Time for gimmicks:

Weavile @ Leftovers
Jolly nature
252 Atk, 252 Speed, 4 HP
-Ice Punch

Swagger + Punishment is a gimmicky combination with Substitute, best used with entry hazard support as this set encourages switching. Substitute grants a shield behind which you hide, set it up on the first switch that expects revenge killing Weavile, and proceed with Swagger as they break your sub. Then continue to set up subs until they hit themselves in confusion, then raise their attack further with Swagger, and then brutally hit them with STAB Punishment. Ice Punch is additional STAB coverage.
