If for some reason you have decided to play more than 1 game in this week's tavern brawl, you will quickly start rising in the "invisible ladder" of brawl and hitting the meta ceiling. 

OTK-control locks and Super-tempo shaman are the 2 main decks when you start racking up wins. (when your queue time is 30 sec to 1 minute, you've entered the "high ranking" brawl)

Anti-OTK is going to be your main counter to the OTK decks, while just being lucky with your crab draws and board clear draws hard counters tempo-shaman.

This deck is slightly less consistent than the out-right OTK warlock decks, since you are running multiple tech cards (Gnomeferatu, Dirty Rat, Brann Bronzebeard), and the extra risky Coldlight Oracle, which compensates for your lack of draw, while baiting out potential mills for your opponent.

The win condition is the same as OTK, but just milling any of the 3 mandatory combo pieces (Summoning Portal, Mechwarper, SN1P-SN4P) is an insta-concede for your opponent.
