Full card list: Storm Emeralda (M6) card list → every card by number with rarity, individual card pages and in-stock PSA 10 prices.
English Delta Reign doesn’t release until November 6, 2026, and there is no official English pull-rate sheet for it — the Pokémon Company has not published official pull rates for Delta Reign or for Storm Emeralda. But there is something close to a preview: Delta Reign is the English adaptation of a Japanese set that is already out, opened, and priced in the Japanese market.
That set is Storm Emeralda (M6), and our own Storm Emeralda pull-rate guide is built on the JP boxes we buy and sell out of Tokyo daily. This article uses that data to project what English Delta Reign players might reasonably expect — while being explicit, at every step, about what the Japanese numbers can and cannot tell you about an English product that hasn’t been printed yet.
Everything rate-related in this article is Japanese Storm Emeralda (M6) data, aggregated from community opening data and cited from our pull-rate guide. English Delta Reign’s pack contents, rarity mapping, and card count have not been officially published. Treat every number here as a JP baseline, not a Delta Reign guarantee.
What Delta Reign Actually Is (and Isn’t)
Worth clearing up first, because it trips people up: Delta Reign is not a new Japanese set. It’s the sixth main expansion of the English Mega Evolution Series — officially Pokémon TCG: Mega Evolution—Delta Reign, set code ME06 — and it is the English localization of the Japanese set M6 Storm Emeralda, which already released in Japan on July 31, 2026.
The two code systems run in parallel and don’t rename each other: M## is the Japanese line (M5 Abyss Eye, M6 Storm Emeralda, and so on), and ME## is the English line (ME01 Mega Evolution through ME05 Pitch Black to ME06 Delta Reign). Storm Emeralda becoming Delta Reign is a translation pairing, the same way every earlier Japanese Mega Evolution set became its own numbered English release.
Delta Reign was officially teased on June 18, 2026, alongside Storm Emeralda and the TCG Pocket set “Ruler of the Skies,” with the name, a Mega Rayquaza ex card, and the November 6 date confirmed. As of August 19, 2026, the official English expansion page for Delta Reign is still not live — tcg.pokemon.com’s Mega Evolution lineup ends at ME05 Pitch Black — and no official English card list, product lineup, or MSRP has been published. What has changed: hobby-shop retail pre-orders went live in mid-August, at around $199.90 per 36-pack booster box and $99.90 per Elite Trainer Box, with many retailers still listing prices as TBA — retail asks, not an official MSRP. Everything else we know about the eventual English card pool comes from the fact that its Japanese sister set is already fully revealed and on shelves.
For the fuller release-date breakdown — the June teaser, the JP→EN gap, and what’s confirmed versus not — see our Delta Reign release date guide. For a side-by-side on what carries over between the two versions of the set, see our Delta Reign vs. Storm Emeralda guide.
How Mega Evolution Localization Has Worked So Far
There’s one direct precedent for this pairing, and it’s recent: English ME05 Pitch Black (released July 17, 2026, headlined by Mega Darkrai ex) localizes Japanese M5 Abyss Eye, released May 22, 2026 — roughly a two-month JP→EN gap. Storm Emeralda to Delta Reign runs longer, about three months (July 31 to November 6) — PokeBeach’s explanation is that the special “30th Celebration” set (releasing September 16, 2026) took what would otherwise have been Delta Reign’s September slot, pushing the main expansion to November. That is PokeBeach’s reporting, not an official Pokémon statement.
The ME05 precedent also comes with a caution worth carrying into this article’s pull-rate section: English Mega Evolution sets have historically shipped with more cards than their Japanese main set. Retailer aggregators list ME05’s English card count at around 120, larger than JP M5’s main set. If that pattern holds for Delta Reign, the English card pool won’t be a clean 1:1 copy of Storm Emeralda’s 113 — and pull rates built on a different total card count don’t translate directly.
One more data point that argues for caution rather than confidence: of the 76-card Storm Emeralda main set plus 37 secret rares, exactly one card has been officially confirmed as part of English Delta Reign — Mega Rayquaza ex, shown in the June teaser. Bulbapedia’s tracking currently lists that English card as a Double Rare, a mainstream rarity tier — not the Mega Ultra Rare or Special Art Rare tier the Japanese art versions of the same character occupy. That single data point is a good illustration of the whole hedge this article is built around: the same character, same set pairing, can land at very different rarity tiers between the Japanese and English print runs. Nothing guarantees Storm Emeralda’s rarity structure carries over intact.
The JP Storm Emeralda (M6) Pull-Rate Picture
This is the part we can actually speak to directly. We handle Japanese Storm Emeralda sealed product daily out of Tokyo, and the numbers below are the same estimates behind our own Storm Emeralda M6 pull-rate guide, built from community opening data across a 30-pack Japanese box.
| JP rarity tier | Observed rate per 30-pack box | What it means in practice |
|---|---|---|
| RR Double Rare | ~6 per box | Guaranteed, the volume layer |
| AR Art Rare | ~4–5 per box | Effectively guaranteed, multiple times |
| SR Super Rare | ~2–3 per box | Reliable, 2 is the common outcome |
| SAR Special Art Rare | ~1 per 2–3 boxes | Roughly a coin flip per box |
| MUR Mega Ultra Rare | ~1 per 50–100 boxes | Case-level odds, not box-level |
Those rates sit inside a 113-card Japanese set: a 76-card base set plus 37 secret rares — 12 AR, 18 SR, 6 SAR, and 1 MUR. Storm Emeralda’s six SARs are Mega Rayquaza ex, Raikou ex, Zinnia’s Trust, Mega Golisopod ex, Mega Golurk ex, and Gilly, with values that range from ¥2,980 to ¥138,000 — so which SAR a box produces matters as much as whether it produces one at all. The set also headlines four Mega ex Pokémon — Rayquaza, Golisopod, Golurk, and Malamar — plus Wishiwashi ex, and introduces the series’ first two-part “paired” Legendary Stadium mechanic.
Worth repeating from that guide directly: the Pokémon Company has never published official pull rates for Japanese sets, and every figure above is aggregated community opening data, not a company disclosure. A week after release, secondary-market prices had already moved — the Rayquaza SAR had corrected to roughly half its day-one level while sealed box asks eased to the ¥17,500–20,000 range per our pull-rate guide’s week-one update. By August 19, 2026 the slide had continued: SNKRDUNK asks showed the Mega Rayquaza ex MUR around ¥135,000 for rank-A copies (lowest asks near ¥100,000), the SAR at ¥46,500–54,880, and shrink-wrapped sealed boxes around ¥16,900 (our own box listing is currently sold out) — a reminder that even confirmed JP numbers keep shifting as more boxes get opened.
What This Predicts — and Doesn’t Guarantee — for English Delta Reign
What the JP data reasonably suggests: Delta Reign will likely follow the same broad shape recent MEGA-series Japanese sets have followed — a guaranteed layer of lower rarities, a genuinely rare chase tier, and a headline Mega card sitting well above everything else in scarcity and price. Mega Rayquaza ex confirmed as the lead reveal, matching Storm Emeralda’s own headliner, supports that read. The paired-Stadium mechanic and its four headline Mega ex (Rayquaza, Golisopod, Golurk, Malamar) plus Wishiwashi ex are also reasonable expectations for the English pool, since the Japanese pool they’re translated from is fully public.
What it does not guarantee:
- Exact pull rates. No English MEGA-series set has ever shipped with official Pokémon Company pull-rate disclosures, any more than Japanese sets have. There is nothing to confirm Delta Reign’s numbers against, even after release.
- The rarity mapping. How Japanese AR / SR / SAR / MUR tiers translate into English rarities like Double Rare, Illustration Rare, or Special Illustration Rare for this specific set has not been published anywhere. The one confirmed data point — Mega Rayquaza ex listed as a Double Rare in English versus MUR in Japanese — argues against assuming a direct match.
- The card count. English ME sets have historically run larger than their JP counterpart (ME05’s ~120 vs. M5’s smaller main set). Delta Reign’s final English count is officially unknown.
- Pack and box contents. Retailer listings describe a 36-pack English booster box and a 9-pack Elite Trainer Box — now backed by live hobby-shop pre-orders (~$199.90 and ~$99.90 respectively as of August 19, 2026), but still unofficial until Pokémon publishes the real product page.

EN vs. JP Box Economics, at a Glance
The structural difference that matters most for economics: a Japanese Storm Emeralda box is 30 packs, while retailer listings put an English Delta Reign booster box at 36 packs — a different pack count on top of an unconfirmed rarity mapping, so JP box math can’t simply be scaled up to predict an EN outcome. Combine that with an English card pool that’s historically run larger than the Japanese one, and any EV comparison has real variables unsettled until Delta Reign has an official product page and enough opened boxes to generate real data.
We’d rather not guess at that comparison here with unofficial numbers. Our Delta Reign vs. Storm Emeralda guide covers what carries over and what doesn’t between the two versions of the set in more depth, and we’ll update it with real EN box economics once Delta Reign actually releases and English pull data exists to work from.
Skip the Wait: Buy Storm Emeralda from Japan Now
Here’s the practical angle underneath all the hedging above: you don’t have to wait until November 6 to open the Japanese version of this card pool. Storm Emeralda — the same 113-card set, the same Mega Rayquaza ex, the same paired-Stadium mechanic — is already released, already opened, and already trading across the Japanese market. We source and ship Storm Emeralda booster boxes ourselves out of Tokyo, shrink-wrapped and photographed condition-first before they travel — our own box listing is currently sold out (as of August 19, 2026), with restock alerts available on the product page, and the rest of our Japanese booster box collection remains live.
If you’re after specific Storm Emeralda singles rather than sealed boxes — including any of the six SARs or the Mega Rayquaza ex MUR — those move through our Quick Order page, which is also the fastest way to flag interest in Delta Reign singles once English copies exist to source. The sibling Mega Evolution sets — M1L, M1S, M2, M2A and the rest — are in our Mega Evolution (M) box collection. For everything else in this set — full card list, release-day pricing, chase-card rankings — our Storm Emeralda pull-rate guide and the linked Delta Reign chase cards guide are the two to read next.
Frequently Asked Questions
Is Delta Reign a Japanese or English set?
Delta Reign is English — the sixth main expansion of the English Mega Evolution Series (set code ME06), releasing November 6, 2026. It is not a Japanese set; there is no Japanese product called “Delta Reign.”
What is Delta Reign’s Japanese counterpart?
Storm Emeralda (M6), which released in Japan on July 31, 2026. Delta Reign is the English localization of that set, the way English ME05 Pitch Black was the localization of Japanese M5 Abyss Eye.
Will English Delta Reign have the same pull rates as Japanese Storm Emeralda?
Unconfirmed. No official pull rates have been published for either version, English booster boxes are retailer-listed at 36 packs versus Storm Emeralda’s 30, and the English rarity mapping for this set’s cards hasn’t been published. The Japanese data is the closest available preview, not a guarantee.
How many cards are officially confirmed for Delta Reign?
One — Mega Rayquaza ex, revealed in the June 18, 2026 teaser and listed by Bulbapedia as a Double Rare. The rest of the expected English card pool is inferred from Storm Emeralda’s fully revealed 113-card Japanese list, not officially confirmed.
What is Delta Reign’s release date?
November 6, 2026, alongside the TCG Pocket set “Ruler of the Skies” — the first simultaneous themed launch across both platforms. Japan’s Storm Emeralda released about three months earlier, on July 31, 2026.
Can I buy Storm Emeralda from Japan before Delta Reign releases in English?
Yes. Storm Emeralda has been on sale in Japan since July 31, 2026 — the same 113-card Japanese pool and the same Mega Rayquaza ex headliner that Delta Reign is localizing for November (the final English card count is still unconfirmed). Our own sealed box listing is currently sold out as of August 19, 2026, with restock alerts available on the product page.
Delta Reign (ME06) product details, English card count, and rarity mapping are unofficial as of this writing and subject to change once Pokémon publishes the official expansion page. Japanese Storm Emeralda (M6) pull-rate estimates are community-derived opening data from our own guide, not official Pokémon Company figures.
