Three episodes from the first season of the animated series inspired by Yu Gi Oh trading cards. In 'The Heart of the Cards', Seto Kaiba forces Yugi Moto's grandfather into a duel - in which he takes his most valued card, Blue-Eyes White Dragon. Yugi and his friends step in, and a duel between Yugi and Kaiba begins. In 'The Gauntlet is Thrown', Joey decides he wants to learn how to be a duellist, and asks Yugi's grandfather to train him. 'Journey to the Duelist Kingdom' sees Yugi reluctantly taking part in the Duelist Kingdom tournament after his grandfather's soul is taken by Maximillion Pegasus.
