Team Rocket introduced Dark Pokémon, a type of Pokémon. Dark Pokémon cards have a brown and black artwork window, Evolution box and Pokédex box. Dark Pokémon have higher attack damage and lower HPs compared to those of normal Pokémon, likely due to the highly offensive nature of the Trainer. Some Evolution Pokémon feature Ken Sugimori's Red and Blue artwork of their previous Stage, instead of the usual Red and Green artwork. It also introduced Secret cards, a card whose collection number is greater than the listed number of cards in the expansion. In the Japanese release, Secret cards have the "Super Rare" rarity.
