Collapsed Stadium崩れたスタジアム

Each player can't have more than 4 Benched Pokémon. (When this card comes into play, each player discards Benched Pokémon until they have 4 Pokémon on the Bench. The owner of this card discards first.)

This Stadium stays in play when you play it. Discard it if another Stadium comes into play. If a Stadium with the same name is in play, you can't play this card.
