One box contains 12 tins. Mirrored back to back, Yami Yugi and Seto Kaiba stand like giants over a series of iconic monsters from the Yu-Gi-Oh. anime series. Although they are the best duellists in the world, Yugi and Kaiba have always been a mirror image of each other. Yugi relies on the unity of his team and the power of friendship, Kaiba prides himself on his own almost unrivalled talent. As always, each tin contains 3 Mega Packs, each of which is guaranteed to contain several rarities. In this year's tin, some of the lower rarities have been removed to give you more rarities to search for, including a Quarter Century Secret Rare in each of the three packs. Be proud of your haul, because we've combined them into the higher rarities. This year's best-of-tin selection brings together popular and sought-after cards from a dozen recent booster sets, including Power of the Elements, Photon Hypernova, Cyberstorm Access, Duelist Nexus, Age of Overlord, Maze of Memories, Amazing Defenders, Wild Survivors, and many more. There are also brand new art versions of some of the most famous duelling cards, from Red & Ugly Black Dragon and Dark Mage to Harpy Bat and Raigeki. With 400 cards in the set, this box not only has something for everyone, but so much more. The 50 Quarter Century Secret Rares in this set are a trip down memory lane, featuring iconic monsters and images from decades of duels. In addition to the sixteen cards featured on the sides of the tins (more on that later.), there were just too many famous moments to leave out. That's why 34 more cards have been added to the Quarter Century Secret Rares, three of which you get in each tin. Total per tin: 3 Quarter Century Secret Rares 3 Prismatic Secret Rares 9 Ultra Rares 24 Commons.
