Yu-Gi-Oh is a trading card game from Konami, similar to games like Magic The Gathering and the Pokemon Trading Card Game. It's based on the fictional game "Duel Monsters", which features in the Yu-Gi-Oh! manga and anime.
It was launched in 1999, and has been popular ever since, having sold tens of billions of cards over the last two decades.
Maze of Memories is the latest booster pack, featuring 67 cards. All are foiled to some extent, with 42 Rares, 15 Super Rares, and 10 Ultra Rares. 15 cards are also available as Collector's Rare, which features a rainbow-coloured reflective pattern.
