Mega Rayquaza SIR Leaks From Delta Reign

⚠️ Heads up: This article is based on leaked or unofficial information. Details may change before any official announcement.

🆕 Update, July 29: Three more cards have surfaced from the same batch. A gold Mega Rayquaza ex, a Special Illustration Rare Mega Golurk ex, and a Special Illustration Rare Mega Golisopod ex are covered in the new sections below.

A Mega Rayquaza ex Special Illustration Rare has reportedly leaked from Delta Reign, and it’s not alone. Photos circulating online now show 14 cards claimed to be from the set: five SIRs, a gold Mega Rayquaza ex, and eight Illustration Rares.

Every card in the batch is a Japanese print from Storm Emerald, the set arriving in English as Delta Reign this November. That means they carry Japan’s rarity codes rather than the English ones: AR (Art Rare) is what English calls an Illustration Rare, SAR (Special Art Rare) is a Special Illustration Rare, and MUR is the gold tier that English sets have printed as gold Hyper Rares.

The usual caveat applies. None of these specific prints have been officially revealed, so treat everything below as unconfirmed until The Pokémon Company shows the real thing. That said, the timing lines up with the wave of early material we’ve been seeing, including the Groudon and Growlithe Illustration Rares that surfaced yesterday from the same set.

There’s a simple reason the photos are piling up right now. Storm Emerald releases in Japan on July 31, so copies are already moving ahead of the street date, and every one of these cards should be settled one way or the other within days.

The Mega Rayquaza SIR

Mega Rayquaza ex headlining Delta Reign is old news at this point. That was part of the official English set confirmation back in June, alongside the November 6, 2026 release date and the return of Dragon-types.

What’s new here is the SIR version, shown at the top of this article. A Special Illustration Rare of the set’s flagship Pokémon is almost always the top chase card of an expansion, and if these images are accurate, Delta Reign’s is now out in the open more than three months before release.

The card itself is readable in the photo. It sits at 280 HP, carries a Mega Evolution ex rule box, and has an Ability alongside an attack named ストームエメラルダ, named after the Japanese set itself. That attack does 50 damage times a counter and costs Fire, Lightning, and Colorless Energy, the mixed-Energy pattern Rayquaza cards have leaned on for years. The art shows Rayquaza coiled through a storm of gold and green light, and the whole card is textured edge to edge in the way SIRs have been since the tier was introduced.

The Gold Mega Rayquaza ex

The same Mega Rayquaza ex also turned up as a gold card, numbered 111/076 MUR. Gold prints sit at the very top of a Japanese set’s numbering, and they’re usually the hardest single card in the set to pull.

This photo is the clearest look yet at what the card actually does, because gold prints are legible in a way heavily textured SIRs are not. Here’s what it does:

• 280 HP, a Basic Pokémon, with the Mega Evolution ex rule box (your opponent takes three Prize cards when it’s knocked out)
• Ability: はしゃのほうこう, “Roar of the Ruler.” Once during your turn, when you play this card from your hand onto your Bench, look at the top four cards of your deck, attach one basic Energy you find there to this Pokémon, then shuffle the rest and put them on the bottom of your deck.
• Attack: ストームエメラルダ (Storm Emeralda) for Fire, Lightning, and Colorless Energy. It does 50 damage for every Fire and Lightning Energy attached to all of your Pokémon, not just this one.
• Weakness Lightning ×2, Resistance Fighting -30, Retreat cost 2

That combination is the interesting part. The Ability sets up its own Energy the moment it hits the Bench, and the attack counts Energy across your whole board, so the card rewards spreading Fire and Lightning around rather than loading everything onto the attacker. Four Energy in play is 200 damage, six is 300.

Mega Golurk ex and Mega Golisopod ex SIRs

Rayquaza is not the only Mega Evolution in the set. Two more turned up in the same batch, both in the full-art SIR treatment.

Worth being precise about what’s new here. Both Pokémon already have confirmed main-set cards in Storm Emerald, revealed back on July 23. What leaked is the SIR version of each, which is a separate, much rarer print of the same card. Their Mega forms come from the Mega Dimension content in Pokémon Legends: Z-A, which is where this whole wave of Mega Evolution ex cards is drawing from.

Mega Golurk ex is Psychic-type with 350 HP, the highest in the batch. Its Ability, きどうせいげん (“Mobility Restriction”), says it can’t attack unless you have 10 or more cards in your hand. In exchange, ゴライアスパンチ (Goliath Punch) hits for 300 damage off just two Psychic Energy, with 30 damage back to itself. That is an enormous number for that little Energy, and the hand-size requirement is the whole price of admission. Building a deck that reliably sits at 10 or more cards in hand is not trivial. Retreat cost is 3.

Mega Golisopod ex is Grass-type with 340 HP. とどめをさす (Finishing Blow) costs a single Grass Energy for 60 damage, plus 160 more if the opponent’s Active Pokémon already has damage counters on it. クワトロホールド (Quatro Hold) costs three Colorless for 160 and stops the Defending Pokémon retreating on the next turn. One Energy for a potential 220 is the kind of number that gets a card looked at seriously.

The stats on both photos match the main-set cards that were already revealed, which is a decent sign that these images are what they claim to be. The Golurk photo shows a clear 109/076 SAR. The Golisopod photo is too small to read a number.

Two More SIRs: Raikou ex and Zinnia’s Trust

The leak also includes two other Special Illustration Rares.

The Raikou is a Raikou ex at 200 HP, not a plain Raikou, with the art putting it mid-stride through a dark forest as lightning tears past. An ex SIR that isn’t tied to the set’s headliner usually ends up the second most wanted card in a set, so this one is worth watching.

Zinnia’s Trust is a Supporter, known in Japanese as ヒガナの信頼. Zinnia is a fitting inclusion. She’s the Draconid lore character tied directly to Rayquaza in Omega Ruby and Alpha Sapphire, so a Zinnia Trainer card in a Rayquaza-led Dragon set makes thematic sense. Trainer SIRs have been consistent chase cards in recent sets, and one attached to a fan-favourite character usually holds attention long after release.

Eight Illustration Rares

The remaining cards in the leaked batch are all Illustration Rares, and the first one is the most interesting.

Kyogre stands out immediately. With the Groudon IR leaking just yesterday, the two Hoenn legendaries appearing as Illustration Rares in the same set points to a deliberate weather-trio theme built around Rayquaza, which is exactly what you’d hope for from a set with this headliner. The art has Kyogre breaching through heavy swells with the sky breaking open behind it.

The other seven cover a wide spread of Pokémon and art styles.

Magmortar and Electivire pair naturally, and both photos show enough of the card face to read the numbering. Electivire is 081/076 AR, which tells us the Japanese set has a 76-card main run with the Art Rares stacked on top of it. Magmortar and Pincurchin sit in the same stretch, so this looks like a normal-sized AR tier rather than an unusually deep one.

The smaller Pokémon are where the art gets interesting. Kecleon is the standout, buried inside a kaleidoscope of colour and pattern so busy that finding the Pokémon is most of the point, which is about as on-theme as a Kecleon card can get. Azurill bounces through a wildflower meadow, and Inkay drifts inside a violet underwater vortex. These low-key IRs are often the sleeper favourites once people see the art in hand.

What This Tells Us About Delta Reign

Between yesterday’s Groudon and Growlithe leak and this batch, we’ve now seen a meaningful chunk of Storm Emerald’s special-rarity lineup before any official card reveals for the English set. The Hoenn weather trio angle, a lore-relevant Trainer SIR, a second ex SIR in Raikou, three Mega Evolution ex SIRs, and a gold Mega Rayquaza ex on top of all of it suggest a set built with collectors squarely in mind.

The secret-rare tier is also running deeper than the main set would imply. A 76-card base with Art Rares starting around 078 and a gold card at 111 means at least 35 cards sit above the main run, so the odds of pulling any one specific chase card are thin. Plan accordingly.

Worth keeping in mind for the English release: Japanese sets are routinely reshuffled when they come over, so the numbering above will not carry across, and it’s possible not every card here lands in Delta Reign exactly as shown.

Delta Reign lands November 6, 2026. If the Mega Rayquaza SIR is the card you’re already planning to chase, keep an eye on upcoming Pokémon TCG singles rather than gambling your whole budget on packs.
