Storm Emeralda Mega Rayquaza ex officially revealed with split Stadium card

Storm Emeralda Mega Rayquaza ex is finally here in full. Following weeks of trademark leaks and a brief teaser, The Pokemon Company officially unveiled Japan's M6 set on June 28th, 2026, dropping a complete reveal of the set's star card, its unique new mechanic, and confirmed details on the full card slate. July 31st just got a lot more interesting.

Here's everything confirmed so far:

• 76 cards in the main set, plus 35-40 secret rares (roughly 115 total)
• Mega Rayquaza ex with 280 HP and a devastating scaling attack
• Legendary Summit, the world's first split Stadium card
• New Supporters: Zinnia's Trust and MC's Hype
• Talonflame ex as a powerful bench support partner
• English release as Delta Reign on November 6th, 2026

What is Storm Emeralda?

Storm Emeralda is Japan's sixth Mega Evolution set in the current Scarlet and Violet era, releasing on July 31st alongside three MEGA Starter Decks. The name is a direct nod to Pokemon Emerald, where Rayquaza famously lives in the ozone layer above the Sky Pillar. The "a" suffix might also reference Legends: Z-A, where Mega Rayquaza plays a key role in the DLC story.

The set was first trademarked back in June 2025, a full year before this week's official reveal. Fans had preliminary information since February 2026, but complete card translations and set details only landed now. The English equivalent, Delta Reign, references Rayquaza's delta design motif and its signature Ability, Delta Stream. Western collectors will need to wait until November 6th to pull from Delta Reign, a three-month gap after Japan gets Storm Emeralda.

That delay has a clear cause. Storm Emeralda was originally expected to follow the standard two-month Japanese-to-English window, but the special worldwide release of the 30th Celebration set in September claimed that slot and pushed Delta Reign back to November. Frustrating, but at least the wait is finite.

Mega Rayquaza ex: everything you need to know

Mega Rayquaza ex is a Basic Pokemon with 280 HP, which sits right in the expected range for this era's Mega Evolution headliners. What makes it stand out is the combination of its Ability and its attack's scaling formula.

Champion's Roar activates the moment you play Mega Rayquaza ex from your hand to the Bench. You look at the top four cards of your deck, attach any Basic Energy you find there directly to Mega Rayquaza ex, and shuffle the rest to the bottom. Free energy acceleration on entry is genuinely strong, especially for a card that wants both Fire and Lightning energies loaded to hit meaningful damage numbers.

The attack, also called Storm Emeralda, deals 50 damage times the number of Fire and Lightning Energy attached to all your Pokemon in play. Not just on Mega Rayquaza itself. That means a board with multiple energy-loaded Pokemon, including the Talonflame support line, can push this well past 200 damage consistently. Getting to 300 damage is realistic with a full board. The Mega Evolution ex rule applies here: your opponent takes three Prize cards when Mega Rayquaza ex is Knocked Out.

The deck wants energy density above all. Adventuring Lantern, a new Item card, fetches one Basic Fire Energy and one Basic Lightning Energy from your deck simultaneously. Two energy for one Item is a clean enabler. The Mega Rayquaza Cap Pokemon Tool adds another layer: for each of your Pokemon with a Cap attached, you can search your deck for a Basic Energy and attach it to that Pokemon. Stack enough of these and the Storm Emeralda attack caps out fast.

Legendary Summit: the first split Stadium card

This is the genuinely new mechanic in Storm Emeralda, and it's one that long-time players will recognize immediately. Legendary Summit is a Stadium that must be played as two halves, both from your hand at the same time, before it counts as a single Stadium in play. This directly echoes the LEGEND cards from the HeartGold and SoulSilver era, which required two halves to function.

The effect is targeted and meaningful. While Legendary Summit is in play, when a Pokemon is Knocked Out by damage from an opponent's attack, both players' Colorless Pokemon give up one less Prize card. That's a direct benefit for Mega Rayquaza ex, a Colorless Pokemon, reducing your opponent's Prize gain from three to two on a Knock Out. Less free tempo for the opponent every time your headliner gets removed.

The obvious design question is whether Legendary Summit will be the only split card in the set. Nothing else has been confirmed yet. Given that the HeartGold and SoulSilver era used LEGEND cards as a recurring mechanic rather than a one-off, it seems likely that more split cards could appear in future sets or even later in Storm Emeralda's secret rare lineup. We won't know until Japan opens packs in August.

Supporting cast worth knowing

Storm Emeralda reveals several cards beyond the headliner that look like they'll see real play.

Talonflame ex is a Stage 2 with 280 HP and the Excitedive Ability, which lets you bench it directly from your hand if you already have a Colorless Mega Evolution Pokemon in play. Zero setup energy to field it. Its Claw Hunt attack hits 150 damage for two Colorless energy and lets you fetch two cards from your deck, keeping your hand stocked throughout the game. The full Fletchling evolution line is in the set to support this.

Zinnia's Trust is a Supporter that switches your Active Pokemon with a Benched Pokemon and moves one Energy from the previous Active to the new one. It's essentially a free retreat plus energy transfer in a single card slot, which is exactly what energy-hungry Mega Evolution decks have needed since the format began.

MC's Hype draws two cards and draws two more if your opponent has three or fewer Prize cards remaining. A late-game hand refill that triggers precisely when you need it most. Simple card, high ceiling in the right matchups.

The overall package is coherent. Mega Rayquaza ex gets free bench entry with Champion's Roar, Adventuring Lantern feeds its dual-energy requirement, Zinnia's Trust keeps it mobile without wasting energy, and Talonflame ex provides board presence while keeping draws flowing. This is one of the more complete archetypes revealed in a Mega set so far.

MEGA Starter Decks launching the same day

July 31st also brings three MEGA Starter Decks at 1,800 yen each, each built around a featured Pokemon ex. Every Pokemon in these decks is new to the card pool, with seven to nine new cards per deck, totalling roughly 20 to 30 unique cards across the three products.

The three decks feature Eevee ex, Meowscarada ex, and Zoroark ex as their respective headliners. Eevee ex (200 HP) draws three cards with Collect and hits 200 damage with Brave Dash, though the coin-flip tails result deals 30 self-damage. Meowscarada ex (320 HP) carries a spread attack that also hits any Benched Pokemon with existing damage counters, for 120 damage across two targets simultaneously. Zoroark ex (270 HP) scales its attack based on how many Pokemon you have in play.

These decks also introduce some interesting support lines. The Pawmot evolution line in the Eevee deck adds a Lightning energy acceleration Ability from the discard pile, and Arboliva in the Meowscarada deck provides a recurring forced-switch effect on your opponent's side. Useful utility that could find homes in future builds well beyond these starter formats.

What comes after Storm Emeralda?

Japan's TCG calendar for the rest of 2026 is packed. After Storm Emeralda and the MEGA Starter Decks on July 31st, the global 30th Celebration set launches September 16th. October 16th brings nine 30th Celebration Card Sets featuring all 27 Starter Pokemon promos from the "First Partner Collections." November 13th lands a Special Deck Set starring Mega Feraligatr ex, Mega Dragonite ex, and Mega Gengar ex, and then Aura Seeker featuring Mega Lucario Z ex closes out November on the 27th. A rumoured High Class Pack has yet to be officially confirmed.

Storm Emeralda delivers exactly what the community was waiting for. The split Stadium mechanic alone makes this a set worth paying close attention to, regardless of whether Mega Rayquaza ex ends up defining the competitive format. The energy-scaling attack has real ceiling, the Talonflame support line is clean, and Zinnia's Trust solves a recurring pain point for Mega decks. Delta Reign on November 6th will be the full English story, but July 31st is when it begins.
