hmm, on the surface i'd say vision should take this, but his ai is sufficiently advanced that Charles might be able to interact with it. his mind blasts have also ko'd a sentinel in the past (and I think he was in a weakened state at the time??) so there's a chance he could take vision out anyway.
if vision goes intangible, i'm really not sure at all how the mind blast would affect him since it seems more like a force/physical attack. tough match to call imo.
