Hearthpwn

This deck is all about high attack stat minions taking advantage of the charge ability and also pressuring your opponent into trading with you. It's curved for you to play lots of minions and trade effectively (nearly everything will have taunt so pure face is not an option). There are several really cool cards to mention:

Stubborn Gastropod - Already has taunt and it only has one attack, what's it doing here? Try a 2 mana removal card. Charge + poison is not something Blizzard has printed for a reason, it's absurdly powerful. This little guy is the cheapest poison minion in hearthstone. It's also worth pointing out that this deck also includes Ravasaur Runt which at times is just an unreliable 3rd and 4th Gastropod but can also get you so many other effects like +3 attack (5/2 for 2 is absurd, more on that later).

Vicious Fledgling - This card needs an open board but can be hugely devastating. Attacking face, get windfury, attack again, get something else. This card can single-handedly win games if you get it on a clean board and get windfury. 

Void Terror - What can you do to make a cheapo 4 or 5 attack charge minion even more broken? How about attack with him and then eat him up, then use his attack power AGAIN. Two Duskboar and a Void Terror is only 7 mana and hits face on an open board for !!21!!

Ancient Shade - The negative can just not matter to this massive finisher. Even more deadly when paired with Void Terror. Leeroy has less attack, half the toughness, and costs more. Think about that for a second.

I made the following card changes: I think Possessed Villager is pretty weak in this deck but I find myself wanting a 1 mana minion more than any other choice. Perhaps Fire Fly? I also really like the way Raging Worgen accomplishes killing a 2/3 or smaller minion AND then being a 4 attack charger in the same turn. Perhaps he's better than Ogre Brute?
