Hero PowerDraw a card and take 2 damage.
sworg would love this
Fun Fact: In World of Warcraft, Life Tap actually restored the caster's Mana instead of drawing a card.
Drawing a card is one of the important mechanics of the game...the only hero power which it can draw card at the cost of 2 health (7% of your max health) while in WOW it costs 15% of your max health...it's really OP if you have Chromaggus
This is why Warlocks are so powerful and consistent; 2 life and 2 mana to draw a card each turn is just bonkers.
