As of patch 2.51, 80 varieties of Triple Triad cards are available. While some cards can be purchased with MGP at the Manderville Gold Saucer, others can be obtained as rewards from defeating NPCs, Triple Triad Tournaments, and the completion of certain duties. As cards cannot be traded or purchased from the market, players are encouraged to challenge NPCs and journey throughout Eorzea in search of rare and powerful cards.
All cards can be classified by rarity (one to five stars). Initially, each deck can only contain one card with a rarity rating higher than one star. As you acquire more cards, however, the restriction becomes less prohibitive, and will eventually only apply to the highest tiers of rarity.
