Pokémon TCG Pocket's first expansion is due to be released later tonight and brings with it dozens of new cards to collect and battle with.

Pokémon TCG Pocket seems to be going rather well for The Pokémon Company. With rumors that the game has netted over $200 million in its first month, it’s now been officially announced that the mobile app has been downloaded over 60 million times since its October 30 launch.

A handful of cards break this one per turn rule, however, by allowing for additional mana generation. Of the four best decks in Pokémon TCG Pocket — Mewtwo ex, Pikachu ex, Charizard ex, and Starmie ex — only one (Pikachu) doesn't rely on these additional mana generation cards. They're therefore very powerful.
