Japanese Pokemon TCG M6 Storm Emeralda Booster Box 30 Packs Mega Rayquaza ex

The Japanese Pokémon TCG MEGA Expansion Pack “Storm Emeralda” (M6) was released on July 31, 2026, as the sixth installment of the Mega Evolution era. Each factory-sealed booster box contains 30 packs, with 5 randomly inserted cards per pack, for a total of 150 cards per box.

This set is headlined by Mega Rayquaza ex, a 280 HP Colorless-type Basic Pokémon. Its Ability, Champion's Roar, lets you look at the top 4 cards of your deck and attach a Basic Energy found there to this Pokémon when you play it onto your Bench. Its signature attack, Storm Emeralda, costs [R][L][C] and deals 50 damage multiplied by the number of Fire and Lightning Energy attached to all of your Pokémon in play, creating explosive damage potential.

Storm Emeralda features four Mega ex headliners in its main set: Mega Golisopod ex, Mega Golurk ex, Mega Malamar ex, and Mega Rayquaza ex. The set also introduces the first two-part “Legendary Summit” Stadium cards in the MEGA era, printed as connecting pairs. The master set spans 113 cards: a 76-card base set (62 Pokémon and 14 Trainers) plus 37 secret rares—12 AR, 18 SR, 6 SAR, and 1 MUR.
