![Delta Reign ME06 Release Date & Card List Guide [2026]](https://samuraiswordtokyo.com/wp-content/uploads/2026/08/featured-delta-reign-me06-release-date-guide-1-1024x538.webp)
Full card list: Storm Emeralda (M6) card list → every card by number with rarity, individual card pages and in-stock PSA 10 prices.
The short version: Mega Evolution—Delta Reign (ME06), the sixth main set of the English Mega Evolution Series, is confirmed to release on November 6, 2026. One thing trips up a lot of searches for this set: Delta Reign is not a Japanese release. It is the English-language adaptation of a Japanese set that already exists — Storm Emeralda (M6), which launched in Japan on July 31, 2026 and has been fully revealed, card by card, since release.
That gap matters for buyers. Because Storm Emeralda is already out, the Japanese printings that Delta Reign is expected to draw from — headlined by Mega Rayquaza ex — are sitting in Tokyo right now, roughly three months before the English boxes exist. This guide covers what is officially confirmed about Delta Reign’s release, what the Japanese set tells us about the card pool, what is still unknown on the English side, and how to get the Japanese cards before November.
Confirmed: English release date November 6, 2026; official name Mega Evolution—Delta Reign (ME06), sixth set in the English Mega Evolution Series; one officially revealed English card, Mega Rayquaza ex, shown in the June 18, 2026 teaser alongside the release date. Inferred from the already-released Japanese sister set (Storm Emeralda, M6): a 113-card Japanese pool (76 main + 37 secret rares) headlined by Mega Rayquaza ex, with Mega Golisopod ex, Mega Golurk ex, Mega Malamar ex and Wishiwashi ex among the other featured cards. Still unconfirmed for English: official MSRP and final English card count — though as of August 19, 2026, hobby-shop retail pre-orders are live at around $199.90 per 36-pack booster box and $99.90 per Elite Trainer Box (retail asks, not an official MSRP) — see the dedicated section below before treating any number as official.
Delta Reign (ME06) Release Date: What’s Confirmed
Pokémon TCG: Mega Evolution—Delta Reign is the sixth main expansion of the English Mega Evolution Series, and its release date is one of the few Delta Reign facts that is fully official: November 6, 2026. The set was first teased on June 18, 2026 through the official Pokémon YouTube channel, which revealed the Delta Reign name, showed Mega Rayquaza ex as the cover card, and gave the November 6 date — announced together with the Japanese Storm Emeralda teaser and the TCG Pocket set “Ruler of the Skies,” which launches the same day.
As of August 19, 2026, the official tcg.pokemon.com Mega Evolution lineup still lists expansions only through ME05 Pitch Black — no Delta Reign expansion page is live yet, so only the release date, set name, and the single Mega Rayquaza ex reveal are official so far. What has changed since this guide first published: retail pre-orders went live at hobby shops in mid-August 2026, at premium prices — booster boxes (36 packs) around $199.90, with 3-per-customer limits at some shops, and Elite Trainer Boxes around $99.90 — while many retailers still list “Price TBA.” Those are hobby-shop retail prices, not an official Pokémon Company MSRP, and no official Pokémon Center pre-order has been confirmed.
| Date | Event |
|---|---|
| June 18, 2026 | Official teaser: Delta Reign name, Mega Rayquaza ex, November 6 date revealed |
| July 31, 2026 | Japanese sister set Storm Emeralda (M6) releases — full 113-card pool becomes public |
| August 10, 2026 (as of this guide’s first publication) | No official Delta Reign expansion page yet; retailer preorders already open |
| Mid-August 2026 | Hobby-shop retail pre-orders go live: ~$199.90 booster box (36 packs, some shops limit 3 per customer), ~$99.90 ETB; many retailers still “Price TBA” (as of August 19, 2026) |
| November 6, 2026 | Delta Reign (ME06) English release, alongside TCG Pocket “Ruler of the Skies” |
| November 20, 2026 | Build & Battle Kit release, per retail solicitations |
What Is Delta Reign? The English Side of Storm Emeralda
Here is the part that causes the most confusion: there is no Japanese set called Delta Reign. Delta Reign is the English-market set, built on the English side’s own numbering (ME01 through ME06). Japan’s Mega Evolution era uses a separate numbering line (M1 through M6). The two lines are parallel naming conventions for the same worldwide Mega Evolution era — not a renumbering of one into the other.
What actually happens is a localization pairing: Japan’s M6 Storm Emeralda, already released on July 31, 2026, becomes the English ME06 Delta Reign on November 6, 2026. This is the same relationship the previous set in the series followed: English ME05 Pitch Black (released July 17, 2026, headlined by Mega Darkrai ex) is the English adaptation of Japan’s M5 Abyss Eye (released May 22, 2026). In both cases the English set arrived one to three months after its Japanese counterpart, under a different set name and a different set code.
| Japanese set (M-line) | JP release date | English set (ME-line) | EN release date |
|---|---|---|---|
| M5 Abyss Eye | May 22, 2026 | ME05 Pitch Black | July 17, 2026 |
| M6 Storm Emeralda | July 31, 2026 | ME06 Delta Reign | November 6, 2026 |
The practical upshot for buyers: everything the Japanese Storm Emeralda set has already revealed — the headline card, the supporting Megas, the new mechanic — is the strongest available signal for what Delta Reign will contain, even though none of it is an official English card list yet. For a full side-by-side breakdown of exactly how the two versions are expected to differ (box structure, likely English rarity names, timing), see our dedicated Delta Reign vs. Storm Emeralda comparison guide rather than this page, which focuses on the release date and the buy-now case.
Mega Rayquaza ex in Context
Mega Rayquaza ex is the one card Delta Reign and Storm Emeralda officially share right now, and it is not a new character to the franchise — Rayquaza-focused chase cards have anchored TCG sets for two decades. The Mega Evolution treatment is the newest entry in a long line of high-demand Rayquaza printings, several of which are shown below for reference.
Mega Rayquaza EX — Emerald Break (JP) / Roaring Skies (EN), 2015
The 2015 Mega Rayquaza EX — first printed in Japan’s Emerald Break (XY6, pictured), then in English as Roaring Skies — defined a competitive era and remains one of the most recognized Rayquaza printings among collectors.
Shiny Mega Rayquaza EX — XY7 (2015)
The Shiny Full Art treatment from the same era shows how consistently Rayquaza gets a set’s premium alternate-art slot — a pattern the new Storm Emeralda MUR and SAR continue.

What’s Still Unknown About the English Release
It is tempting to treat the fully-revealed Japanese set as a stand-in for a fully-revealed English one, but several genuinely important details for Delta Reign have not been made official as of this guide’s publication. Listing them here is deliberate: none of the figures below should be repeated as confirmed facts.
| Detail | Current status |
|---|---|
| Booster box configuration | Not officially confirmed. Retailer listings and the now-live hobby-shop pre-orders show a 36-pack booster display, and the prior set (ME05) used 10 cards + 1 Basic Energy + 1 TCG Live code per pack — precedent and retail listings only, not an official spec. |
| MSRP (any Delta Reign product) | Not officially confirmed. Hobby-shop pre-orders opened in mid-August 2026 at around $199.90 per 36-pack booster box and $99.90 per ETB (as of August 19, 2026), but those are retail asks, not MSRP — many retailers still list “Price TBA,” and no official product page exists yet. |
| Final English card count | Unknown. English Mega Evolution sets have historically differed from the Japanese main-set count once secret rares and English-exclusive slots are added, but no official figure is published. |
| Elite Trainer Box contents / Pokémon Center exclusive ETB | Retailer-listed only (hobby-shop pre-orders around $99.90 as of August 19, 2026); whether a PC-exclusive ETB exists for this set (as it did for ME05) is unconfirmed, and no official Pokémon Center pre-order has been confirmed. |
| Additional card reveals | No official reveal schedule has been announced. |
One caution on card count specifically: 113 is the Japanese Storm Emeralda total, and English Mega Evolution sets have not simply copied the Japanese number in the past. Until Pokémon publishes an official Delta Reign set list, treat any specific English card count elsewhere as an estimate.
Get the Cards Now: Buy the Japanese M6 Set Before November
The practical case here is simple. Delta Reign is still months from shipping — hobby-shop retail pre-orders went live in mid-August 2026 at premium asks (about $199.90 per 36-pack box and $99.90 per ETB, as of August 19, 2026), but no product ships until November 6 and no official MSRP exists yet. Storm Emeralda, the Japanese set carrying the same Mega Rayquaza ex headline card and (by all current evidence) most of the same supporting cast, has been shipping in Japan since July 31, 2026. For English-speaking collectors who do not want to wait until November for a set that is functionally already out, the Japanese printing is the way to hold these cards first.
A few things worth knowing before buying the Japanese version instead of waiting for Delta Reign:
- Same headline card. Mega Rayquaza ex is the one officially confirmed link between the two sets — the Storm Emeralda printing gets you the same character and Mega Evolution treatment, in Japanese-language card text, ahead of the English release.
- Pack and box structure differ. Japanese boxes use smaller, cheaper packs than the English format is expected to use; see our Delta Reign vs. Storm Emeralda comparison guide for the structural breakdown.
- Real market data, not projections. Our card list and pull-rate coverage reflect real, live listings since Storm Emeralda is already on sale.
