Delta Reign doesn’t arrive until November 6, 2026. The cards in it went on sale in Japan on July 31, 2026.
If you’ve been following the Delta Reign leaks — the gold Mega Rayquaza ex, the Special Illustration Rares, the Raikou ex — every one of those cards already exists. They’re in Storm Emeralda, the Japanese version of the same set, which released on July 31, 2026. Delta Reign is the English printing of it, arriving about 14 weeks later.
This guide covers what Delta Reign is, when it lands, exactly how it differs from the Japanese release in box structure and rarity names, and what the live Japanese prices tell you about which cards will matter in November. We ship Japanese sealed product from Tokyo, so the Japanese figures here are the market we work in every day.
Delta Reign (ME06) is the English version of Japan’s Storm Emeralda (M6), releasing November 6, 2026. Same cards, different box math: Delta Reign is 36 packs × 10 cards, Storm Emeralda is 30 packs × 5 cards. The Japanese version is available now, and its day-1 singles prices are the best available preview of Delta Reign’s chase-card hierarchy.
Our M6 Storm Emeralda booster box (the Japanese version of Delta Reign) is currently listed at ¥11,040 (~$69); a shrink-damaged box is listed at ¥12,960 (~$82).
Delta Reign in One Line: It’s Storm Emeralda, Three Months Later
Delta Reign is the sixth main expansion of the Pokemon TCG’s Mega Evolution Series (set code ME06), headlined by Mega Rayquaza ex — and it is the English-language release of the Japanese set Storm Emeralda.
That relationship is the single most useful fact for anyone researching Delta Reign right now. The card pool, the artwork, the chase cards, and the mechanics are already public and already trading, because Japan has had the set since July 31. What changes between the two versions is language, box structure, rarity naming, and price level — not the cards themselves.
So when a leak account posts a “Delta Reign” gold Mega Rayquaza ex, what you’re looking at is the English print of a card that Japanese collectors were pulling on release day. The rest of this guide uses that head start.
Delta Reign Release Date and Products
Delta Reign releases in English on November 6, 2026. Here’s what has been confirmed about the products so far:
| Item | Detail |
|---|---|
| Set name | Delta Reign |
| Set code | ME06 (Mega Evolution Series, 6th expansion) |
| Release date | November 6, 2026 |
| Booster box | 36 packs |
| Booster pack | 10 cards |
| Headliner | Mega Rayquaza ex |
| Japanese counterpart | Storm Emeralda (M6), released July 31, 2026 |
Elite Trainer Box and other sealed configurations typically follow for English Mega Evolution sets, but official product details have not been announced. Update, August 19, 2026: retail pre-orders for Delta Reign went live at hobby shops in mid-August — booster boxes around $199.90 (some shops limit 3 per customer) and Elite Trainer Boxes around $99.90 — while many retailers still list prices as TBA. Those are hobby-shop retail asks, not an official MSRP, and no official Pokémon Center pre-order has been confirmed. Retail solicitations also list a Build & Battle Kit for November 20, 2026.
One thing worth flagging early: a 36-pack English box and a 30-pack Japanese box are not comparable on price alone. The next section handles that properly.
Side by Side: Delta Reign vs Storm Emeralda
Same set, two very different products. Here’s the structural comparison:
| Storm Emeralda (JPN) | Delta Reign (ENG) | |
|---|---|---|
| Release date | July 31, 2026 | November 6, 2026 |
| Set code | M6 | ME06 |
| Packs per box | 30 | 36 |
| Cards per pack | 5 | 10 |
| Cards per box | 150 | 360 |
| Box MSRP | ¥6,000 | Not yet announced (hobby-shop pre-orders ~$199.90, as of August 19, 2026) |
| Box market price (Jul 31) | ¥23,000–25,000 (~$141–$153) | — |
| Top rarity name | MUR Mega Ultra Rare | Gold / hyper-rare tier |
| Alt-art rarity | SAR Special Art Rare | SIR — Special Illustration Rare |
| Art rarity | AR Art Rare | IR — Illustration Rare |
The pack math is the part people get wrong. A Japanese pack holds 5 cards and a box holds 150; an English pack holds 10 and a box holds 360. English boxes contain more cards per box, but Japanese sets concentrate their hit structure differently — which is why comparing box prices without comparing hit rates tells you very little.
When you see “SIR Mega Golurk ex” in a Delta Reign leak, that is the English name for the Japanese SAR from Storm Emeralda — the same card, the same artwork, a different label.
The Chase Cards (and Their Japanese Names)
Everything revealed for Delta Reign so far maps directly to a Storm Emeralda card. Here’s the crosswalk, with the Japanese card already in hand:
Also confirmed for the English set: Special Illustration Rares of Mega Golurk ex and Mega Golisopod ex, plus eight Illustration Rares — the English counterparts of Storm Emeralda’s Art Rares, which include the Kyogre and Groudon that complete the Hoenn weather trio alongside Rayquaza.
The Japanese set also introduces the two-part “Legendary Summit” Stadium mechanic, played as a left-and-right pair. That mechanic carries over to Delta Reign, so English players get their first two-card Stadium in November.

What the Japanese Prices Tell You About Delta Reign
Japanese day-1 prices are the closest thing to a preview of which Delta Reign cards the market will chase. Here’s where the Japanese versions landed on release day:
| Card | Rarity (JPN) | JPN price, Jul 31 | USD approx. |
|---|---|---|---|
| Mega Rayquaza ex 113/076 | MUR | ¥298,000 | ~$1,830 |
| Mega Rayquaza ex 110/076 | SAR | ¥138,000 | ~$850 |
| Raikou ex 108/076 | SAR | ¥16,800 | ~$103 |
| Zinnia’s Trust 112/076 | SAR | ¥9,980 | ~$61 |
| Mega Golisopod ex 107/076 | SAR | ¥4,480 | ~$27 |
| Mega Golurk ex 109/076 | SAR | ¥2,980 | ~$18 |
Prices as of July 31, 2026, Japanese secondary market, at ¥163/USD.
Update — SNKRDUNK asks, August 19, 2026 (¥147/USD): those release-day numbers have since corrected substantially. The Mega Rayquaza ex MUR now asks around ¥135,000 for rank-A raw copies, with the lowest asks near ¥100,000 (~$680–918) — roughly 60% below the ¥300,000–350,000 range it held in early August. The Mega Rayquaza ex SAR asks ¥46,500–54,880 (rank B–A, ~$316–373), and shrink-wrapped sealed boxes ask around ¥16,900 (~$115). The relative hierarchy below still holds; the absolute numbers have moved.
Three things this tells you about November. First, the hierarchy inside the SIR tier is steep — the Rayquaza SAR is roughly 50 times the Golurk SAR, so “pulled an SIR” will mean wildly different things in Delta Reign. Second, Raikou ex is the sleeper: it climbed over 40% during Japanese release day on artwork demand plus competitive play, and that combination usually travels across languages. Third, Zinnia’s Trust is the supporter card to watch — trainer SIRs with strong character art have historically outperformed their initial pricing in English sets.
Two caveats worth stating plainly. English print runs are larger than Japanese ones, so Delta Reign prices will not match these numbers — historically Japanese chase cards trade at a 15–40% premium over their English counterparts. And these are release-day figures on a week-old set; the relative ranking is more durable than the absolute numbers.
Wait for Delta Reign, or Import Storm Emeralda?
Both are reasonable. It depends what you’re actually buying for.
Storm Emeralda (Japanese, available now)
- In hand roughly 14 weeks earlier
- Japanese textured foils and gold treatment, widely preferred by collectors
- Smaller print run than the English release
- 30 packs × 5 cards — denser hit structure per pack
- Historically carries a 15–40% premium over English
Delta Reign (English, November 6)
- English card text — readable at the table without a reference
- 36 packs × 10 cards — more cards per box
- Standard-legal in English-language tournaments
- Larger print run, generally lower per-card pricing
- Elite Trainer Box and other configurations likely to follow
The practical split we see in our own orders: players building English decks wait for November, because card text legibility and tournament legality matter to them. Collectors and resellers import the Japanese version, because the print quality, the earlier window, and the scarcity are the entire point.
If you’re in the second group, the one timing note that matters is that Japanese release-week prices are at their most volatile right now — decide your entry number before you shop rather than chasing the daily move.
What “Delta Reign” Actually Means
The name is a double reference, and it’s a neat one.
Delta points to Delta Stream, Mega Rayquaza’s signature ability — the air-current phenomenon that, in the games, nullifies the weather Groudon and Kyogre create. Reign points to Rayquaza’s role as ruler of the skies and the dominant member of the Hoenn weather trio.
Japan took the other half of the same idea: “Storm Emeralda” combines the storm imagery with Emerald, the Generation III game where Rayquaza takes the cover slot. Both names are pointing at the same card from opposite directions.
That trio framing shows up mechanically too. Kyogre and Groudon both appear as Art Rares in the Japanese set, and both reference “Legendary” Stadium cards in their attack text — the set is built around the three of them sharing a board.

Frequently Asked Questions
When does Delta Reign release?
Delta Reign releases in English on November 6, 2026. Its Japanese counterpart, Storm Emeralda, released on July 31, 2026 — about 14 weeks earlier.
Is Delta Reign the same set as Storm Emeralda?
Yes. Delta Reign (ME06) is the English release of the Japanese set Storm Emeralda (M6). Same card pool and artwork; the differences are language, box structure, rarity naming, and price level.
How many packs are in a Delta Reign booster box?
36 packs of 10 cards each, for 360 cards per box. The Japanese Storm Emeralda box holds 30 packs of 5 cards, for 150 cards.
What are the Delta Reign chase cards?
The gold Mega Rayquaza ex leads, followed by Special Illustration Rares of Mega Rayquaza ex, Raikou ex, Zinnia’s Trust, Mega Golurk ex, and Mega Golisopod ex, plus eight Illustration Rares. In Japan the equivalent Mega Rayquaza cards opened at ¥298,000 (MUR) and ¥138,000 (SAR).
Should I buy the Japanese version instead of waiting?
If you collect or resell, the Japanese version gives you a 14-week head start, smaller print runs, and the textured foil treatment collectors prefer — at a historical 15–40% premium. If you play in English-language tournaments, waiting for Delta Reign in November makes more sense.
