Palafin

Ability

Zero to Hero
Once during your turn, when this Pokémon moves from the Active Spot to the Bench, you may search your deck for a Palafin ex and switch it with this Pokémon. Any attached cards, damage counters, Special Conditions, turns in play, and any other effects remain on the new Pokémon. If you switched a Pokémon in this way, put this card into your deck. Then, shuffle your deck.

Its physical capabilities are no different than a Finizen's, but when its allies are in danger, it transforms and powers itself up.
