Hearthpwn

This card might be extremely useful

I wonder this could somehow fit into Cubelock... of course one does not want to get this one pulled, but Cubelock tends to always have some sticky demons on the board, giving one of them +3 attack and lifesteal could be a fat health boost necessary against those aggressive decks that can overcome fat demons. Even against Reno Priest this could bring enough health such that they can't safely execute the Spawn of Shadows combo

IMO too bad with Voidcaller and Skull of the Man'ari. U can play it in early turns but  u havent small minions to use battlecry.

yes, I also think it won't be good. also you don't want this from Guldan

Now I wonder who voted me down, I mean, I just said "I wonder", didn't even claim that this is good

Will be great in my Wild Demonlock.

minions with removal attached to them are king in hearthstone. If warlock is reliably able to stick demons then this is a 3/4 deal 3 damage, which are pretty good. Health restoration in warlock has been notoriously game breaking aswell but early hero powers do not synergise with this card
