This is a one-turn kill deck that needs no adventures, just a bunch of rares and commons.
The goal of this deck, is to buff the Windfury Harpy, so you can kill your opponent almost instantly. To do this, we have cards like Gnomish Inventor or Azure Drake that helps us to draw cards, and to have what we need.
You need to play the Harpy, and on the next turn you cast on her Power Word: Tentacles, one (or two)Divine Spirit, and finally the Inner Fire, and there you go! Now you own a 22/22 (44/44 if you played both of the Divine Spirit) with Windfury!
