Serperior VSTAR
Royal Tornado, which can be used as GCC, deals 190 damage and drains the energy attached to Pokémon on the field.
It's a skill that can be transferred to other Pokemon of yours as you wish!
And the VSTAR power, Starwinder, deals 60 damage x the number of energy attached to this Pokémon, and replaces it with a benched Pokémon!
The damage isn't on the low side, and I think it's a pretty powerful card in that it can transfer energy at will.
