Delta Reign — Where to Buy & Live Stock Tracker (2026)

The sixth expansion in the Mega Evolution era (set code ME06), built around Mega Rayquaza ex descending from the sky over the Hoenn skyline. Delta Reign adapts Japan's Storm Emeralda expansion and contains over 135 cards: 4 Mega Evolution Pokémon ex, 6 further Pokémon ex, over 20 Trainer cards, 14 Illustration Rares, 17 Ultra Rares and 6 Special Illustration Rares. It also introduces Legendary Stadiums — paired Stadium cards with artwork that connects across both halves. Pre-release events run October 24 to November 1, 2026.

Series: Mega Evolution · Release Date: 2026-11-06

The Kyogre Illustration Rare is worth calling out: it was cut from the English main set and appears only in the Elite Trainer Box. If you want that card, the ETB is the only sealed product that contains it.

Delta Reign contains 6 Special Illustration Rares, 14 Illustration Rares and 17 Ultra Rares. Based on the Japanese Storm Emeralda expansion it adapts, the cards expected to carry the set:

1. Mega Rayquaza ex SIR — The defining chase card and the reason this set will sell. Rayquaza is one of the most consistently valuable Pokémon in the entire TCG, and Mega Rayquaza ex arrives as a Colorless Basic with 280 HP and the Champion's Roar Ability. Every prior Rayquaza alternate art has commanded a premium; expect this one to anchor the set's value.
2. Mega Golisopod ex SIR — The Bug/Water Mega brings an aggressive, armoured design. A strong secondary chase behind Rayquaza.
3. Mega Golurk ex SIR — Ground/Ghost typing with a distinctive silhouette. Golurk has a devoted niche following that punches above its popularity ranking.
4. Mega Malamar ex SIR — The Dark/Psychic Mega rounds out the four Mega Evolution ex cards with an inverted, unsettling art direction.
5. Zinnia (Supporter SIR) — Zinnia is inseparable from the Rayquaza and Delta Episode storyline in Omega Ruby and Alpha Sapphire. Trainer SIRs tied to beloved characters hold value exceptionally well, and this is the thematic heart of the set.
6. Talonflame ex — A returning fan favourite with an alternate art treatment expected among the Ultra Rares.
7. Raikou ex — Legendary beast appeal plus competitive relevance. Raikou cards move on both collector and player demand.
8. Legendary Stadium pairs — Six Stadium cards forming three pairs, each with artwork that connects across both halves. Both cards of a pair appear together in any booster pack containing one. Connecting-art cards drive completionist demand: collectors want the pair, not the single.

The set also includes special Energy cards adapted from Storm Emeralda. At just over 135 cards, Delta Reign is a mid-size expansion — meaningfully smaller than Ascended Heroes' 295, which concentrates pull odds around the headline cards.

Delta Reign occupies an unusual slot in the 2026 calendar. The 30th Celebration global launch claimed the September release window, pushing this expansion to November 6 — a three-month gap from the Japanese Storm Emeralda release on July 31, rather than the usual two. That delay has two consequences worth understanding before you buy.

Key investment considerations:

• Rayquaza factor: Rayquaza is a top-tier collector Pokémon with a long track record of premium pricing across Roaring Skies, Evolving Skies and beyond. Evolving Skies became one of the most valuable modern sets largely on the back of its Rayquaza chase card. Mega Rayquaza ex is the single strongest argument for this set.
• Extended reveal window: The three-month gap means European buyers can see Japanese Storm Emeralda pull rates and secondary prices before committing money. That is real information the usual two-month cadence does not give you — use it.
• Anniversary hangover: Delta Reign launches while collector budgets are still absorbing the 30th Celebration waves running through November and December. Softer launch demand can mean better availability at retail, and historically that has been a buying opportunity rather than a warning sign.
• ETB-exclusive Kyogre: A chase card locked behind a single SKU reliably lifts demand for that SKU. Expect the Elite Trainer Box to sell through faster than its pack count alone would suggest.
• Legendary Stadiums: A genuinely new mechanic with connecting artwork. New mechanics in their debut set tend to attract collector attention retroactively, once later sets establish the format.

For European collectors, the practical play is to secure sealed product at MSRP during the pre-release window (October 24 to November 1) or in launch week. Set TCGRadar alerts now so you catch pre-order listings the moment retailers open them.
