Mastermind vs. Professor Xavier
It seems that the only way to beat a telepath is through illusion or delusion. Mastermind destroyed the very first Phoenix...applause to him. He kicked prof.s ass in the movie. Could he push him down a flight of stairs in the book?
The illusionist in the movie was a "Jason 143," credited as William Stryker's son. The Jason Wyngarde Mastermind is not related.
Mastermind has fooled the X-men before, but were more often able to figure out the illusion. Mastermind was only able to manipulate Phoenix [briefly] only because his abilities were enhanced through a mind device created by White Queen to appeal through her feelings.
I think Professor Xavier could handle this minion with little problem. If Mastermind ever achieved the illusion degree shown through that comic of X-men - Heroes for Hope (I think that's what it's called) where an unknown character was raising the upmost fears of the then X-men...
Wolverine - beast vs. humanity
Shadowcat - weakness, anorexia?
Nightcrawler - religion, redemption?
Magneto - human retaliation
...
Read Age of Apocalypse and see what becomes of Mastermind. The person who destroys him is lesser than Xavier. Also, a strong mind can see thru illusions. Xavier's mind is among the strongest.

A "real" illusion can render telepathy fake. That's why they made mastermind a coward. If his illusion got to powerfull, he could beat even franklin richards and his reality power.
A strong telepath can sense the mental probe. No doubt a good illusion will convince most people (I'm unsure if an illusion can illustrate falling), but its still not enough to fool someone like Charles Xavier, especially since he can make illusions as well.
Jason Wyngardes powers worked best against very powerful minds so say the scenario was a sneak attack then I'd say Wyngarde has a chance.
However since this is a direct assault I'd give it to Xavier. I think Xavier already scared him off in X-Men - First Class (Volume 2)...can't remember which issue of the top of my head but it was a 2 issue arc.
