For Yu-Gi-Oh! collectors and players, this is the Mathematician card from the Dragons of Legend set. It's a Secret Rare – that's one of the higher rarities, so the card has that shiny, holographic foil pattern. This listing is for the 1st Edition version, which is usually more sought after. The card number is DRLG-EN023. It comes as a single card, not a full pack. Condition is new and ready for your deck or collection. Mathematician is a pretty useful card in certain strategies, so it's popular for gameplay too. Whether you're completing a set, building a deck, or just love collecting cool cards, this is a solid addition. Make sure to check the photo for exact appearance. A must-have for serious Yu-Gi-Oh! fans.
