Buu Saga introduced the concept of Alternate Dragon Balls (Dende, in this expansion), which were played exactly like the originals, but with different effects. Also introduced was Fusion, which allowed players to remove two specific Personalities from play in order to play a much more powerful Personality. A new kind of high-tech card was introduced for the personalities, called "gate-fold." It would have a normal card face on the outside, and then open up for a new card on the inside. Finally, the introduction of a Bee Personality card broke the Majin-only Allies rule, allowing him to be an Ally to Majin Buu. This was the final Starter Deck set released for the DBZ CCG. It introduced the only booster pack "Uber Rares", though their rarity was such that they seemed easier to get than the Ultra Rares. The Buu Saga was released in Booster Packs, as well as Hero and Villain Starter Decks. Personality cards in this set included Goku, Gohan, Goten, Kid Trunks, Piccolo, Krillin, Dende, Hercule, Oolong, Bee, Korin, Gotenks, Majin Babidi, Majin Dabura, Majin Vegeta, and Majin Buu. Sensei cards in this set included Master Roshi and Elder Kai.
