A Pokémon Booster Box contains 36 packs of Battle Styles Booster packs and comes factory sealed. The cards in each pack are completely random Here a description from our friends over at PokéBeach for the new Battle Styles Set: Single Strike cards deliver strong, hard-hitting attacks, while Rapid Strike cards are about sneaky, technical strikes. But its not just Pokemon that can have a Battle Style there will be Trainer and Energy cards with them too! Thats because all cards of the same Battle Style will be able to work together. The goal of the new mechanic is to encourage players to build decks that focus on one Battle Style.
