Your attack does not wholly supercede mine. It overpowers it, but it is also losing energy in the process. It is also still being split, and would therefore be off-target. The diamond is also insulated against energy. Says so right on the sheet. It still has to punch through graphene armor. 

I highly doubt this attack would spell doom for Corban. Conveniently overlooking every factor that doesn't work in your favor. I've seen this before, somewhere....
