In your hand you want to get C'Thun's Buff to activate the Twin Emperor Veklor. If you're facing Aggro Decks try to Mulligan for Demonwrath and the Twilight Geomancer.
I tried a new Renolock in standard with C’Thun and I got a 10-1 win streak.
The strength of this deck is to play every Board Clear available in Warlock from Demonwrath to DOOM!
In this deck DOOM is incredible because even if it’s a late card you have many options to survive before. And when you get it it allows you to draw to get Reno Jackson, C’Thun or Jarraxus.
The rest of the deck is Taunt minions, Heal and C’Thun’s Buff.
C’Thun in this deck is rather considered as a defensive tool, that’s why there are so few buffs. If you can’t get him to 10 early enough you may consider replacing Earthen Ring Farseer with Twilight Elder. However in the late game if C’Thun got killed you can play it one more time with Doomcaller.
Concerning Doom, a lot of players thought it is a dangerous card when you’re playing Warlock because of your hero power. But this deck actually plays more on curve and you’re going to try dealing with the opponent’s threat early.
So you won’t find yourself with that many cards in hand. That’s also why the deck doesn’t include Twilight Drake or any Giant.
