I like the auto-pwn power, but the first attack is useless, and the second attack's cost is too OMG-ish.
Anyway it helps because 80 can 2HKO any stage 2 ex (i.e. without resist to M/R) without any negative side effects, but the M energy requirement is the catch. I personally prefer D type stage 2's because you get to do more damage with D energy, but the +10 defense boost on the M energy is quite useless against heavy hitters... (IMO they are only good on basics to stall early on.)
Also, it should have a resistance to G or W, like the other dragons normally have...
7/10 - auto-pwn powers are always good, but it only affects d-types and is only usable when active...
