Devolution Spray is a Trainer card from the 1999 Pokémon Game (Base Set) expansion of the Pokémon TCG. The card’s artwork by Keiji Kinebuchi shows a bright yellow, donut-shaped spray canister emitting a mist against a smoky red-and-black background. In gameplay this Trainer item lets a player devolve one of their evolved Pokémon by discarding its Evolution cards, which also removes any status conditions. As a rare (★) card from the Base Set, its classic illustration and unique effect make it a nostalgic collectible for fans of vintage Pokémon trading cards.
