Magneton

Poke-POWER: Reactive Recharge

If Magneton would be Knocked Out by damage from an opponent's attack, you may move any number of React Energy cards from Magneton to your Pokémon in any way you like.

If Magneton has any React Energy cards attached to it, this attack does 30 damage plus 10 more damage for each Magnemite and Magneton (both yours and your opponent's) in play.
