Two matters on this though. One, that usage is much less than she should be getting after Marvel's treatment of her since end of Secret Wars (2015). Two, Secret Wars has primed me to trust when I have a feeling that usage by Marvel is setting up for kicking a character out of the books for a time. I set the feeling aside in 2015, deciding to trust that maybe Marvel was finally ready to do things for her, and what came out of it was 2 years of her in limbo followed by her return getting hijacked to build up Havok.
I have more I can say but I'm saving it for now. Partly cause I don't feel like it tonight. Partly cause new Twilight Zone ep shortly. Partly cause it would be better said later.
I can also be reached on BlueSky and Tumblr. Avatar by kahlart.

Some people just can't accept the deaths of Rahne and Chamber etc so they want to deny it ever happened.
You're right, Cap America/Mystique wouldn't be there if all these were illusions. But why does Mystique want to do with all the prisoners (e.g. MLF) caught by the X-Men and sent to the fake Cap America?
Emma has faked Cyclops death before in such a conceivable manner that it fooled everybody so it isn't improbable that she may be doing something of the same sort here.
I feel like this and Age Of X Man are an elaborate ruse to make Marvel Unlimited users buy HoX and PoX instead of waiting.
