Pokémon TCG: Build & Battle Boxes let you have a match anytime you want with cards from the new Sword & Shield—Rebel Clash expansion. Each Build & Battle Box contains a 23-card Evolution pack, which includes an exclusive foil promo card and is designed to give you a solid foundation for building a new deck. Each box also includes four 10-card booster packs from the Sword & Shield—Rebel Clash expansion.
These boxes are designed to build a 40 card deck. Try to include Pokémon of types that have a lot of cards in your pool, and finish up using your Trainer and Energy cards.
