How to use: First, open the Build & Battle Stadium box. Take out the two Build & Battle Boxes. You and your friend can each pick a box with a ready - to - play 40 - card deck. If you want, you can open the booster packs and add the new cards to your deck. Then, set up the Basic Energy cards, damage - counter dice, coin - flip die, and coin condition markers. Now you're ready to start the battle. Note: Keep the cards away from water and direct sunlight to prevent damage. When using the dice and markers, handle them gently to avoid breakage. Maintenance: After each play, put all the cards back in the collector's box. You can use a soft, dry cloth to clean the dice and markers if they get dirty. This will help keep your Build & Battle Stadium set in good condition for many battles to come.
