This is the deck I played in the current brawl. As you can see, I managed to achieve 10 victories with it. Sudoku Zoolock can be a real monster and for a good reason - the Neferset Thrasher-Diseased Vulture combo is busted af. Before I continue with the guide, I would like to say the following:
against combo and control - a 1-drop, a 2-drop, Neferset Thrasher and Diseased Vulture would be the dream scenario. But if you find many cheap minions to play in the first few turns, you will be fine.
Against aggro. Being ahead on tempo is the most crucial strategy here. Hench-Clan Hogsteed and Magic Carpet are the MVPs. Annoying sticky threats can be easily dealt with, if you cast Spirit Bomb on them and follow up with a Nethersoul Buster on the same turn. Use Spellbreaker, in order to deal with the opponent's taunts, magnetized mechs and buffed minions.
Against control. Against this particular play-style it's very important to apply as much pressure as possible early on, so that the opponent doesn't manage to overcome it. At the same time, play around certain board clears (Brawl, Warpath) by not commiting too many threats on the board. In this particular MU the minions from the self-hurting package will be the MVPs, so use them wisely.
