I know him and who he does, and I'm not exactly sure of the outcome either. He's a very high power energy manipulator that can deliver extremely powerful blasts, and works under more spectrums than Magneto. If Magneto doesn't completely 100% shield himself from one of Coldcast's 'biological EMPs,' then that's the ballgame.
On the flip side, Magneto has more experience and magnetism lets him do stuff that energy expulsion doesn't. And his defense is quite excellent- Coldcast can do an energy shield, but Mag's is better.
