Delta Reign complete guide: Card List & Chase Picks

Delta Reign is a Pokémon Trading Card Game expansion in the Mega Evolution series, rather than a video game or downloadable title. The English set is scheduled to release on November 6, 2026, following the Japanese Storm Emeralda expansion released on July 31, 2026. Current card-list information identifies Delta Reign as ME6 and lists 113 cards, although final English numbering and product details should be checked when official listings are published.

The expansion centers on Mega Rayquaza ex and adds three other Mega Pokémon: Mega Golisopod ex, Mega Golurk ex, and Mega Malamar ex. The set also introduces paired Legendary Stadium cards, giving collectors and competitive players a new card presentation and deck-building consideration.

Video Highlights:

• Mega Rayquaza ex may become one of the strongest cards in the Mega Evolution format.
• Mega Golurk ex combines high damage with a restrictive hand-size ability.
• Mega Golisopod ex rewards players for placing damage counters before attacking.
• Mega Malamar ex scales its damage based on the opponent’s Benched Pokémon.
• Legendary Stadium pairs create new tactical effects and extended artwork.

The current card listing includes Pokémon, Supporters, Items, Stadiums, and special Energy cards. The most prominent high-rarity entries include Mega Rayquaza ex, Raikou ex, Zinnia’s Trust, Mega Golurk ex, and Mega Golisopod ex. Because the English release is still in the future as of August 21, 2026, treat market values and exact English numbering as provisional.

The four headline Mega Pokémon give Delta Reign a varied identity. Mega Rayquaza ex is the most explosive option, while Mega Golurk ex focuses on efficient damage with a demanding setup condition. Mega Golisopod ex offers a low-cost damage route against already-injured targets, and Mega Malamar ex specializes in punishing crowded Benches.

These cards should not be judged only by their listed attack damage. Energy acceleration, hand management, Stadium effects, and the number of Prize cards involved can determine whether a powerful attack is practical in a complete deck.

Mega Rayquaza ex

Mega Rayquaza ex is the set’s central card and has the strongest early competitive profile among the four featured Megas. Its ability attaches a basic Energy from the top four cards of your deck when you play it from your hand to the Bench. Its Storm Emerald attack then deals 50 damage for each Fire and Lightning Energy attached to all of your Pokémon.

This design encourages a broad Energy engine rather than placing every resource on Rayquaza alone. Ethan’s Ho-Oh and Iono’s Bellibolt are cited as useful partners because they can accelerate Fire or multiple Energy onto the field. The exact best list will depend on the format when Delta Reign becomes legal.

Mega Golurk ex

Mega Golurk ex offers an unusual damage-to-cost ratio: 300 damage for two Energy. Its restriction is equally important. If you have fewer than 10 cards in hand, its ability prevents it from attacking. Draw-heavy decks can satisfy this condition naturally, while certain Stadium effects may remove the ability from an Evolution Pokémon.

Mew is another possible workaround because it can copy an attack without copying the copied Pokémon’s ability. This creates a tactical distinction between using Golurk directly and reproducing its attack through another attacker.

Mega Golisopod ex and Mega Malamar ex

Mega Golisopod ex has a flexible damage profile. For one Grass Energy, it deals 60 damage, increasing to 220 if the opponent’s Active Pokémon already has damage counters. Risky Ruins can help establish those counters when Pokémon are Benched, though its effect does not apply against Darkness Pokémon.

Mega Malamar ex deals 70 damage for each opposing Benched Pokémon. Accompanying Flute can help increase the opponent’s Bench size, but the strategy depends heavily on the opponent’s board and may be less consistent than the other featured Mega attackers.

Legendary Stadiums are one of Delta Reign’s most distinctive additions. Each Stadium is split across two cards, with the pair forming a larger illustration when placed next to each other. The current set information identifies three themes: Legendary Ocean Trench, Legendary Summit, and Legendary Lava Lake.

The paired design resembles the classic two-card presentation used by LEGEND cards, but these are Stadium cards with their own deck-building rules. Both halves share the “Legendary” name, so the normal four-copy limit applies across the combined pair. The available information also indicates that a booster pack containing a Legendary Stadium includes both halves required to complete the artwork.

Legendary Summit is the clearest example of the mechanic’s strategic impact. When a Colorless Pokémon is Knocked Out by attack damage, the attacking player takes one fewer Prize card. This can reduce the Prize value of a multi-Prize target and may even make single-Prize knockouts yield no Prize cards under the stated condition.

However, the effect has meaningful limitations:

• You can play only four copies of the shared Legendary Stadium name.
• The limit applies across both halves, not separately to each card.
• If one half is in the Prize cards, you may be unable to complete the pair.
• A replacement Stadium can remove the active Legendary Stadium effect.
• The exact English wording should be checked when the cards are officially released.

The current Delta Reign structure includes 76 main-set cards and 37 secret rares. Reported categories include four Mega Rayquaza entries, six Pokémon ex, six Stadium cards, 14 Illustration Rares, 17 Ultra Rares, and six Special Illustration Rares. The web card listing also shows a Mega Ultra Rare Mega Rayquaza ex at #113/113.

The most desirable cards are expected to be concentrated around Mega Rayquaza ex, but collector interest also extends to supporting characters, legendary Pokémon, and alternate-art versions of the other featured Megas.

Current Chase Card Snapshot

The prices below are the values displayed in the referenced card listing at the time of collection. They appear to reflect current Japanese-market data and should not be treated as guaranteed English release prices, purchase recommendations, or long-term valuations.

For a broader reference, the Delta Reign ME6 card list includes regular, secret, Illustration Rare, Ultra Rare, and Special Illustration Rare entries. It also lists supporting cards such as Aarune, Tate & Liza’s Training, Heat Rotom ex, Altaria, Masquerain, and the three special Energy cards.

Delta Reign arrives in English on November 6, 2026. The Japanese Storm Emeralda release provides a useful preview, but collectors should separate confirmed set structure from estimated English pricing and numbering.

A practical approach is to decide whether your goal is competitive play, master-set completion, sealed collecting, or artwork collecting. Each goal benefits from a different purchase order and tracking method.

Recommended Research Order

1. Start with the official set announcement and product details. Confirm the release date, product lineup, and final English terminology.
2. Compare the Japanese preview with the English checklist. Use Storm Emeralda to identify likely cards, but record numbering differences separately.
3. Sort cards by collecting priority. Separate regular set cards, playable staples, Illustration Rares, and premium chase cards.
4. Review prices only as snapshots. Early values can move significantly as supply reaches the English market.
5. Recheck Legendary Stadium rules. Their shared-name limit and paired structure make them easy to miscount.
