>>25034885mummy's greatest niche is on the switch-in to remove the one good thing mons have going for it.
Sheer Force gatr is going to use ice punch, send in Cofagrigus and render him a non-issue for the battle. same can apply to tough claws Mega Metagross, Charizard X, prankster on those mons spamming foul play such as Klefki and Sableye, and all sorts of other blessings the Coffin can give to swing a battle in your favor.
but all in all, you just have to be good on the prediction and make sure that Cofagrigus is switchin in on a physical attack he can stomach.
