Kabufuda

Kabufuda were Rokugani decks made up with 40 small stiff cards which used numeric suits. Card games in Rokugan, most of which were adopted from gaijin games introduced during the period prior to the Battle of White Stag. After that confrontation, foreign playing cards were banned but new types of card decks were created.
