I used this deck and the treasures All Together Now and Rally the Troops to get my first 12-0 with Warlock. Generally speaking, adding more soul-generating cards is the best for this deck and more batteries in general. I retired any run at 3 games if I was not offered Rally the Troops for that is what makes this deck really good past game 3. Good luck if you wish to try!

Also note, you can probably replace Chittering Tunneler with Venomous Scorpid, but I liked the extra attack when played early, though poisonous can be much superior in many situations.
