I'm a huge fan of ms. marvel and having a cheaper version of her helps qith team-building, especially for champions.
While she lacks the heal mechanics of her previous versions, and the loss of outwitt is harsh, what she got is cool. Perplex on her off turns, and giant, 11atk and 4 dam on her aggressive turns? Yes please!
And the wild card ability lets you abuse things like miles' ultimates ta, or icemans x-men ability.

You will pretty much always be choosing her plus to all stats unless maybe she is pushed out and you want to be tiny in hindering with perplex def. Overall with 11atk/4dmg for most of her dial she is quite good.
