Hearthpwn

If overflow is active for you... nah, that's another game.

Good with Kael'thas Sunstrider and Gadgetzan Auctioneer, or some other card with 0 mana synergy. Might be good in a mill deck where you want to avoid overdraw. Other than that, pretty meh buff.

While this kind of buff might seem a bit meh when you're at turn 7+, it's a 0 mana spell - which always have potential. Especially in a metagame that includes Kael'thas, and could always see Gadgetzan Auctioneer doing something if there's a reason to turbo-draw.
