The time itself has spiraled out of control! Monsters that can see the future. Monsters from a distant past. It’s a paradoxical journey through time and space gone awry. The Return of the Duelist contains a large number of new themes, such as Prophecy Monsters, a new type of Spellcasters that gain additional powers from Spell Book Cards; Geargia Monsters, machines that constantly bring new Geargia into play; Sweet Monsters, which go to the Deck instead of the Graveyard when destroyed. The more nostalgic fans and discerning players may also want the new cards from Yu-Gi-Oh! GX, which can combine with cards and themes that appeared in the Ra Yellow Mega Pack.
