Booster Battle Packs are designed as an introduction to the limited format of Magic: The Gathering, and are quick and fun for Magic players of any level. To play Booster Battle Packs, each player selects a deck, opens a booster, chooses up to five cards from it, and shuffles them into their deck - then the spell-slinging begins! Each pack contains two 20-card, semi-randomized decks with appropriate land cards, two 15-card Magic 2012 Core Set booster packs, a Magic learn-to-play guide, and one rules insert.
