Gonna go lazy FLCL style.
Delibird @ Focus Band
Trait: Hustle
EVs: 252 Atk / 252 Spd / 4 Def
Jolly Nature
- Ice Shard
- Aerial Ace
- Ice Punch
- Rapid Spin
The master of coming in and dying. Delibird has the important, but not very honorable role of being death fodder. Didn't really matter who I put here but Delibird has a chance of being useful if he were to survive due to Focus Band, Stone Miss or whatever. He can outspeed both opposing pokes to either hit them hard (I dunno if it kills or not) or Rapid Spin the hazards away for:
Sneasel @ Choice Band
Trait: Inner Focus
EVs: 252 Spd / 4 Def / 252 Atk
Adamant Nature
- Ice Punch
- Ice Shard
- Low Kick
- Pursuit
After Deli goes down it is green for Sneasel to come in. And what's Champion Sneasel's job? To OHKO both of the opposing pokes before they even can move with ICE SHARD.
252 Atk Choice Band Sneasel (+Atk) Ice Shard vs 4 HP/0 Def Torterra: 101,2% - 119,28% (Guaranteed OHKO)
252 Atk Choice Band Sneasel (+Atk) Ice Shard vs 0 HP/4 Def Altaria: 129,9% - 154,64% (Guaranteed OHKO)
So yeah that's pretty much it. Sack n' sweep. If Torterra were to get a Rock Polish up it wouldn't matter due to the priority with Ice Shard.
