Storm Emeralda M6 released in Japan on July 31, 2026, and within hours of the first shrink wrap coming off, a single card was listed at ¥298,000 (~$1,830) on Japanese marketplaces.
That card was the Mega Rayquaza ex MUR, which had opened at ¥348,000 the same morning. The Mega Rayquaza ex SAR climbed 17% before lunch, and sealed boxes were listed well above MSRP.

Storm Emeralda M6 by the Numbers
| Metric | Release-day figure |
|---|---|
| Box MSRP | ¥6,000 (~$37) — 30 packs × 5 cards |
| Box market price | ¥23,000–25,000 (~$141–$153) |
| Top card | Mega Rayquaza ex MUR (113/076) |
| Top SAR | Mega Rayquaza ex (110/076), which rose during the day while the MUR cooled |
| Set size | 76-card base set + 37 secret rares = 113 cards |
| English release (Delta Reign) | Scheduled for November 6, 2026 |
Two things stood out. The box price sat well above that of earlier MEGA-series sets, and the value was concentrated at the very top of the set, in one card: the Mega Rayquaza ex MUR.
What Is Storm Emeralda? (60-Second Recap)
Storm Emeralda is the sixth expansion in the MEGA era of the Japanese Pokemon TCG, built around Mega Rayquaza ex and a Fire + Lightning energy strategy. The set introduces a new mechanic — two-part Stadium cards, led by “Legendary Summit,” which you play as a left and right pair — and features four Mega ex Pokemon: Rayquaza, Golisopod, Golurk, and Malamar.
The base set runs 76 cards; the secret tier on top holds 12 Art Rares, 18 Super Rares (including six Goods and special energy SRs), 6 Special Art Rares, and a single Mega Ultra Rare — Mega Rayquaza ex, card 113/076.

Box Prices: The Pre-Release Peak and the Correction
The short version: boxes opened well above list price but meaningfully below the pre-release peak.
| Date | Japanese market price (sealed box) | Note |
|---|---|---|
| Early July 2026 | ~¥36,000 | Pre-release peak |
| July 21 | ~¥32,000 | Cooling from the early-July peak |
| July 29 | ~¥23,950 | Lowest pre-release listings (SNKRDUNK) |
These figures come from Japanese secondary-market data (SNKRDUNK listings and shop pricing).
Storm Emeralda boxes were listed heavily before release: sealed boxes reached around ¥36,000 weeks before anyone had opened a pack. That pre-release premium then corrected by roughly 30%.
Even after the correction, Storm Emeralda boxes opened at about twice the price of previous MEGA-series sets, which opened around ¥11,000.
A correction from a speculative peak is normal — and from a buyer’s perspective, a box opening below its pre-release high is a healthier entry than one opening above it.
Chase Card Values: MUR, SAR, and AR Prices
One card dominated this set’s value, but prices moved across every rarity tier that day.
Mega Rayquaza ex MUR — 113/076
The Mega Ultra Rare Mega Rayquaza ex opened that morning around ¥348,000 (~$2,135) on Japanese marketplaces and was listed at ¥298,000 (~$1,830) by the evening, after an intraday cooldown.
Early prices for a card this scarce rest on a handful of listings and can swing hard in both directions, so treat them as dated snapshots, not quotes.
Special Art Rares — the day’s biggest movers
| Card | Rarity | Opening price | Evening price | USD approx. |
|---|---|---|---|---|
| Mega Rayquaza ex (110/076) | SAR | ¥118,000 | ¥138,000 ▲ | ~$850 |
| Raikou ex (108/076) | SAR | ¥11,800 | ¥16,800 ▲ | ~$103 |
| Zinnia’s Trust (112/076) | SAR | ¥10,800 | ¥9,980 | ~$61 |
| Mega Golisopod ex (107/076) | SAR | — | ¥4,480 | ~$27 |
| Mega Golurk ex (109/076) | SAR | — | ¥2,980 | ~$18 |
Japanese shop and marketplace listings; ▲ marks a price that rose during the day.
The SAR Mega Rayquaza moving from ¥118,000 to ¥138,000 within the day was the notable price story — while the MUR cooled off its opening spike, the SAR strengthened.
Raikou ex SAR (108/076) was the sleeper of the day, up over 40% from its opening listings.
Art Rares — the legendary duo leads
| Card | Rarity | Opening price | Evening price | USD approx. |
|---|---|---|---|---|
| Kyogre (080/076) | AR | ¥1,980 | ¥2,780 ▲ | ~$17 |
| Groudon (084/076) | AR | ¥1,980 | ¥2,780 ▲ | ~$17 |
| Mega Rayquaza ex (095/076) | SR | ¥6,980 | ¥7,980 ▲ | ~$49 |
Kyogre and Groudon AR climbed together, both about 40% from their opening listings; with Rayquaza, they make up the Hoenn weather trio. The Mega Rayquaza ex SR (095/076) also rose, from ¥6,980 to ¥7,980.
From Leaks to Shelves: How Storm Emeralda Was Revealed
Storm Emeralda’s prices followed a six-week reveal cycle.
| Date | Event |
|---|---|
| Mid-June 2026 | Official reveal: set name, Mega Rayquaza ex, and the two-part “Legendary Summit” Stadium mechanic announced |
| Late June–July | Card reveals roll out; leak accounts circulate early pack and card images; pre-release box listings climb |
| July 24 | Official full card list published — all secret rares confirmed, including the MUR |
| July 30 | Final pre-release day; boxes listed at ¥23,950 |
Before the July 24 full list, which cards would get SAR treatment was still open to speculation. The list confirmed 6 SARs and a single MUR, and the final pre-release box listings sat well below the earlier pre-release highs.
One note on leak images: unofficial early images circulated widely during the reveal cycle, and they were largely accurate this time, but official confirmations are the reveal source to rely on for purchasing decisions.
Pull Rates & What a Box Actually Contains
As of July 31, 2026, official pull rates had not been published. Community estimates for a Storm Emeralda box rest on opening data from the earlier MEGA-series sets Mega Symphonia and Abyss Eye; treat them as directional, not confirmed figures.
| Rarity | Estimated rate |
|---|---|
| AR | ~4–5 per box |
| RR | ~6 per box |
| SR | ~2–3 per box |
| SAR | ~1 per 2–3 boxes |
| MUR | ~1 per 50–100 boxes |
The value structure of a box works like this: ARs and SRs provide the base return, a SAR hit is what pushes a box meaningfully into the black, and the MUR is a lottery ticket on top rather than something to price in. That is the standard value structure for modern Japanese sets. If you’re buying to hold rather than to open, the calculus is different.
After the Release: Earlier MEGA Sets and How to Buy
- Mega Symphonia and Abyss Eye both hit their highest sealed-box prices around their own releases, then stabilized in the ¥9,100–14,000 range.
- Storm Emeralda in its first week: on August 7, 2026, the lowest box asks on Japanese marketplaces were around ¥20,800, Mega Rayquaza ex SAR asks were ¥65,000–88,000, and the MUR asks were ¥300,000–350,000.
Three approaches buyers took, depending on what they wanted:
- Opening for the experience: the appeal of opening a box was the shot at the set’s SARs and the MUR, and the community moment around a new set only happens once.
- Collecting specific cards: watching the specific card you wanted was the patient route.
- Sealed holders: box asks moved lower after the release, so deciding an entry price in advance mattered more than chasing.
Whichever route you take, set your target price before you shop — and avoid chasing candles.
