Hero PowerLifestealDeal 3 damage.
Really really strong. But it balances the crappy battlecry and expensive mana cost.
Really Great Hero Power
Even better then fake "discover a spell" hero power.
Sweet Jesus. This is almost as strong as INFERNO! and DIE, INSECT!
Probably the best hero power yet... very flexible, usefull in nearly all situations
Deal 3 damage and Restore 3 health to your hero ... Well that sounds great for warlocks !
