Well since Wanda's a mutant wouldn't Hope just be able to use her powers?
I don't know whether Phoenix would or could use Hope's powers.
Which raises an interesting question: where's Mimic in all this? He's in one of the other X-Books. He permanently has the powers of the original five X-Men and he can Mimic the powers of anyone else, as well. They should put him on the front lines!
"The trouble with fighting for human freedom is that one spends most of one's time defending scoundrels. For it is against scoundrels that oppressive laws are first aimed, and oppression must be stopped at the beginning if it is to be stopped at all."
