Once I saw the warlock quest I got really excited.  No longer looking for Tickatus is of course a big plus.  So for this deck you're looking to burn through your deck as quickly as possible and hopefully complete the quest along the way.  Once you get into fatigue, hopefully all that damage that was directed at your face is now planted firmly into your opponent's.  You want to mulligan for things that help you find the bottom of your deck.  Look for backfire and Sphere at the beginning to find answers for whatever your opponent is doing.  

The Imps will be a great option to keep hitting yourself in the face to keep your quest moving and the board clear

Raise dead is great to keep your demons hitting your face and progressing your quest.  

I did not include Neeru because he isn't really part of the win condition of this deck

Rustrot should probably be kept at the beginning of this meta as there are a lot of new weapons players are sure to want to try out.

Hopefully you can make it to turn 8 and clear whatever your opponent as put up with a twisting nether.

Best of luck everyone.
