It is normally considered to be an extremely bad idea to concentrate one's forces at a specific location when you have a tonne of fresh enemies all around you. And this assault is too massive to be a blitzkrieg.

The 9 other Spriggan being illusions would actually be a great move. At least Alvarez Empire's plan wouldn't seem as dumb as it seems to be right now. >.>

I doubt there's any such thing as a Magic Signature, though. Just Magic Power. And a single person creating an illusion of so much power would make them too OP to handle. :/
