for it, while Rain Dish helps it tremendously.
Venusaur
http://smogon.com/dp/pokemon/venusaur
Dream World Ability: Chlorophyll
Ability Characteristics:
Sun doubles the Speed of Pokémon with Chlorophyll.
Pros:
Venusaur, while being bulky enough to withstand UU assaults throughout Gen IV, never had the ability to do well in OU due to its low speed. With Chlorophyll, this issue is solved, and Venusaur becomes an incredibly fast threat that can put a counter to sleep with Sleep Powder. With access to powerful STAB moves like Power Whip and Leaf Storm, Venusaur has the potential to be a top-tier attacker.
Cons:
Venusaur loses Overgrow, but it didn't use that much, due to its poor speed.
Raikou
http://smogon.com/dp/pokemon/sharpedo
Dream World Ability: Volt Absorb
Ability Characteristics:
Restores up to 25% health when hit by an electric type attack.
Pros:
Raikou now has more opportunities to switch in and heal off previous damage. This gives Raikou an excellent advantage over Starmie, being able to switch into and heal off of electric attacks. Raikou is also bulkier than Starmie and can utilize Choice Specs to hit hard, without a Pursuit weakness, and with Volt Absorb replenishing its health if it switches in on the right attack.
Cons:
Raikou never could run a good defensive set, so it doesn't care about losing Pressure.
Sharpedo
http://smogon.com/dp/pokemon/sharpedo
Dream World Ability: Speed Boost
Ability Characteristics:
This pokemon's speed is boosted one stage at the end of every turn.
Pros:
Sharpedo now gets excellent speed to match its excellent offenses. With 95 speed, Sharpedo was vulnerable to getting revenge killed by a Scarfer or just something faster. Now, with speed boost, it can outspeed and KO these threats.
Cons:
Rough Skin was useful to kill Flailers/Reversalers, but any priority can kill those anyway. And speed boost along with Endure/Protect allows Sharpedo to outspeed and KO those 1 HP sweepers.
Pikachu
http://smogon.com/dp/pokemon/pikachu
Dream World Ability: Lightningrod
Ability Characteristics:
If the pokemon is hit with an electric move, its special attack rises 1 stage.
Pros:
Light Ball Pikachu just became that much more deadly now that he's boasting close to 600 Special Attack. With Electric being a common attack, he'll find a lot of opportunities to switch in, sub up, and launch super powerful Thunderbolts.
Cons:
Because of Pikachu's low speed and defenses, it will still die very easily.
Zapdos
http://smogon.com/dp/pokemon/zapdos
Dream World Ability: Lightningrod
Ability Characteristics:
If the pokemon is hit with an electric move, its special attack rises 1 stage.
Pros:
Zapdos' 125 base special attack looks a lot more threatening with a +1 boost. The ability to fire off hugely powerful STAB Thunderbolts is very dangerous, and when coupled with Life Orb or Choice Specs it gets that much worse, especially considering its access to Roost to recover from recoil and Agility to outspeed nearly everything.
Cons:
Pressure is overwhelmingly the better ability on defensive sets: Zapdos is a very bulky pokemon, and can make a sturdy wall with Roost and Pressure. But for offense, Lightningrod is the clear choice.
Lapras
http://smogon.com/dp/pokemon/lapras
Dream World Ability: Hydration
Ability Characteristics:
When Rain Dance is in effect, this Pokémon heals itself of burn, freeze, paralysis, poison, and sleep at the end of each turn.
Pros:
Lapras can now become a sturdy, status-free tank in the rain, or use a DD + HydraRest set to heal off damage and DD up to sweep.
Cons:
Lapras did enjoy Water Absorb, but HydraRest makes up for that loss, and works much better with Dragon Dance.
Lickilicky
http://smogon.com/dp/pokemon/lickilicky
Dream World Ability: Cloud Nine
Ability Characteristics:
While a Pokémon with Cloud Nine is in play, the effects of weather are temporarily disabled.
Pros:
Lickilicky's good bulk and attack allow it to effectively slow down weather teams, which are much more potent with Drought Ninetales and Drizzle Politoed available. Cloud Nine lets it stop the weather that threatens to sweep your team and even setup on weaker rain sweepers.
Cons:
Losing Own Tempo leaves it susceptible to confusion, but due to confusion's low usage, Lickilicky won't be losing much.
Salamence
http://smogon.com/dp/pokemon/salamence
Dream World Ability: Overconfidence
Ability Characteristics:
This pokemon gains a +1 attack boost after KOing an opponent.
Pros:
Salamence was already voted Uber in Gen IV for its amazing power after a DD, and this ability just makes it better. Many times, one would switch in a pokemon to take Mence's attack and die just to get a free switch in for their check. But with Overconfidence, Mence will just get stronger and potentially sweep your team. Mixmence will also benefit from this ability; although it can't switch in as easily as with Intimidate, its boosted moves can deal excellent damage to the opponent.
Cons:
The loss of Outrage really hurts Salamence, as it is no longer a tutor move in Black and White. Unless it gets it via breeding, Salamence will have no choice but to resort to the inferior Dragon Claw. Also, Salamence will be harder to switch in thanks to the loss of Intimidate.
Poliwrath
http://smogon.com/dp/pokemon/poliwrath
Dream World Ability: Swift Swim
Ability Characteristics:
This pokemon's speed doubles in rain.
Pros:
Pros: With access to Belly Drum and Bulk Up, Poliwrath can now boost his attack to astronomical heights all the while having boosted speed as well in the what is soon to be common rain. Two great STABs grant nearly flawless coverage and his 90/95/90 defenses aren't to be taken lightly either. Resistances to Rock, Water, Dark, Ice, Bug, Ghost, and Steel will allow him to switch in quite easily and setup.
Cons:
Losing Water Absorb doesn't allow him to switch into water attacks as easily, but he still resists them and has decent Special Defense, so it's not much of a problem.
Mamoswine
http://smogon.com/dp/pokemon/mamoswine
Dream World Ability: Thick Fat
Ability Characteristics:
When this Pokémon is damaged by an Ice- or Fire-type attack, it takes 50% of the damage it would have taken.
Pros:
Mamoswine was never able to take advantage of Snow Cloak very well, and Thick Fat removes its weakness to Fire, allowing it to to do its job as a bulky attacker much better.
Cons:
Snow Cloak was practically useless on him, so Mamoswine hasn't lost anything significant.
Sceptile
http://smogon.com/dp/pokemon/sceptile
Dream World Ability: Unburden
Ability Characteristics:
When a Pokémon with this ability consumes an item or has one removed from it (for example, by Trick, Knock Off, Bug Bite, Fling, or Natural Gift) its Speed is doubled until it switches out.
Pros:
Although it was fast already, Unburden allows Sceptile to outspeed literally everything, including scarfers. This allows it to sweep without fear of being revenge killed except by priority. It can easily become a very threatening sweeper with a SubLiechi+Swords Dance set.
Cons:
It loses its ability to hit with boosted Grass attacks at low health, which allowed it to run a good SubSD+Liechi set, but due to Grass' poor coverage, it could never really take advantage of it.
Crawdaunt
http://smogon.com/dp/pokemon/crawdaunt
Dream World Ability: Adaptability
Ability Characteristics:
The STAB modifier of the user becomes x2 instead of x1.5.
Pros:
With Rain becoming even more powerful and Crabhammer's boost to 90 accuracy, Crawdaunt makes great use of his monstrous attack with Adaptability. He can now be a terror in the hit-and-run game with a Choice Band, or he can stay and fight with Swords Dance, boosting his offensive prowess to godly levels. Crunch is also boosted, giving him a viable secondary STAB.
Cons:
Crawdaunt can now lose his attack from Intimidate, but the huge power of Adaptibility makes up for any Intimidate he might receive.
Leafeon
http://smogon.com/dp/pokemon/leafeon
Dream World Ability: Chlorophyll
Ability Characteristics:
Speed doubles in sun.
Pros:
Leafeon is a solid supporter, with its excellent physical bulk and good attack, but this ability allows it to outpace the faster pokemon that often ruin its attempts at a sweep. But with Swords Dance and Chlorophyll, Leafeon can make for an excellent physical sweeper, although it is still walled horribly by Steels.
Cons:
Leafeon loses Leaf Guard, which helped the supporter sets a bit, but for sweeping sets, Chlorophyll works much better.
Gyarados
http://smogon.com/dp/pokemon/gyarados
Dream World Ability: Overconfidence
Ability Characteristics:
The pokemon's attack rises one stage after it KOs an opponent.
Pros:
Dragon Dance Gyarados was an excellent sweeper in Gen IV, and this new ability allows it to sweep even more effectively. If it gets even one KO, it becomes a much bigger threat than it was before.
Cons:
Gyarados can't take hits like it used to and can't run a bulky set as effectively as a set with Intimidate, so this ability only really helps the all-out offensive sets.
Ho-Oh
http://smogon.com/dp/pokemon/ho-oh
Dream World Ability: Regeneration
Ability Characteristics:
This pokemon recovers 30% HP upon switching out.
Pros:
Ho-Oh's quadruple weakness to Stealth Rock often only gave it a single attempt at a sweep. With Regeneration, however, it can recover back a good amount of that health upon switching out, so it has a chance at sweeping again if it has over 20% health upon switching out.
Cons:
Ho-Oh loses the ability to Pressure stall its opponents, but considering its tendency to go on all-out offense, Pressure doesn't help it that much.
Slowbro
http://smogon.com/dp/pokemon/slowbro
Dream World Ability: Regeneration
Ability Characteristics:
This pokemon recovers 30% HP upon switching out.
Pros:
Slowbro, already an excellent physical wall, becomes even better with Regeneration. Most walls need to keep their health up upon switching out, to be able to take damage when they switch back in. Slowbro has Slack off, but losing a turn to let the opponent switch in something that threatens it is always bad. But with Regeneration, it doesn't need to care as much about being healthy upon switching out, as it gains 30% immediately. This lets Slowbro switch in more and stall out the opponent much more efficiently.
Cons:
Own Tempo helped with switching into Machamp, allowing Slowbro to hit it hard or status it, but due to confusion's low usage, Regeneration is much more useful.
Tangrowth
http://smogon.com/dp/pokemon/tangrowth
Dream World Ability: Regeneration
Ability Characteristics:
This pokemon recovers 30% HP upon switching out.
Pros:
Tangrowth, although it possesses excellent Defense and good attacking stats, is usually outclassed as a wall due to lack of reliable healing and horrible Special defense. While the latter can't be fixed, Regeneration helps tremendously with the first; Tangrowth can sponge an attack and switch out, healing 30% from Regeneration. This allows Tangrowth to become a much more effective wall.
Cons:]
Although Leaf Guard helps, as a tank it's not really very useful except for blocking Toxic. Chlorophyll only helps with attacking sets, and defensive sets like Regeneration much more.
Lucario
http://smogon.com/dp/pokemon/lucario
Dream World Ability: Justice Heart
Ability Characteristics:
This pokemon rises one stage in attack when hit by a Dark type move.
Pros:
Although Lucario liked not being flinched, an extra stage of attack lets it hit even harder than it already does. SD Lucario would become even more potent than it already was, OHKOing Hippowdon with Close Combat and doing around 70% to Gliscor with Extremespeed, KOing it after some residual damage. It could also utilize its new move Cheer Up and the attack boost and become an excellent mixed sweeper.
Cons:
Not being able to be flinched allowed it run through Choice Scarf Jirachi with Close Combat, but had little utility outside of that.
Typhlosion
http://smogon.com/dp/pokemon/typhlosion
Dream World Ability: Flash Fire
Ability Characteristics:
Grants immunity to Fire-type moves and increases the power of Fire-type moves by 50% when hit by a Fire-type move.
Pros:
Choice Scarf Typhlosion just became a lot scarier. With access to Eruption and Flash Fire, Typhlosion can launch double STAB Eruptions and outrun almost all non-boosted pokemon if it comes in on a Fire attack. Alternatively, one could use Choice Specs to utterly annihilate anything in its path, but then its speed is pretty mediocre.
Cons:
Blaze allows Typhlosion to repeatedly use double STAB boosted Fire attacks, but only when it gets low on health, so it can't use a boosted Eruption like Flash Fire can.
Dragonite
http://smogon.com/dp/pokemon/dragonite
Dream World Ability: Multi-Scale
Ability Characteristics:
When this pokemon is at full HP, damage is lessened.
Pros:
Dragonite can now take the role of a defensive dragon much more easily; it can switch into many more attacks without much fear. Along with Roost, Dragonite can turn into an excellent tank that can take a lot of hits. However, offensive sets benefit too. Multi-Scale basically gives it a free turn to setup a DD and sweep.
Cons:
Inner Focus helps a lot with a lead set, allowing it to defeat Jirachi leads and take less damage from Infernape leads, but Multi-Scale can help with other leads that have powerful attacks.
Ditto
http://smogon.com/dp/pokemon/ditto
Dream World Ability: Eccentric
Ability Characteristics:
When Ditto switches in, it automatically changes into the opponent's pokemon, with Ditto's HP.
Pros:
Equipped with a Choice Scarf, Ditto now makes an absolutely top-tier revenge killer. As it switches in, it copies the opponent's stats and stat changes. Since Ditto will have the same stats as the pokemon, and have a Choice Scarf, it will outspeed and KO the boosted sweeper with their own elevated stats. Ditto's new ability provides a great new way to revenge such dangerous sweepers as Overconfidence Gyarados and Speed Boost Blaziken.
Cons:
Ditto loses Limber, but that wasn't helping it much anyway. Eccentric simply allows it to use Transform (its only move) more quickly.
Nidoking
http://smogon.com/dp/pokemon/nidoking
Dream World Abiltiy: Encourage
Ability Characteristics:
Encourage increases the attack power of moves with secondary effects by 50% but prevents said effects from occurring.
Pros:
Nidoking has never quite been OU material. He has lackluster 92 attack and 85 special attack. Despite his large move pool, he just doesn't have the oomph needed to play with the big boys. Now that Encourage adds some power to his attacks, the king just might have what it takes.
Almost every move that Nidoking would use for his standard sets is powered by Encourage, giving them a STAB boost. All the important moves that receive a boost are as follows: Earth Power, Fire Blast, Flamethrower, Focus Blast, Ice Beam, Poison Jab, Sludge Bomb, Shadow Ball, Thunder, Thunderbolt, and the three elemental punches. That's quite a resume. Notably, Sludge Bomb and Earth Power have a 202 BP and Poison Jab will have a 180 BP.
Cons:
Most likely, a simple pseudo-STAB boost won't be enough to help Nidoking. He has more problems besides low attack stats. At best Encourage will make Nidoking a premier UU wall breaker that gets bumped to BL, but even that is wishful thinking. More likely, he will solidify a place in upper UU usage as a mixed sweeper/wall breaker. It doesn't lose any good abilities: Poison point is a terrible ability and why use the luck based Rivalry when you can have a guaranteed boost from Encourage.
Espeon
http://smogon.com/dp/pokemon/espeon
Dream World Ability: Magic Mirror
Ability Characteristics:
Reflects status back at the user. Also reflects entry hazards.
Pros:
There's no doubt that this is an amazing ability. With Magic Mirror, Espeon might finally have that edge over Alakazam it's been waiting for. With its excellent special attack and ability to reflect both status and Entry Hazards, it makes a great switch-in to almost any wall. It can also run a viable lead set, not letting the opponent setup hazards, although its lack of priority is disappointing. Espeon has an advantage over Alakazam in that it doesn't have to worry about paralysis, which cripples Alakazam.
Cons:
Although Synchronize was nice, the pokemon trying to paralyze Espy aren't usually fast, and so paralysis doesn't really help, and it ruins plans of poisoning the bulky walls that tend to use Thunder Wave. Magic Mirror reflects the status back, baking it infinitely better than Synchronize.
Lugia
http://smogon.com/dp/pokemon/lugia
Dream World Ability: Multi-Scale
Ability Characteristics:
Reduces damage taken when pokemon is at full health.
Pros:
While Lugia is already an excellent wall, Multi-Scale allows it to take even less damage from attackers that might try to scratch its mighty bulk. If Stealth Rock is off the field, Lugia can take a +2 Stone Edge from the standard RP Groudon and setup a Reflect, letting it halt Groudon's sweep. It also takes a paltry 31.7% - 37.5% from a nonboosted Stone Edge if it's at full health, letting it fully halt Groudon's rampage with Reflect and Roost off any damage taken.
Cons:
Lugia now loses the ability to Pressure stall its opponents. However, considering Lugia's use as a wall against physical sweepers, this ability isn't very useful. Also, Stealth Rock needs to be off of the field to have Multi-Scale activate, so a spinner is absolutely necessary to utilize this ability.
Thanks for reading, and don't be afraid to tell me how wrong I am. I appreciate any help you guys could give me.
