This is the Trump Discard Warlock w Malchezaar’s Imp. It’s a simple build with 2 of’s for all the card choices and plays off loads of discard synergy mechanics. If you can hit the discard on the right cards you can run away with a game.
It plays out much like a Zoolock deck. You’re looking to flood the board, with the main difference being the extra card draw and synergy with the discard battlecries. I can see this deck being stronger than Zoolock, the list might need further refining as the Malchezaar’s Imp card is really new, but it’s looking to be really strong.
