Eh not that great. It's not like Hydreigon where you can essentially move all of your energy off to heal. Chances are you have some basic energies attached to the same pokemon with the plasma energy, so you can't really run this as your typical klinklang/hydreigon style healing deck. The only use I see it having it to preserve your plasma energies, but you can do that with scramble switch and can also retrieve plasma energies back from the discard with shadow triad.
