DelcattyエネコロロUnlimited Holofoil

Poké-PowerReactive Shift

Once during your turn (before your attack), you may move a React Energy card attached to 1 of your Pokémon to another of your Pokémon. This power can't be used if Delcatty is affected by a Special Condition.

Search your discard pile for an Energy card and attach it to Delcatty.
