Unless this show proves otherwise, I'm not sure if she is as reality-bendingly powerful as she can be in the comics.
Well, at the moment we are not seeing the same reach as depowering 90% of all mutants. We have... Vision alive, a weird TV environment, and pregnancy. And not all of it needs to be her.
It is also possible that this is all mindscape, given her mind-influencing power. I'm just saying don't rule out other alternatives just yet.
