The Witch has plenty of power...but Magik has real ability.

What is Magik's power set?

Magik can teleport through time and space. She has her own dimension Libmo she is absolute ruler of. She has her soul sword which can dispell any magics and she can perform loads of magic herself having studied under Belesco for years and years.

I don't really think what Wanda does is really Magic, so I don't think the sword would work. However, if she can teleport through time and space, Magik would more than likely take this one home.
