HFX still reveals an OM, so he'd heal just off that as written.

Without a numbered limitation he would be a smarter draft with people like Professor X, HFX healers, and everyone else who reveals the X, but he might be paired more often with the one or two designs that add an additional X and I don't see a reason for that or him favoring X revealers other than the mutants.

I think limiting to numbered sounds good. A solid max of healing 6 wounds per round (unless OMs get taken away) and a max risk of damaging self for 3, but more often a 1-2 average. Seems fairly good. Really good damage soak potential, especially since he can engage so easily.
