What deck did you use? I'm stuck in Rank 12-15 hell.
An Even Paladin deck. It takes a good amount of play to really get the hang of it, but once I got my mulligans down and overall play, I was crushing people. It took me about a week to get truly comfortable with it and not misplay as much as I was at the beginning. Lots of comeback capabilities as well.
