How to use: First, open the box and take out the 60 - card ready - to - play deck. Familiarize yourself with the reference cards and the rules booklet. Set up your single - player playmat, place your damage counters nearby, and use the large metallic coin for coin - flip decisions. You can either play offline with friends or use the code card to play online. For the booster sets, you can open them to get new cards and expand your collection. Notice: Keep the cards away from moisture and direct sunlight to prevent damage. Don't bend or crease the cards. When using the playmat, clean it gently with a soft cloth if it gets dirty. Maintenance: Store the cards in the deck box to keep them organized and protected. You can also use card sleeves for extra protection. If the metallic coin gets dirty, you can clean it with a dry cloth.
