Goody, I love it when the POTW is so NU!
Trick Room Sweeper:
Swalot @ Black Sludge
Nature: Brave (+Atk, -Spe)
EVs: 4 Atk, 252 Def, 252 Sp. Def
-Toxic / Fire Punch
A simple set that works best in doubles & triples. Have another Pokemon set up Trick Room, Curse it up with Swalot, and sweep. Toxic as an obligatory status move, while Fire Punch is useful for Steel-types. ThunderPunch and Ice Punch are solely for BoltBeam coverage. EVs & Nature to give a little extra oomph to its mediocre base 73 Attack.
