Cosmic Eclipse · 187/236
Chaotic Swell is a Trainer card from the Cosmic Eclipse expansion of the Pokémon Trading Card Game (card 187/236, Uncommon).
Whenever either player plays a Stadium card from their hand, discard that Stadium card after discarding this one. (The new Stadium card has no effect.)
This card stays in play when you play it. Discard this card if another Stadium card comes into play. If another card with the same name is in play, you can't play this card.
