Will do!

After Wanda turns the world into mutants, they don't start out under Magneto's control, so most of the Avengers and Fantastic Four are still planning to take out Magneto, and not even all of them have turned into mutants yet. As they story progresses, Mesmero uses the Mutant Amplifyer on himself, allowing him to control anyone in the world who is a mutant. So anyone who's mutant powers manifest, they are immediately under the control of Mesmero, and by extension, Magneto. Eventually it only leaves Iron Man, Spider-Man, Invisible Woman, and the Iron S.H.I.E.L.D. Agents (including Phil Coulson and Maria Hill).
