Delta Reign Chase Cards: An English Release Watchlist

As of October 8, 2026, Delta Reign has no English card prices to report, because the set does not reach stores until November 6, 2026. What exists is a size breakdown from The Pokemon Company International (TPCi), 15 cards shown by number in its announcement and card features, and a Japanese set with the same headliner, Storm Emeralda, on sale since July 31, 2026.

TPCi names Mega Rayquaza ex as the headliner and counts 37 cards across its illustration rare, ultra rare and special illustration rare tiers. By October 8 it had placed only two cards in those tiers: Aarune, a special illustration rare, and Enamorus, an illustration rare.

What is confirmed as of October 8

Every row below comes from a TPCi page dated on or before October 8, 2026.

TPCi introduces the rarity counts as noteworthy cards the expansion includes, not as a complete rarity table, so a tier it does not list may still exist. The rarity symbols guide explains what each tier means.

A Legendary Stadium is two Stadium cards that form one extended artwork side by side, and booster packs holding one contain both halves.

The watchlist by confidence

TPCi's August 20 announcement shows the four Mega Evolution ex as card images numbered 11, 47, 69 and 84 of 103, each marked with the two black stars of a double rare, plus the two halves of the Legendary Summit Stadium (96 and 97).

Its card features of September 21 and October 5 added ten more: Heat Rotom ex (DLR 23), Hypno (44), Groudon (53), Kommo-o (75), Delibird (79), Kecleon (83), Legendary Pyroduct (94 and 95), Zinnia's Trust (103), Enamorus (110) and Aarune (139). Every card shown except Enamorus and Aarune is numbered 103 or lower and marked common, uncommon, rare or double rare. Those two sit above the printed total of 103, where secret rares are numbered.

The labels describe how firmly each fact is sourced, not where a card will rank on price. No card in the table has an English price.

How Storm Emeralda maps to Delta Reign

The Pokemon Company's Japanese product page lists Storm Emeralda for July 31, 2026, at 200 yen for a five-card pack, headlined by Mega Rayquaza ex. TPCi's August 20 announcement and media alert and its October 5 card feature never mention Japan or Storm Emeralda.

The link is an inference from the cards. Thirteen of the 15 cards TPCi has shown share a name with a card in Cardboard Alpha's catalog of the Japanese set, including all four Mega Evolution ex and Legendary Summit. Delibird is not in Storm Emeralda but is in all three Japanese Starter Set ex products released the same day.

Legendary Pyroduct has no same-name card, since Japan's three two-card Stadiums are Legendary Summit, Legendary Marine Trench and Legendary Lava Tube. Of the two English Legendary Stadiums shown by October 8, only Legendary Summit shares a Japanese name.

That fits TCGplayer's March 5, 2025 guide, which says an English release may merge the card lists of two or more Japanese releases. The same guide says Japanese Art Rares and Special Art Rares are called Illustration Rares and Special Illustration Rares in English. The English list therefore cannot be read straight off the Japanese one.

Storm Emeralda's top tiers in the catalog are the Japanese cards to compare against each English reveal:

• Special Art Rare (6): Mega Golisopod ex, Raikou ex, Mega Golurk ex, Mega Rayquaza ex, Aarune and Zinnia's Trust (numbers 107 to 112).
• Mega Ultra Rare (1): Mega Rayquaza ex (number 113).
• Art Rare (12): Masquerain, Growlithe, Magmortar, Kyogre, Electivire, Pincurchin, Enamorus, Groudon, Inkay, Azurill, Altaria and Kecleon (numbers 77 to 88).
• Mega Rayquaza ex versions: four in Japan, at Double Rare, Super Rare, Special Art Rare and Mega Ultra Rare.

TPCi's six special illustration rares match the count of Japan's six Special Art Rares, and Aarune is a Special Art Rare in Japan too (number 111). TPCi has placed only that one of the six. Its 14 illustration rares also compare with Japan's 12 Art Rares, so the two lists are not identical.

Three English Mega sets on October 8

Delta Reign has no English price, so the nearest evidence is how three English Mega Evolution sets with the same chase-tier shape, Perfect Order, Chaos Rising and Pitch Black, priced their top cards on October 8, 2026. Each has six special illustration rares and one Mega Hyper Rare in Cardboard Alpha's catalog.

SIR is special illustration rare, IR illustration rare, UR ultra rare, MHR Mega Hyper Rare. Prices are Cardboard Alpha evaluated prices for English, unstamped, raw Near Mint copies on October 8, 2026. Delta Reign counts are TPCi's August 20 list; the other counts come from the catalog.

In all three sets the most expensive unstamped card was a Mega Evolution ex. In Pitch Black and Chaos Rising, the top two cards were one Mega ex in its special illustration rare and Mega Hyper Rare forms: Mega Darkrai ex at $145.00 and $139.99, and Mega Greninja ex at $130.00 and $125.58.

In Perfect Order the Mega Zygarde ex Mega Hyper Rare led at $99.79, ahead of Meowth ex's special illustration rare at $89.31.

Below the top, prices dropped sharply. The second most expensive special illustration rare priced at 44 percent of the most expensive in Pitch Black ($63.69 against $145.00), 31 percent in Chaos Rising ($40.00 against $130.00) and 47 percent in Perfect Order ($42.24 against $89.31).

Pitch Black's and Chaos Rising's top prices rest on 11 and 14 recorded same-day sales. Perfect Order's top two, $99.79 and $89.31, rest on only two and three same-day sales, each blended with the 30-day median and the best delivered ask. Pitch Black's $139.99 Mega Hyper Rare is blended the same way from three.

The card tiles open Cardboard Alpha's own pages, which update on their own schedule, so the figures they show can differ from the October 8 prices quoted here.

This is history, not a forecast. Delta Reign's tiers differ in size, TPCi has listed no Mega Hyper Rare for it, and it has no English prices. The Pitch Black set page holds the card-by-card picture for the newest of the three, and the Mega Evolution era value guide compares all six earlier sets.

What stays unknown before release

Four things cannot be settled until English cards exist.

• Mega Rayquaza ex in English: the cited TPCi pages show only its double rare (84 of 103), and Japan prints four versions that the English set may not match. The Rayquaza price guide covers the older Mega Rayquaza card.
• A Mega Hyper Rare: Perfect Order, Chaos Rising and Pitch Black each have one, Japan's set has a single Mega Ultra Rare (a Mega Rayquaza ex), and TPCi's list names no Delta Reign card at that tier.
• Pull rates: they are measured from opened packs, and TPCi's prerelease events, the first scheduled play with the set, begin October 24, 2026. How pull rates are measured is covered separately.
• Prices: none exists, and Japanese prices do not carry across, because Japanese and English printings of the same art are priced independently. A same-art comparison of Japanese and English cards shows the gap running both ways.

Until the English list is public, the useful record is the dated one above: TPCi's counts, 15 cards by number and Storm Emeralda's top tiers, each labeled by how firmly it is known. Cardboard Alpha's screener tracks the released sets, and Delta Reign will need its own dated read once English cards sell.
