The weapons list seems about right. I couldn't come up with any other weapons off the top of my head.

Disagree that M'Kraan Crystal should be so low on the list, though. The thing can destroy all of reality.

Maybe I haven't read enough of all of Magik's growing number of appearances in comics, but Magik's Soulsword has been damaging non magical beings and objects for a while now.
I prefer for the Soulsword to only damsge magical beings and objects. Just makes the sword more interesting, in my opinion. And, Illyana has enough other powers that she doesn't really need for the sword to be able to destroy everything.
