I think his level 1 is pretty good, he great mixups with it and a few semi practical hcs, although overall is inferior to the easy hc into lvl 1 specials. His 2 is trash and his 3 is meh, it becomes downright awful if they know how to glitch out of it.
I'd say his move set is over lacking. It would be nice if he could do more with his square moves. They are very punishable and only reward him with like 60-70 ap at best if he does hit.
