[Budget] Reynad's Zoo V2 - Warlock Aggro

This is Reynad's Warlock Aggro Deck, that he named Zoo.

Reynad praises this deck as the best deck in the game, despite the fact that it can be built on a budget. I have included a link to his video where he goes into a lot of detail as to why he picks each card.

Updates:

(3/5/14): Reynad has swapped a few cards around. He dropped both of the Argent Commander and Young Priestess, in favor of two Dark Iron Dwarf and two Abusive Sergeant.

I had already felt the Young Priestess was under performing. Adding the Abusive Sergeant gives you more burst potential, which is nice. The Argent Commander drop was a little more surprising to me, but after trying the switch I definitely like the change. I feel Dark Iron Dwarf fits into the curve better due to coming before Doom Guard, thus reducing the chances of having to discard a high priority card. Dark Iron Dwarf is durable at 4/4 and adds the same burst that Abusive Sergeant gives. However I am not sure that Leeroy Jenkins and one Dark Iron Dwarf is not the better choice.
