The Pokémon TCG Sun & Moon–Cosmic Eclipse Elite Trainer Box (2020) is a sealed collectible set from the final expansion of the Sun & Moon series. The box itself features cosmic-themed artwork with holographic stars and stylized silhouettes of Legendary Pokémon like Arceus, Dialga, and Palkia glowing in green, pink, and blue. Inside are eight booster packs from the Cosmic Eclipse set, along with themed card sleeves (featuring the Arceus & Dialga & Palkia artwork), Energy cards, dice, and play markers – everything needed for deckbuilding and play. This set is notable for introducing powerful TAG TEAM Pokémon-GX (including the first-ever three-Pokémon team Arceus & Dialga & Palkia-GX) and Tag Team Supporter cards, making the Elite Trainer Box a standout Pokémon trading card item for collectors and competitive players alike.
