Check out my profile where I'll try to list some of the best wild decks for each archetype. I always appreciate suggestions to improve my decks.

Majordomo priest: Complete your quest then pull Majordomo Executus out of your hand with Coffin Crasher and kill him with Shadow Word: Death. Then play Amara, Warden of Hope to have one of the strongest hero powers in the game combo'd with 40 health.
