In
Duel Masters, two players play the role of duelists, using the "art" of "kaijudo" (a marketing term created for the North American version which supposedly describes the "art of battling with giant monsters," from the Japanese words
kaiju, strange beast or giant monster, and
do, way or art) to bring their creatures to life to do battle. Players battle each other by placing cards into their respective "mana zones," then using that mana to cast spells or summon creatures into the "battle zone." Each player has five shields that protect them from damage; once these are gone, it takes one successful attack to win the duel. When a player's deck runs out of cards, that player automatically loses the duel. Each player's deck must have a minimum of 40 cards in it. As with all trading card games, players construct their own decks out of cards from their collection. Players can purchase
booster packs to increase the number of cards they have in their collection. Boosters are available in English for the first 12 DM-series sets, and Japanese for each expansion set released. ==References==
