Just wondering, but does dreadsteed basically make for an instant win when playing against the crone? If you put a dreadsteed to right of Dorothee won't you have an infinite number of taunt creatures to defend your minions?
I'm surprised noone has mentioned Moat Lurker. Turn 2 <anything big> + Moat Lurker (I used Ysera) and you basically win the game. The minion comes back at full stats.
