Mostly what Obryn said, but a couple notes for U&Y specifically. I cleared it a while ago when I still had an un-uvo'd U&Y to use as a leader with a friend hypermax uvo, so I'm not sure what I'm going to do for leader this time around. I tried it once with B/L Isis and died on Raphael (I was sad). That was with Batman though, so I think flipping him for G/D Ceres could do the trick. Izanagi for the boss, and Ceres makes him going below 50% just like a skip turn.
