This sealed 3-pack blister is an official Pokémon TCG product from the Sun & Moon: **Crimson Invasion** expansion (2017). It contains three Crimson Invasion booster packs (10 cards each) along with a promotional Decidueye trading card. Crimson Invasion focuses on Alolan Pokémon and Ultra Beasts, and the included Decidueye promo is printed as a “Cosmos Holofoil” Black Star Promo with vivid artwork by Kouki Saitou. The card’s galaxy-style foil pattern and dynamic Decidueye illustration make it a standout piece, appealing to collectors and fans of Alola’s starter evolution. Players will enjoy cracking open the packs for new cards, while collectors will value the sealed condition, nostalgic set theme, and exclusive holofoil Decidueye in this product.
