The first thing you need do before playing Card Shuffle is to pick a deck. You can choose from either one of 15 preset decks or you can choose mix and match for limitless possibilities. Some of the decks are accessible by typing in the commands -fire, -water-, darkness, -red, -blue, at the start of the map. Be sure to check out the in-game help menu by pressing F9 to find out more about picking your deck. After you have done that, let card battle be joined! Summon mythical monsters to attack your opponents and equip them with spell items to make them more powerful. The last man standing wins!
