My man, if you don't have Evolve and/or Master of Evolution, then there's no reason to play this deck.  The entire deck surrounds the premise that you'll bide your time controlling the board and buffing your C'thun while he's on vacation until you hit Turn 7, throw down Twin Emps, watch your opponent scramble to do something and if they can't get rid of 'em you Evolve on 8.  Then you hit them in the face with the Al'Akir and Grommash that come out of the Emps.  Evolve can be pretty ridiculous if you can get to midgame with some stability and I would say it's a 'must-have,' here.

I'm actually using Mukla, Tyrant of the Vale in place of Rag.  There are a lot of awesome 7 minion guys you can evolve from a 6 mana minion (Stormwind Champion,Malorne, Obsidian Destroyer to name a few) and that usually swings the game so much in your favor you just win.
