she affected everything when she broke down and remade the omniverse, but it seems the no more mutants spell didn't affect all realities equally as even astonishing x-men showed alternateverses with mutants going about their business normally. I'm not sute the AoA suffered decimation either. cant really recall it being mentioned during the uncanny x-men crossovers. lots of realities visited by the x-treme x-men have no shortage of mutants either, plus there's the fact a lot of alternate futures had booming mutant populations in them.
Wanda crashed the entire Omniverse in on itself,
only 616 (Wanda's playground) was spared.
That was her power spilling out of 616 which had become 58163.
When Wanda re-arranged 616 into 58163 she made a tear in it,
and her power flowed out re-arranging likewise but without control hence, the Chaos Wave.
Now,
aside from several cool feats to and fro,
at the end, as in, "No More Mutants"
she consciously: turned 58163 back into 616,
fixed the Omniverse which means she unfolded the mesh it was,
(it was "torn to pieces"😉
and extracted the mutant gene from 90% of the race across nearly all Timelines.
(literally only several were spared) - I'll get the details.
She also affected the entire mystical plane as witnessed by Strange & Beast.
Wanda did all that in one swoop with basically a thought.
