So infinite damage is possible if you can dodge the board wipes and silence. Set up a board with:
Kelthuzad, 3 sludge beltcher, tournament medic, and animated armor.
Stormwind won't attack once you have kelthuzad and 3 sludge belther for some reason so you are immune to his minions. You take 1 from fatigue each turn thanks to animated armor, but gain 2 from tournament medic so you are immune to fatigue. Ping Stormwind for 1 each turn!

After around 35 or so games, noticed the deck wins mostly by luck, and even those victories come rarely. Dies easily to aggro (which is a big part of the meta currently) and only really shines against fringe decks. Brann really isn't worth losing serious card advantage with a standard zoo build
