Card-Jitsu cards could be unlocked with codes from real life cards, and Power Cards could also be bought three at a time (one of each element) for 1500 coins in the Martial Artworks catalog, as of the Dojo's renovation in May 2013. Only members could buy cards from Martial Artworks, and if a player's membership expired, the cards bought from Martial Artworks would not be able to be used until membership was renewed.
