The second and final set of Dragon Ball GT to incorporate a Starter Deck, Shadow Dragons introduced new concepts to the game; Masked, Ability, Augment, and Shift. Shadow Dragons also reintroduced Sensei cards, which had not been seen since Kid Buu Saga. Also, many cards portraying events of the past were marked as "Flashback" cards. Perhaps the largest addition that was seen in this expansion, was the Stage 6 Personality card. The only two of these, Goku and Omega Shenron, were released in this set. Fusion also returned, with Super Saiyan 4 Gogeta.
The Shadow Dragon Saga was released in Booster Packs, as well as Starter Decks. Personality cards in this set included Goku, Chi-Chi, Gohan, Goten, Vegeta, Bulma, Trunks, Gogeta, Elder Kai, Kabito Kai, Hercule, Pan, Giru, Majuub, Omega Shenron, Nuova Shenron, Naturon Shenron, Eis Shenron, Rage Shenron, Haze Shenron, and Oceanus Shenron. Sensei cards in this set included Black Smoke Dragon, Giru, Kabito Kai, Vegeta, Eternal Dragon, Omega Shenron.
