Aspertia City Gym (Reverse Holofoil)

Description

Aspertia City Gym (bw7-127, Reverse Holofoil) is a Stadium Trainer card from the Boundaries Crossed expansion. Each Colorless Pokémon in play, on both sides, gains 20 HP while this Stadium remains in play. It remains in play when played and is discarded if another Stadium comes into play, and you cannot play it if a copy with the same name is already in play.
