On April 4th, 1998, to coincide with the release of Episode 1 of Toei Animation's anime series, Bandai released the 1st Generation of their card game, which included 42 cards. On the same day, they also released 3 limited print promotional cards, which were Mirror Force, Swords of Revealing Light and Gate Guardian. On July 4th, 1998, Bandai released the 2nd Generation of their card game, which included 46 cards. On October 10th, 1998, to coincide with the final episode of Toei Animation's anime series, Bandai released the 3rd Generation of their card game, which included 30 cards.
