Azi

The xenan deck That got me into masters. It was surprisingly versatile in win conditions from somewhat early wins without Azindel where the urchin direct damage did alot of work to the obvious Azindel win late game.

If you manage to get Azindel down with an urchin and/or an instigator the amount of card draw from the other players deck will pretty easily run you to victory. I don't have more copies of Tasbu so I tried out Champion of mystery for the unblockable/card draw synergy with Azi, even just getting a 7/7 body down is pretty strong if they've burned through alot of removal on your 2-4 drops.
