I've been playing with this Superstar build recently and it's hilarious, but an absolute nightmare to use with Mind-Body Unity enabled because of how quickly it takes its turns
>abuses Superstar's ability to spam ice ESP to heal himself, which also makes his turns come back faster
>actually breddy tanky when concealed
>fast turns = lots of performances = tons of AT manip
>Surprise has an interaction with Quick Grasp of the Situation where you get QGotS triggers from surprised enemies, cutting your turns down even further (it even takes place post-turn if you end your turn with a surprise so it goes past the 36AT limit)
Its disadvantages are that it's pretty weak offensively even with Willpower, and it gets exhausted in Mind-Body Unity very easily which is a death sentence, but it's pretty fun to screw around with
