Storm Emeralda Japanese Booster Box

Storm Emeralda is the Japanese MEGA expansion with set code M6, released in Japan on 31 July 2026 with Mega Rayquaza ex on the pack art. The English version, Delta Reign, does not arrive until 6 November 2026, so the Japanese box is the early way in. Each Storm Emeralda booster box contains 30 packs of 5 cards, so 150 cards per box.

Mega Rayquaza ex is the chase, with a Special Art Rare print (110/076) and the set's only Mega Ultra Rare (113/076). The other Special Art Rares are Mega Golisopod ex, Raikou ex and Mega Golurk ex, plus the full-art trainers Zinnia's Trust and Gilly. The set has 113 cards: 76 in the main set and 37 secret rares (12 Art Rares, 18 Super Rares, 6 Special Art Rares and the one Mega Ultra Rare). Japanese boxes pull far more consistently than English ones: a 30-pack MEGA-era box typically yields three Art Rares, a Super Rare trainer and a Super Rare or better Pokémon, alongside four or five Double Rare ex cards. The Special Art Rares and the Mega Ultra Rare are the chance pulls on top of that.
