Worthless in a game where potion of madness exists.
And bad even if it didn't.
PoM can be easily played around and just because a card has a counter doesn't make it a bad card.
Unless you think Jade Idol is a bad card now? Or that Pirates are all bad cards? Or Murlocs? Or Deathrattles? Or Stealth minions? Or secrets?
Skelemancer is the truth. Had a pally quest, took out my old control paladin, gussied it up with Skelemancers and Bonemares, and won all 5 needed games in a row.
