The Storm Emeralda booster box (M6) released in Japan on July 31, 2026, and it’s the kind of box that gets asked about constantly: four Mega ex headliners in one set and a brand-new two-part Stadium mechanic.
M6 Storm Emeralda is a 113-card set (76 numbered base cards plus 37 secret rares) released July 31, 2026, built around four Mega ex headliners — Mega Golisopod ex, Mega Golurk ex, Mega Malamar ex and Mega Rayquaza ex. The M6 Storm Emeralda Booster Box and the Damaged Box listing (update: currently sold out — restock requests via Quick Order) are both currently listed, so check both product pages before choosing.
- Store status: the Sealed regular box and the Damaged Box listing are both currently listed.
- The full set checklist is on the Storm Emeralda (M6) card list page.
- Card-by-card detail: Storm Emeralda pull rates and best cards.

What’s in a Storm Emeralda Booster Box
Storm Emeralda is the official EN name for this set; the Japanese name is “ポケモンカードゲーム MEGA拡張パック「ストームエメラルダ」”, and it carries the set code M6. It’s the sixth entry in the MEGA expansion line.
| Item | Value |
|---|---|
| Set code | M6 |
| Release date (JP) | July 31, 2026 (Friday) |
| Packs per box | 30 |
| Cards per pack | 5 |
| Pack price (tax incl.) | ¥200 |
The ¥200 per-pack figure is store-sourced rather than confirmed on the official Pokémon Card site. The set totals 113 cards: a 76-card numbered base list (62 Pokémon, 14 Trainers) plus a 37-card secret-rare tier — 12 Art Rare (AR), 18 Super Rare (SR), 6 Special Art Rare (SAR) and 1 Mega Ultra Rare (MUR).
Two things set this release apart from a standard expansion pack. First, it introduces a new two-part “Legendary Summit” Stadium mechanic — a left-and-right paired Stadium card printed as a set. How that works is covered in our two-part Stadium cards guide. Second, Storm Emeralda doesn’t include any Basic Energy cards — a detail specific to this Japan-only release.
Four Mega ex headline the set’s base printings: Mega Golisopod ex (009/076), Mega Golurk ex (033/076), Mega Malamar ex (048/076) and Mega Rayquaza ex (058/076). Beyond those four, the base list also carries Heat Rotom ex, Wishiwashi ex, Raikou ex and Talonflame ex.
Each of these is the base-set printing of its Mega ex — the numbered card you’ll pull most often. Several also have higher secret-rare printings in the 095–113 range.

Storm Emeralda Chase Cards
| Card | Rarity | Number |
|---|---|---|
| Mega Rayquaza ex | MUR | 113/076 |
| Mega Rayquaza ex | SAR | 110/076 |
| Raikou ex | SAR | 108/076 |
| Zinnia’s Trust | SAR | 112/076 |
| Mega Golisopod ex | SAR | 107/076 |
| Mega Golurk ex | SAR | 109/076 |
| Mega Rayquaza ex | SR | 095/076 |
| Kyogre | AR | 080/076 |
| Groudon | AR | 084/076 |
Mega Rayquaza ex appears at SR (095/076), SAR (110/076) and MUR (113/076); the other named SARs are Mega Golisopod ex (107/076), Raikou ex (108/076), Mega Golurk ex (109/076) and Zinnia’s Trust (112/076), and Kyogre (080/076) and Groudon (084/076) are the named ARs.
Mega Rayquaza ex has printings across three different secret-rare tiers — SR, SAR and the set’s single MUR — which is why it anchors the top of the set’s rarity ladder. The secret pool holds six SAR slots in total; besides the five named SARs (Rayquaza, Raikou, Zinnia’s Trust, Golisopod and Golurk), the sixth is covered in our Storm Emeralda pull rates and best cards article.
Mega Rayquaza ex (058/076), Mega Golisopod ex (009/076) and Mega Golurk ex (033/076) each have a base printing separate from their SAR/MUR chase versions, and Mega Malamar ex (048/076) is the fourth Mega ex headliner among the base printings.
Zinnia’s Trust is the set’s one Trainer-card SAR in the named chase pool — if you want more on Zinnia as a character across her Japanese printings, see our Zinnia Pokémon cards guide.
