#187 Chaotic Swell - Cosmic Eclipse (sm12)

Chaotic Swell is a Trainer card from the Sun & Moon series, specifically the Cosmic Eclipse set, released on November 1, 2019. Designed by artist Ryo Ueda, it is classified as an Uncommon rarity card. The card functions as a unique Trainer card with specific rules governing its interaction during gameplay. When a player plays a Stadium card from their hand, both the Stadium card and Chaotic Swell are discarded after the Stadium card is played, rendering the new Stadium card ineffective. The card remains in play until another Stadium card enters the game, at which point it must be discarded. If a card with the same name is already in play, this card cannot be played. Its rules emphasize conditional discarding and interaction limitations, shaping its strategic role in gameplay scenarios. The card’s design and functionality are defined by these precise mechanics, offering a distinct gameplay dynamic within the Pokémon TCG framework.
