Did not work out for me. Mabui's shield is not tanky enough and her heals are not much.
Although I like Mifune cause he is my very first rare, he seems to die easily by round 2.
Also is it me or does Arena seem inconsistent. I mean I win one round, I loose the next one. I win one round again and loose the next. So there's no point really.
I'm stuck from 2 days with almost the same points :(
