Reign of Fire: Zhar'doom

He has a curly tongue. Warlock pet! For the cost of 1, you can remove three ability cards in your graveyard from the game. It will give you 3 shadow dmg to a hero or ally and heal 3 from you. It's unlikely you'll be using this power around turn 4, but it could come in handy later in the late game. I would side deck it, or consider it for inclusion in a warlock deck.
