With the new addition of the high power discard cards from Rastakhans Rumble, discard warlock is performing well compared to its earlier iterations. This deck has multiple tiny synergies in it, such as soul infusion with Jeklik, Cataclysm with Malchezars imp, etc etc. the amount of cheap discard cards the deck offers allows it to complete the quest rather quickly, utilizing cards such as howlfiend. The deck also offers good early game tools like shriek and reckless diretroll to help contend the board against aggro.
