>>19626779In singles, pair him up with Cofagrigus with Mean Look and a single physical attack, the rest is up to you.
First send in Cofagrigus, use Mean Look and attack once, opponents ability would turn to Mummy.
Switch to Slaking, use Pursuit, Slaking now got Mummy.
Kinda stupid, but it works, since carrying a physical attack on Cofagrigus is redundant.
Or you could try baiting a physical attacker with Cofagrigus and prepare a Blissey or AV mon to combat special attackers.
