Wara's IAD mixups off of 214c nero summon are pretty good. After a knockdown 214c you can do iad j.b/j.c (high), iad j.c(whiff) land 2a (low), iad j.c(whiff) land throw. If the match momentum is neutral I think the best moves to hit confirm off of are all his A moves, j.b, and 2b (an excellent anti-air).
