Each Legendary Collection Kaiba box set contains:
- 3 Legendary Collection Kaiba Mega Packs. Of course, there's no way that Kaiba would settle for normal Mega Packs, so each of these Mega Packs contains 4 Secret Rares and 6 Ultra Rares for a total of 10 foil cards per pack (that's 30 cards per box)!
- 5 new cards based on some of Kaiba's famous cards like Lord of D., including a new Fusion Monster to Summon with The Fang of Critias!
- 1 Game Board
