This list is very similar to the one Chakki used to win Dreamhack. The goal is to control the board through the massive amounts of clears and win through efficient trades and N'Zoth, the Corruptor value. Playing Doomsayer as early as turn 2 can often put your opponent on the back foot. Use it to draw out the early turns and give yourself the chance to snowball in the late game.It's great to be able to cast a Solemn Vigil on turn 3 for only a couple mana after a big Doomsayer turn. I only suggest doing this if you have no other decent plays. It does however really help give you some more options to deal with threats. Using Equality with Wild Pyromancer or Consecration is an easy board clear. You can also pair Aldor Peacekeeper with Stampeding Kodo to get rid of high power minions. The addition of Ivory Knight and Arcanosmith from the new Karazhan Adventure really boost this decks potential. Playing Brann Bronzebeard in to Ivory Knight can be a game changer. When you are behind it can pull cards like Enter the Coliseum or Lay on Hands. Even a bad Paladin spell can be put to good use. Secrets cause your opponent to make inefficient plays and at the very least you can gain a few life in a clutch situation. The 0/5 Taunt body from Arcanosmith can help keep you alive long enough to regain board presence if you find yourself falling behind against an aggro deck. It certainly helps you stall long enough to find one of your board clears. Sylvanas Windrunner, Infested Tauren, and Tirion Fordring are the only deathrattle minions in the deck, but they are "Astounding" when they come back in the late game with a big N'Zoth, the Corruptor turn. Give the deck a shot and I guarantee that you will not be disappointed!
