Magnetos helmet was specially designed to block telepathy, it’s not just the metal. Otherwise any classic metal soldiers helmet would render prof X useless.
Deadpool has been blown to bits. If he was cut in half, I believe the half with the heart will regenerate while the other withers. That also being said, if his heart is taken away, his body will just make a new heart. I'm pretty sure his body will grow of something that is more whole rather than make a new body from the heart.
At the risk of inciting the ire of the entire comics community on FS, my $0.02:
Iron Fist = No. His strength is sourced by gathering his internal chi. The amount of chi in a human is vastly inferior to the energy within an Infinity Stone and would not be sufficient to break it.
Black Panther = It depends. If Black Panther’s claws are razor sharp enough to cut at the subatomic level like Wonder Woman’s sword, then yes, he could pierce Luke Cage’s skin.
Professor X = See @guest comment above.
Daredevil = No. Daredevil’s extrasensory abilities have a limited range and are too slow to detect things like superspeed. Vision could initiate a ‘phase’ outside of this range and, as a vastly superior artificial life form versus a merely sensory-acute human, reappear immediately next to Daredevil and kill him.
Mantis = Yes-ish. The question is mind control, not physical strength. Not too familiar with Ghost Rider but unless he possesses resistance to mind reconfiguration, I’ll assume that Ego and Thanos have superior competency and Ghost Rider would crumble, by default. This might be negated if Ghost Rider used Penance Stare first in the fight and Mantis had some skeletons in her closet.
Mystique = No. See @lindsay response above.
Deadpool = One body. Unless there’s a comic out there to prove otherwise that I’m sure I’m missing, most leading indicators suggest that he’s wired to have one corporeal form.
Juggernaut = Yes. Once he gains momentum, Juggernaut is an unstoppable force, suggesting he has ‘infinite’ kinetic energy. Cap’s shield isn’t invulnerable and has been broken before. The breakage might be done more easily if the shield were on the ground and Juggernaut stepped on it while running versus in Cap’s hand where he ‘might’ deflect the blow.
Capt's shield is also a vibranium alloy... meaning it absorbs all that kinetic energy. The Juggernaut couldn't break it even if he wanted... he'd basically have to do what Thanos did and break it in half through sheer strength.
ghost rider is canon an angel/demon depending on when you are looking at. Either way mantis would first feel Immeasurable pain and torment eminating from him on a touch before she could do anything and even then there is a preexisting precedent of ghost riding being unaffected by psychic powers when he fought a child that was such a powerful psychic that he could raise the dead, live forever, and be undetectable to Dr. Xavier. Ghost rider was completely unaffected by his powers.
I recently commented in a post that said "dr. strange is the only hero to force his opponent to rage quit" about how when the hulk was turning all the other heros into a red mist Ghost rider fought him without so much as a scratch and eventually said fuck it and left on the pretense that there was more important things that needed avenging. Hulk refused to chase him because he knew for a fact he was one of the only things he couldn't smash.
