Zoolock. You need to only substitute Dark Peddler and Imp Gang Boss. Imp Gang Boss can be changed for Harvest Golem. Dark Peddler is harder to substitute but you can try Acidic Swamp Ooze, Crazed Alchemist and Demonfire. If you can, try to buy at least first wing of LoE for Dark Peddler because its value is incredible.
This season I hit legend with list below.
