Hearthpwn

This is an aggro deck that tries to keep flooding the board with minions using Meeting Stone, Sigil of Summoning, Vile Call, and Fel Guardians, and then use a combination of Trueaim Crescent, Animated Broomstick, and Ace Hunter Kreen to get the most out of them. It's not unusual for the deck to fill a board in a single turn, with Kreen and Broom to help clear the opponent's board at the same time. Kazakus, Golem Shaper can also be used to produce a golem that buffs your minions, for large swing turns.

The remaining cards are mainly either additional aggro minions (Intrepid Initiate, Demon Companion, etc), card draw (Acrobatics, Skull of Gul'dan, etc), or utility/tech (Illidari Studies, Acidic Swamp Ooze, Infectious Sporeling, etc).

Finally, like most Demon Hunter decks right now, this also includes Illidari Inquisitor as a finisher, because it's just unequaled in that role.
