For those who love a deck with high risk/reward you should try this C'thun Miracle Warlock

Using stealer of souls to pull tons of cards and quickly get to your C'thun pieces can be crazy exciting although not for the faint of heart (but at least you can take heart in the fact that even if you take lethal damage from Stealer of Souls, at least you beat your opponent to it)

I've made a video deck guide discussing aspects such as the mulligans, combos, strategies and win conditions as well as my overall verdict for the deck

Enjoy
