Pokémon TCG: Build & Battle Boxes let you clash with friends anytime you want with cards from the new Sword & Shield 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 expansion. Try to include Pokémon of types that have a lot of cards in your pool, and finish up using your Trainer and Energy cards.
If you're short on Energy cards, look for the Pokémon TCG: Basic Energy Box where Pokémon TCG products are sold—it contains 450 assorted basic Energy cards, which should be more than enough to energize all of your group's decks.
With a variety of Evolution packs and four booster packs, you'll get to come up with a creative new deck each time you open a Build & Battle Box. These boxes are designed to be played using the Prerelease tournament format, where each player builds a 40-card deck and sets aside four Prize cards at the start of the game. All the rest of the rules are the same. But you can use them to create standard 60-card decks, too.
Take a look at the four promo cards available in Sword & Shield Build & Battle Boxes, and get some tips to make the most of the one you receive.
