M6 Storm Emeralda - Booster Box

M6 Storm Emeralda is the seventh mainline MEGA Series expansion, built around Mega Rayquaza ex and a return to Hoenn. The set name references Mega Rayquaza's signature attack - the same convention as Emerald Break, the 2015 Japanese set that introduced Mega Rayquaza and took its name from that card's attack. Eleven years on, the naming is a deliberate echo.

At 113 cards (76 main set plus 37 secret rares), it is the smallest mainline MEGA set since the series opened. Four Mega Evolutions anchor it - Mega Rayquaza ex, Mega Golisopod ex, Mega Golurk ex and Mega Malamar ex. Three split Stadiums run at 071-076, each printed across two cards that combine into a single Stadium and a single continuous illustration, a first for the game. A Hoenn sub-theme carries through Zinnia's Trust, Aarune and Tate & Liza's Training, with Kyogre and Groudon art rares completing the weather trio around Rayquaza. Mega Rayquaza ex takes the MUR and an SAR, with Mega Golisopod ex, Raikou ex, Mega Golurk ex, Aarune and Zinnia's Trust filling out the Special Art Rare pool.

A strong pick for Rayquaza collectors and anyone building across the full MEGA Series run. The English equivalent releases as Delta Reign on November 6, 2026.
