Wild CubeLock (After Witch Wood Expansion Nerfs)

The purpose of Cubelock is very simple: to cheat out large demons, and duplicate them with cubes. 

Before the nerf, most wild Cubelocks are running 2 Voidcallers and 2 Lackeys. However, with the nerf bumping Lackey up to 6 mana, this deck substitutes lackey for the warlock legendary weapon Skull Of The Man’Ari. It also uses Sense Demons to more easily be able to have a Voidcaller on turn 4 with a good demon in hand. Sense Demons synergizes with Skull to give you more demons to summon.

Besides those changes this deck functions just like the pre-nerf Cubelock. It uses the nerfed version of Dark Pact instead of Sac Pac simply because you can not use Sac Pac on Cubes. You use Umbra to pull off crazy combos, and Godfrey for the OP clears. Defile and Hellfire are for early game board clears, and kobold is great card draw. For single target removal, you have 2 Spellstones, a Siphon Soul, and a Darkbomb.

Doomguard, Voidlord, Mal’Ganis, and Sylvanas are all great Cube targets. And if Cube combos don’t win you the game, the massive boards provided by Bloodreaver and N’Zoth should do the trick.

One of the variable cards in this deck is Thaurissan. I believe him to be useful in pulling off massive combos with Cube and Umbra. However, based on the decks you find yourself facing, you could substitute him out for something more fitting. Such as a silence, weapon removal, early taunt, more single target removal, or other tech cards to beat the current meta.
