First, there's no need for over-inflated scans that mess up the page good friend.
But that aside. Beast is talking about de-powering mutants specifically.
But you must've overlooked the Strange scene you just posted
where he declares at the end her:
"Magic is woven through Everything. Welded to ALL There is"
----------------------------------------------------------------
Also, aside from the original HOM showings which showcase her power (chaos wave)
crashing into Otherworld, after sweeping several realities,
it bashed down the Starlight Citadel, which contains an Omniversal Nexus.
This caused all the realitieS connected to such to blend together as one,
later tearing all of them to bits as Roma warned.
Except for Otherworld, 616 which was engulfed in Wanda's warp when she altered the Earth,
and the "Ascension." (God?)
I also believe initially realms outside omniversal space-time were untouched like the WHR,
but in Roma's warning no dimension was safe.
----------------------------------------------------------------
Anyway almost 2 years later, in Die by the Sword,
we learned what was obvious from HOM.
Her power that spilt out of 616 (chaos wave) tore the Omniverse to pieces,
and then it reverted itself and put everything back. 👆
Of course, her power wasn't sentient so it wasn't going to remodel the Omniverse itself,
NO,
this was when Wanda uttered: "no more mutants."
Which was meant to put everything back to normality, with the exception of many mutants.
So in that uttered thought, she reverted 58163 back into 616,
and she restructured the Omniverse back to what it was before her power warped it.
