So that's why Magneto is alive in Excalibur and claimed the other Xorn was an "impostor"?
Way to go Marvel, you just took a huge dump on Morrison's arc. It was already bad enough that they completely ignored Wolverine finally finding out his history( check out The End--he doesn't know jack). I hate how they pick and choose which parts of Morrison's run they want to include in current continuity.
I mean, I knew that they were going to revive Magneto sooner or later--but with a half arsed explanation like that? That completely took the steam out of the entire Planet X arc. It concluded with great deaths for a great villain and heroine (albeit for the umpteenth time), now it's just an average arc.
