Storm Emeralda (M6) Japanese Booster Box – Preorder

Preorder: Release is 31st of July. Shipment from Japan will be Monday 3rd of August. As soon as it arrives it will be shipped.

Pokemon TCG: Mega Evolution — Storm Emeralda (Japanese set code: M6) is the newest Mega Evolution era booster set from The Pokémon Company, releasing in Japan on July 31, 2026. This is a preorder listing — Storm Emeralda has not yet released. It is the Japanese source set for the upcoming English Mega Evolution set Delta Reign, which follows on November 6, 2026.

The set is headlined by Mega Rayquaza ex, marking the Sky High Pokémon's first Mega Evolution card of the modern era and its first new TCG artwork since the XY era. Confirmed reveals so far also include Mega Malamar ex, Mega Golisopod ex, Wishiwashi ex and Talonflame ex, alongside a connected Mega Gallade ex promo card. Storm Emeralda also debuts the split Stadium mechanic with Legendary Summit and Legendary Trench — each spread across two cards that must be combined from hand to be played as a single Stadium, a first for the Pokémon TCG.

The set also introduces a run of Zinnia-themed Trainer cards, tying the set's story to the Draconid lore that first introduced Mega Rayquaza in the core games. The Pokémon Company has not yet confirmed the full card count or rarity breakdown ahead of release; this listing will be updated once the complete card list is revealed.

Box contents: 30 booster packs per box. 5 cards per pack. 150 total cards per box (standard Japanese booster format). Language: Japanese. All card text is in Japanese. Condition: Factory sealed.

Ideal for Mega Rayquaza collectors, Draconid and Zinnia lore fans, and anyone who wants the Japanese originals of one of the Mega Evolution era's biggest 2026 releases ahead of the English Delta Reign set. Cards are randomised and specific pulls are not guaranteed. Recommended for ages 6 and up.
