Edit: Slowed by Googling "plasma energy"!
Very interesting indeed. The damage is only so-so, but even with the Plasma Energy requirement, its a better Rayquaza & Deoxys LEGEND.
Plasma Energy is basically a Team Themed version of React Energy, and React Energy wasn't one of those "fun but a bit ineffective" concepts. I am down with that returning for another go.
Also, while I know "Plasma Energy" fits right in with Aqua Energy, Magma Energy, etc. and is an actual, real world thing, I still like seeing it because I am a Transformers fanboy and "Plasma Energy" has specific meaning to it in that context. XD
