Hearthstone

[Gaspar]

With Voidcaller and some of the other new cards I'm thinking a midrange Warlock that runs Felguard and Pit Lord could work pretty well. Probably not reliable enough without Sense Demons though.

Why run that stuff when you can just stuff Haunted Creeper, Nerubian Egg, Echoing Ooze and Zombie Chow in your zoo deck? That's the problem. Any low cost cards that are hard to remove are just OP when combo'd with the warlock hero power.
