This deck can only win you the game when you destroy the Wretched Tiller OTK combo.

Goal is to find Wretched Tiller and Flik Skyshiv as soon as possible. All other cards are just for card draw and removal (if you need any at all).

When you got the two combo pieces, play Wretched Tiller and destroy it with Flik Skyshiv, ruining  your opponents combo.

Note this only tends to work against Priests. Warlocks tend to have more damage to your face than you can eventually handle.

Edit 26-1: added some Eviscerate to kill some possible Gadgetzan Auctioneer if any pop up.
