Spell Ruler was the third Yu-Gi-Oh! booster set ever released! For years, you could only get your hands on these coveted packs as part of the Legendary Collection, but now, just in time to celebrate the 25th anniversary of the card game, they're being made available as a standalone booster! Spell Ruler was the first appearance of Ritual Spell Cards, Ritual Monsters, and Quick-Play Spell Cards like Mystical Space Typhoon. Trading Cards are FINAL SALE, no refund or exchange on this item.
