New Extradimensional Crisis Themed Booster Pack

In Extradimensional Crisis, players can collect Ultra Beast Pokémon cards such as Buzzwole ex, Blacephalon, Nihilego and Guzzlord ex. First appearing in the Pokémon Sun and Pokémon Moon video games, Ultra Beast Pokémon are mysterious life-forms from another world that emerged from Ultra Wormholes and give off a mysterious, alien energy.

In celebration of their debut in Pokémon TCG Pocket, a new Ultra Beast-themed binder cover will be available for players to obtain through the Shop with shop tickets beginning May 29. Players will also be able to showcase their favorite card in a new floral display board, obtainable using event shop tickets gained through the upcoming wonder pick event between June 11 at 11 p.m. PDT to June 28 at 10:59 p.m. PDT.

Pokemon Trading Card Game Pocket is now available for smartphones on both iOS (via the App Store) and Android (via the Google Play Store).
