Hearthpwn

This deck isn't the first anti-aggro Control Warrior I've built. I think the first one I made was in TGT, when I tried cutting all the late game legendaries from my deck and ran some more taunts and removal instead.

However, this is the first time I think the deck actually works (at least somewhat). With the recently added Dead Man's Hands the opponent can be brought into fatigue, which is made easier with Coldlight Oracles. What makes the deck different from other Mill or Fatigue Warriors, however, and makes the deck optimized against aggro, is the inclusion of Alley Armorsmiths, as well as the new Drywhisker Armorers.

The gameplan is dramatically different against control and aggro decks, unfortunately, so sometimes you have to just guess which one the opponent is playing. Generally speaking, against aggro you want primarily Armorsmiths and Drywhisker Armorers in your hand, and after those your AoEs, while against slower decks you need two Dead Man's Hands and a Coldlight Oracle as fast as possible.

Other than that, your strategies against specific decks are more of generic knowledge on the opponent's deck than on your own, but if you have a question on some matchup feel free to ask and I'll do my best to try and help :)
