...What? She came back when Remender was still writing. She was in the vol 2 UA. And after that Secret Wars happened.
That random mention of Wiccan and Speed? LOL. I'm not sure why you're so pressed. Well I guess I know, it's because I said I wanted her to go back to being a mutant pages ago. Which doesn't have anything to do with the fact that MCU synergy hasn't helped her like we wish we had.
Wanda is an unlucky character. The things that usually help other characters always end up not affecting her positively for some reason. Unless a new editor or a main Avengers writer cares about her, we'll probably just keep getting crumbs...
