Hearthpwn

I like this in Control decks too. On turn 3 its a Lifesteal minion, on turn 15 it will destroy a minion and heal 6

Ooh, this looks like Duels starter deck gold to me! In the first couple games of your run (which is your starter deck's primary responsibility), your deck will be so small in the first place that activating this guy will be a cinch.

I get that they are trying to go for a discard like warlock archetype for this expansion, but unless there's an actual reason to purposefully destroying you deck. this card could be used in an aggro deck since aggro warlock draws so many cards.
