A 7-Eleven campaign commemorating the 25th anniversary of “Duel Masters” will run from 10:00 a.m. on October 15, 2026, through October 28. Customers who purchase two eligible ice cream items at once will receive one original clear card. The clear cards feature the trump creature cards of the protagonists from each generation and the 25th-anniversary key visual, for a total of five designs. They are available in limited quantities—the first 15 cards per store.
