Delta Reign Card List: Set Size, the Secret Rares and the Chase Cards to Watch

If you have been searching for a Delta Reign card list, the set behind it is Mega Evolution Delta Reign (ME6), the sixth expansion in the Pokémon TCG Mega Evolution series. It releases in English on November 6, 2026, headlined by the return of Mega Rayquaza ex. This guide does not run through every card one by one; it covers how the set is built, the 37 secret rares, the chase cards, and the sealed product you will be opening it in.

When Delta Reign releases in Australia

The English set lands on November 6, 2026, the date the official preview of the expansion's cards confirms. It is built on Japan's Storm Emeralda (M6), which released there on July 31, 2026, and the three-month gap is longer than usual because the 30th Celebration global launch claimed the September slot.

Before release day, Play! Pokémon prereleases run from October 24 to November 1 in participating stores, with the prerelease promos coming from Build & Battle boxes from October 24. Those prerelease events produce the first pack pulls of the set. On digital, Pokémon TCG Live gets the expansion a day early, on November 5.

Our release calendar tracks confirmed Australian release dates for every upcoming Pokemon TCG set, so Delta Reign's date sits alongside everything else coming to this market.

How many cards are in Delta Reign

The English set runs to 140 cards: 103 in the main set and 37 secret rares. It is not a straight copy of Japan's Storm Emeralda, which carries 76 main-set cards. The English expansion folds in 27 extra cards from Japan's MEGA Starter Decks, including Eevee ex, Zoroark ex and Meowscarada ex, taking the main set from 76 to 103.

That is also why some card lists still show 113 cards, which is Storm Emeralda's 76 main-set cards plus the same 37 secrets. Even Pokémon's own preview hedges, promising "more than 140 cards".

The 37 secret rares

The secret rare tier holds 37 cards. The two full card lists break it down slightly differently: PokeCottage's list counts 14 Illustration Rares, 16 Ultra Rares, 6 Special Illustration Rares and a single Mega Hyper Rare, while Pokéled's runs 14 Illustration Rares, 17 Ultra Rares and 6 Special Illustration Rares. Both land on 37.

The top of the ladder is not in dispute. The Mega Rayquaza ex Mega Ultra Rare is the only card of its tier and is already the rarest card in the Japanese Storm Emeralda set, with the six Special Illustration Rares rounding out the top.

One card moved tiers before release: the Kyogre Illustration Rare was cut from secret rare lists once it was confirmed as the set's Elite Trainer Box promo. It was drawn by Nurikabe, the same artist behind the Groudon Illustration Rare chase card from Paradox Rift.

The chase cards: Mega Rayquaza ex and the split Stadiums

Mega Rayquaza ex is the flagship, appearing in both Special Art Rare and Mega Ultra Rare form. It is card 084/103, illustrated by takuyoa, and the Pokémon's last playable card before this dated back to XY Ancient Origins in 2015. The Special Illustration Rare's preview artwork is by Kazuki Minami, winner of the 2024 Pokémon TCG Illustration Contest. Joseph Writer Anderson's secret rare list calls it a candidate for the most expensive card of the Mega Evolution era. TCG Watchtower's preview already has the gold Mega Ultra Rare tracking as one of the most anticipated pulls in the block on Japanese market prices. For the full ranking, our guide to the Delta Reign chase cards worth targeting orders them by Japanese market prices, with MUR, SAR, SR and AR values from Storm Emeralda data plus pull rate odds for Australian collectors.

Behind it sit three more Mega Evolution ex: Mega Golisopod ex, Mega Golurk ex and Mega Malamar ex, all of which debuted in the Mega Dimension DLC for Pokémon Legends: Z-A before making the jump to cardboard.

The set's other novelty is the split Legendary Stadium cards: three pairs, one for each Hoenn legendary, Kyogre, Groudon and Rayquaza. Each pair is two cards that cannot be played separately; you combine both halves from your hand and play them as a single Stadium, with the artwork merging across the join, and any booster pack containing one half also contains the other. Legendary Pyroduct is one of the first two-card Stadium cards to exist in the game. It shuts off both players' Evolution Pokémon Abilities while it is in play, hitting effects like Drakloak's Recon Directive and Alakazam's Psychic Draw. The Aarune Special Illustration Rare is built for the combo: it grabs up to three of any combination of Supporter and Stadium cards.

Sealed product: the booster box and the Elite Trainer Box

The Delta Reign booster box contains 36 booster packs, making it the main choice for opening the set at volume. The Elite Trainer Box comes with 9 booster packs, a promo featuring the Illustration Rare style Kyogre, sleeves, dice and energy.

What any of it sells for in Australia moves week to week, so the working number is a live one rather than a printed one. Our market prices calculate a genuine Australian market value per card and per sealed product from local sold and active listing data rather than converted US prices, with per-card pricing, recent movement and the cheapest live listings on each set page. And when sealed product lands at retail, our restock tracking sends alerts tuned to the Australian market so you know the moment booster boxes or ETBs hit the shelves.

One caveat that applies to any stock figure: a product counts as in stock when it was confirmed available at that retailer within the last 7 days. Availability at a big chain can change within minutes, so confirm on the retailer's own page before you rely on it.

How CardTracker.au helps you chase Delta Reign

We monitor Australian retailers and eBay Australia for trading card stock, restocks and price drops, and calculate a genuine Australian market price for singles and sealed product rather than converting a US figure. The market prices are built from local sold and active listing data, with per-card pricing, recent movement and the cheapest live listings for each set we track. Our release calendar carries confirmed Australian release dates for every upcoming Pokemon TCG set. Free restock and price-drop alerts land on Discord, Telegram and WhatsApp the moment a tracked retailer changes stock or price, each with a direct link to the listing, and a paid Premium community adds faster and more finely filtered alerts. On this guide's checks, that covers the three that matter: an Australian market figure rather than a converted US one, confirmed Australian release dates, and an alert the moment stock changes. The market prices and the free alerts cost nothing.

Before the November 6 drop, set up your free alerts and price each chase card in Australian dollars first.
