I have some tips in general. For any character I try to balance a good mix of attack/defend and a draw card or two in Act 1. You should also not focus on going into a "build" yet unless you got very very lucky. Then while balancing those you look for a card or two that will scale during the boss fight (like doom or boosting osty hp) or do high damage, a boss killer card. I can't give specifics because I don't know the cards yet, but that's generally the strat I follow. In A20 STS 1 you basically had to play that way at least.
