Storm Emeralda (m6)

Storm Emeralda (Japanese: ストームエメラルダ Storm Emeralda) is the name given to the sixth expansion of cards released during the Japanese Pokémon Trading Card Game's MEGA Series. This set continues to introduce Mega Evolution Pokémon ex and Trainer cards from the video game. Instead of being based on Pokémon Legends: Z-A, this set is primarily based on Pokémon Omega Ruby and Alpha Sapphire, featuring characters from the games and a heavy focus on Mega Rayquaza ex as the central Pokémon, although Mega Evolution Pokémon from Pokémon Legends: Z-A still make an appearance.

A new gameplay mechanic introduced in this expansion is paired Stadium cards that feature one artwork split into two. These pairs of Stadium cards are played together as one large card, but otherwise follow the same rules as other Stadium cards.

Release Date: July 31, 2026
