Pokemon Storm Emeralda Delta Reign M6 Japanese Booster Pack / Box

Pokémon TCG: Storm Emeralda (ストームエメラルダ) – Japanese Booster Pack (M6)

Japanese Release Date: 31 July 2026 | Set Code: M6 | Mega Evolution Era Series

English Equivalent: Delta Reign

Overview

Storm Emeralda (ストームエメラルダ / M6) is a flagship, high-octane main expansion set in the Japanese Pokémon TCG Mega Evolution series. Centered around the legendary sovereign of the skies, Mega Rayquaza ex, the set brings sweeping elemental storms and devastating dragon-type firepower to the competitive and collector landscape.

Unlike condensed High Class Packs, M6 follows Japan’s traditional 30-pack booster box format, delivering a massive, sprawling card pool packed with Art Rares (AR), Special Art Rares (SAR), and elusive high-tier secret ultra rares.

Boasting high-impact mechanics—including dual-element Energy synergies and innovative double-stadium dynamics—Storm Emeralda stands out as a flagship summer release that serves as the direct Japanese base for the English expansion, Delta Reign.
