The set I am running is this:

Scrafty - Life Orb
EVs: 252 atk, 252 spd, 4 HP
Nature: Jolly
Ability: Shed Skin/Moxie
Moves:
Dragon Dance
Ice Punch
Crunch
Drain Punch
Shed Skin would keep status off of him, which would be really helpful, but Moxie is great for revenge killing, and is gives a super nifty attack boost. Bot are great abilities, but which one should I go with?
