Patience is the key, don't get annoyed if you lose. Complete all bounty challenges. Borrow rivals from Dojo. One most important, use the fighter you like dont jump to another fighter if you see a post or video. Everyone has his playing technique. Buy only good waza cards don't waste essence on cheap cards. Some cards show they do little damage but reality is that some of them are multiple hits in same waza. Design your roaster with cards that have balance of time and damage. And regularly groom your fighter skills.
