I had the same idea as you to play a warlock deck that isn’t zoo, thus I theorycrafted this deck but the games I played isn’t smooth against Agro decks. It’s can handle silentpriest but this deck definitely needs more refining. Your constructive comments is appreciated.

i play some warlock here and there, can anyone help me try out this deck? http://www.hearthstonetopdecks.com/decks/controlock-cheating-death/
