Delta Reign: Mega Rayquaza ex Comes West on November 6, and Japan Already Priced It

Delta Reign, the English Pokemon TCG set built from Japan's Storm Emeralda, is confirmed for November 6 with Mega Rayquaza ex on the cover. Here is what makes this launch different: Japan has already been opening the same cards for two weeks, and the market moved fast, the top chase opened near 348,000 yen and asks now sit 40 to 50 percent lower. English preorders are live at hobby shops about 24 percent over list. This page is the English-side hub, everything confirmed, what Japan's prices say, and the honest preorder math, updated through launch.

What Is Confirmed About Delta Reign

• The date and the name. Delta Reign releases November 6, 2026, announced on Pokemon's official channels on June 18 alongside its Japanese counterpart, the name plays on Mega Rayquaza's delta motif.
• The place in the lineup. It is the sixth main expansion of the Mega Evolution series (you will see it coded ME06), following the fall calendar where 30th Celebration lands first on September 16, our hub tracks that set, then Delta Reign closes the year.
• The face of the set. Mega Rayquaza ex, a Colorless Basic with 280 HP and the Champion's Roar Ability, the character's first return to the TCG in the Mega era. The reveal wave also confirmed Mega Malamar ex, the Talonflame line, and Zinnia-themed Trainer cards, we covered the full preview when the set was announced.
• The card pool. The set is expected to carry the Japanese Storm Emeralda pool, 76 main-set cards plus 37 secret rares in Japan, with the exact English list and set size still unconfirmed, TPCi typically merges Japanese main sets with promo material, so treat the English count as TBD until the official list drops.
• The franchise push. The same June announcement introduced Mega Rayquaza to Pokemon TCG Pocket through the Ruler of the Skies expansion, which arrived July 28, this is a coordinated, franchise-wide Rayquaza fall, and that usually feeds card demand across every format.

Japan Already Ran Your Price Discovery

This is the section that saves you money. Because Japan gets the cards three months early, Storm Emeralda's market is a live preview of Delta Reign's chase list, and the first two weeks told a full story:

• The open. The Mega Rayquaza ex Mega Ultra Rare opened near ¥348,000 on July 31 and settled near ¥298,000, roughly $1,830, in week one, under lottery-constrained supply, we published the full ranked ladder at the time.
• The correction. As supply widened, the price came down hard, A-grade asking prices sit at ¥170,000 to ¥210,000 as of August 12, roughly $1,040 to $1,290, which is 40 to 50 percent below the open. Our week-one piece called those launch numbers a ceiling to watch, not a floor, and week two proved it.
• The ladder underneath. The Kazuki Minami Special Art Rare of Mega Rayquaza, drawn by a Pokemon Illustration Contest winner, held near ¥138,000 in week one. Raikou ex SAR was the riser, up more than 40 percent on day one. Zinnia's Trust debuted near ¥10,000 with Japanese trackers projecting ¥20,000 to 30,000 as the set matures.
• The supply signal. Sealed Japanese boxes traded at ¥23,000 to 25,000 against a ¥6,000 list price, four times printed price, and the top pull is reported at roughly one per 50 to 100 boxes, an estimate, but one that explains the chase premium.

The honest caveat: Japanese asks are not English prices, different print runs, different supply. But the direction travels, when Abyss Eye launched in Japan, its prices previewed the English Pitch Black chase list almost card for card. Expect the same map here, with the English market writing its own numbers on November 6.

Preorders Are Live, and So Is the Premium

English preorders opened at hobby retailers ahead of any wide retail wave, and the premium arrived with them. As of August 14, a 36-pack Delta Reign booster box preorders at $199.90 with a three-box limit at TCGora, with similar listings at other hobby shops, against the era's $161.64 standard box list price, that is about 24 percent over MSRP before a single pack exists, the level Pitch Black boxes reached only after they sold out at launch. Three honest rules for this window:

• A pre-release premium is a bet on scarcity that nobody can verify yet. Print-run depth for November sets is unknown, and November product historically restocks into December.
• The calendar is against panic. Every collector dollar between now and September 16 is being pulled toward 30th Celebration, and sell-out headlines from one set have a way of stampeding preorders on the next, we watched that exact sequence in the Pitch Black cycle.
• Price against list, not against hype. If preorders come back to $161.64 at major retailers in later waves, the early premium was the cost of impatience, not access.

Frequently Asked Questions

When does Delta Reign release?

November 6, 2026, worldwide, as the sixth main expansion of the Mega Evolution series. Its Japanese counterpart, Storm Emeralda, released on July 31, 2026, and 30th Celebration arrives between them on September 16. English preorders are already live at hobby retailers, with wider retail waves expected closer to launch.

What is the chase card in Delta Reign?

Mega Rayquaza ex leads the set, and Japan's market has already ranked the chase, the Mega Ultra Rare opened near 348,000 yen at the constrained July 31 launch and asks sit at 170,000 to 210,000 yen as of August 12, roughly $1,040 to $1,290. The Special Art Rare by contest winner Kazuki Minami and the Zinnia Trainer cards lead the tier below. English prices will not exist until packs open in November.

Should I preorder Delta Reign booster boxes?

Only at a price you would accept knowing restocks are likely. Early hobby-shop preorders sit near $199.90 per 36-pack box against a $161.64 list price, about 24 percent over MSRP for a set whose print depth nobody knows yet. November sets historically restock into December, so paying list on a later wave usually beats paying the early premium.

Where to Go From Here

Delta Reign is the rare launch where the price discovery happens in public, three months early, in another language, and the first two weeks already taught the lesson, launch prices are ceilings until supply says otherwise.
