Cannon Bug (Forretress) @ Custap Berry
Ability: Sturdy
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Stealth Rock
- Rapid Spin
- Toxic Spikes
- Explosion
I went with Forretress mostly for his utility with hazards, and his ability to take out most hyper-offensive leads. He's a hazard setter/suicide lead, with Rapid Spin thrown in to counter other hazard setting leads. I can also reserve him for a surprise Custap-Explosion later if I need to drop some damage on an annoying wall, or, as often is the case, said HO lead has priority moves.
Poseidon (Swampert-Mega) (M) @ Swampertite
Ability: Damp
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Brick Break
- Earthquake
- Ice Punch
- Waterfall
Aside from being my personal favorite mon, Mega-Swapert is one helluva Physical Sweeper, and outspeeds most of the tier after Tornadus's Rain Dance. He covers Tornadus's weaknesses as well, making him my go-to for an emergency hard switch. I opted for extra elemental coverage over Rain Dance since most Mega-Swampert I've seen have trouble against physical walls with easily exploited weaknesses, like Mandibuzz.
Clever Girl (Umbreon) (F) @ Leftovers
Ability: Synchronize
Shiny: Yes
EVs: 252 HP / 4 Def / 252 SpD
Calm Nature
- Wish
- Protect
- Taunt
- Foul Play
I went with cleric Umbreon for it's impressive bulk and ability to counter slow Physical sweepers. It can tank most super-effective attacks at full health, and be back to full after Wish/Protect shenanigans + Leftovers. Taunt is a necessity to counter walls like Mandibuzz and Florges, and Foul Play is just so dickishly fun once any Fairy threats are cleaned up.
Chubs (Blissey) @ Leftovers
Ability: Natural Cure
EVs: 252 HP / 252 Def / 4 SpD
Bold Nature
IVs: 30 Def / 30 SpA / 30 SpD
- Wish
- Protect
- Toxic
- Heal Bell
Blissey is the full-time cleric for the team, more for cleaning off burns from Mega-Swampert and the frequent Toxic and returning fire with it's own. Of course, it also rolls Wish/Protect + leftovers shenanigans to promote the slow painful kills late game. Provided, of course, said last-mon-standing isn't immune or rolls Taunt.
Whoosh (Tornadus) @ Damp Rock
Ability: Prankster
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Rain Dance
- Taunt
- U-turn
- Hurricane
Tornadus is my utility mon, setting up for Mega-Swampert's sweep with Rain Dance, or Taunting clerics and walls. U-turn, combined with his ungodly unboosted, speed let him swap out of most annoying Electric scarf-sweepers before they get going. Finally, Hurricane combined with 8 turns of downpour can make him a surprisingly powerful Special Sweeper and good counter for most of Mega-Swampert's checks.
Jello (Reuniclus) @ Life Orb
Ability: Magic Guard
EVs: 252 HP / 4 Def / 252 SpA
Quiet Nature
- Trick Room
- Psyshock
- Focus Blast
- Shadow Ball
Reuniclus is the counter-sweeper of the squad, liberally using Trick Room to nullify Scarf-sweepers that can OHKO most everyone else on the team. His extra bulk allows him to safely get 2HKOs on fellow Psychics and even the occasional Dark type.
I like how it runs, but I've found some major sore spots with it, namely Fairy types and low-maintenance walls. I'm considering trading Jelly for an Empoleon seeing as how a PSY/GHO/FIG spread isn't really necessary for most fights. Not to mention Jelly winds up 2HKOing most of the time, even after Trick Room.
