YGO Legendary Collection Kaiba - Rules of Play says:
Total Dueling domination never goes out of style for Seto Kaiba! This Spring, Legendary Collection Kaiba* brings together many of Kaiba’s most famous cards along with other powerful cards often used alongside them in a 100-card all-foil mega-set. Joining them are 5 brand new cards inspired by classic cards like Lord of D. and The Flute of Summoning Dragon! Topping it off in the Legendary Collection tradition is a hard-back, fold-up Game Board with a complete 1-player Duel Field on one side and an unbordered Kaiba art version on the other.
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
