Kurt's already dated a sorceress who called herself 'Magik.' That's not an association either character needs right now.
It would be hot.
But I think Magik can do much better.
Magik & Legion's relationship always seemed very complex to me, rather like God Doom & Molecule Man: very powerful & lonely individuals bound together by power politics. (The bit in Legacy with Legion, Magik & the SoulSword seemed complicated; her line "I've wasted my Life!" seemed like over acting, Magik delivering a line that had been practiced ahead of time.)
I've been for Logik ie Loki/Magik for a long time, but ever since she got Dormammu begging on his knees before her, some sort of thing might be going on there; Hell Lords & her formative years with Belasco might make her vulnerable to Very, Very Bad Boys. (Mephisto, Amara & Magik might be an interesting triangle like Betty & Veronica!-)
