Storm Emeralda Booster Box

Storm Emeralda Booster Box - Japanese (M6)

The return of Mega Rayquaza ex, and it's every bit as big as it sounds. Storm Emeralda (M6) is one of the most hyped Japanese sets of 2026, taking players back to the Hoenn region with a lineup of Mega Evolution ex cards and stunning artwork built around the legendary sky dragon itself.

Each factory-sealed box holds 30 packs (5 cards per pack, 150 cards total), packed with chase cards including Mega Rayquaza ex, Raikou, Kyogre, Groudon and more. The set also debuts the Legendary Summit mechanic, paired Stadium cards that join together into one split artwork, so there's plenty here to keep both players and collectors happy. A serious box to rip or to hold sealed.
