This is one of the few Tavern Brawls that i played more than one game. Finally a format where Gnomeferatu is good
I also enjoyed playing Rogue, it has the best tech cards. Beneath the Grounds against Reno/Kazakus decks, Gang Up against Warlock disruption (it's great when they mill you with Gnomeferatu you Gang Up it and they concede :D) and obviously a must have in every deck - Loatheb (+ Shadowstep) autowin card against every mage.
Also there is currently a bug where if you have only 3 cards in your deck you lose the game.
