Storm Emeralda (set code M6) came out in Japan on Friday 31 July 2026, and the main set is already fully revealed: 76 cards, with Mega Rayquaza ex on the cover and an idea the game has not used since the LEGEND era, Stadiums printed across two separate cards that you have to play together.
This article is the complete list of the main set alone, card by card, with large images: tap any card to start tracking its value on DarkDex. If you are after prices, the ranking is in its own article: the most expensive Storm Emeralda cards.
In short. Storm Emeralda (M6) came out on 31 July 2026 in Japan, 7 August in Taiwan and Hong Kong. The main set is 76 cards: 8 ex (four of them Mega ex), 7 Holo Rares, 21 uncommons and 40 commons. The special rarities run from number 077 to 113 and live in the chase cards article. Prices as of 11 August 2026.
When does Storm Emeralda come out
In Japan on Friday 31 July 2026. Taiwan and Hong Kong follow on 7 August. It is the sixth set of the Mega Evolution era, and its official code is M6.
These cards do not reach Europe on 31 July. Japanese sets come first and are then reshuffled into Western releases a few months later, often under a different name: it happened days ago with Abyss Eye, which arrived in the West as Pitch Black. So if you are looking for Storm Emeralda in English, for now only the Japanese edition exists.
The four Storm Emeralda Mega ex
Mega Rayquaza ex (#058) is the mascot and it gives the set its name: "Storm Emeralda" is the name of its attack, which does 50 damage for each Fire and Lightning Energy attached to all of your Pokémon. It is Colorless, it has 280 HP, and its Ruler's Roar Ability lets you look at the top four cards of your deck and attach a Basic Energy to it when you put it on your bench from hand.
Mega Golurk ex (#033) is the wall: 350 HP, the highest in the set, and Goliath Punch for 300 damage on just two Psychic Energy. The bill comes with its Power Limiter Ability, which stops it from attacking unless you have ten or more cards in hand, and with the 30 damage it puts on itself every swing.
Mega Golisopod ex (#009) is Grass, 340 HP: Finishing Blow starts at 60 damage but hits for 220 if the opponent's Active Pokémon already has damage counters on it. Mega Malamar ex (#048) is Darkness, 320 HP, and Psychic Marionettes does 70 damage for each of your opponent's Benched Pokémon: the wider they go, the more it hurts.
One rule covers all four: when a Mega Evolution Pokémon ex is Knocked Out, your opponent takes three Prize cards instead of two. That HP and that damage are not free.

The other four ex
- Talonflame ex (#062), Colorless, 280 HP: its Elated Dive Ability puts it straight onto your bench from hand if you have a Colorless Mega Pokémon ex in play. That means Mega Rayquaza ex: this card is written to travel with it.
- Raikou ex (#024), Lightning, 200 HP: Gather Lightning can be used on your first turn if you go first, and pulls a Lightning Energy out of the deck onto it.
- Wishiwashi ex (#021), Water, 260 HP: Oceanic Gain heals 50 damage per turn while it is Active, and Hydro Gain does 220.
- Heat Rotom ex (#015), Fire, 190 HP: Reheat does 30 damage for each Basic Fire Energy in your discard pile, then shuffles them back into the deck.
The Stadiums you play in halves
This is the real structural novelty of the set. Each of the three "Legendary" Stadium cards is printed across two different card numbers: the artwork continues from one half into the other, and the text says you must play both halves at the same time from your hand for them to count as a single Stadium. Anyone with a few years of play behind them will recognise the LEGEND cards from HeartGold & SoulSilver.
What they do:
- Legendary Ocean Trench (#071 + #072): whenever any Pokémon is healed, the healing is doubled. On top of Wishiwashi ex that turns into 100 HP a turn.
- Legendary Summit (#073 + #074): whenever a Colorless Pokémon is Knocked Out by an opponent's attack, the opponent takes one fewer Prize card. On Mega Rayquaza ex, which is Colorless, that means three Prizes become two.
- Legendary Lava Lake (#075 + #076): Evolution Pokémon in play, yours and your opponent's, have no Abilities.
For collectors there is a practical consequence: the main set does not close on 76 different cards, it closes on 76 numbers, and three of those entries are pairs worth keeping together.
The seven Holo Rares
Seven cards, and the Hoenn theme is easy to spot: Groudon (#039) and Giratina (#031) are the headline names, but Altaria, Kommo-o, Nidoqueen, Arcanine and Cacturne all get a slot. Kyogre is in the set too (#018), but as a common, not a Holo Rare.
The Forces of Nature quartet
Tornadus (#059), Thundurus (#025), Landorus (#040) and Enamorus (#034) share the same Ability, Incarnate Union: with all four in play, the Colorless Energy in their attack costs is ignored. Four uncommons, so pocket change on the shelf, but a clear job to do in a deck.
The rest of the Trainers digs deep into Hoenn: Zinnia's Trust (#069), Tate & Liza's Training (#070), Aarune (#068) and the Mega Rayquaza cap (#066), already the most charming card in the set.
The best cards in Storm Emeralda
If "best" means the card the set is built on, it is Mega Rayquaza ex (#058): 280 HP, Colorless so it fits anywhere, and the attack that gives the expansion its name. Everything else orbits it, from Talonflame ex to the Legendary Summit.
If instead you mean the cards worth chasing when you open packs, the sensible order before release is this:
- Mega Rayquaza ex (#058), the cover card, in its full art versions
- Mega Golurk ex (#033), 350 HP, the biggest Mega in the set
- Mega Malamar ex (#048) and Mega Golisopod ex (#009), the other two Megas
- The three paired Stadiums (#071-#076), which being printed across two cards have a demand of their own among people who want the whole illustration
This is not a price ranking, because prices do not exist yet: it is what the set holds and where demand will land. The real ranking arrives once listings go live.
The Storm Emeralda chase cards: SR, AR and SAR
Everything above number 076: the SR, AR, SAR and the Gold, which in recent Japanese sets soak up most of the money in a box. Around forty cards, and 36 of them are already uncovered with a number and an image.
They are not here because they deserve a page of their own: the Storm Emeralda chase cards, one by one, split by rarity, with the three Mega Rayquaza ex versions on top.
How much are Storm Emeralda cards worth
Not much, and that is normal: in a Japanese set almost all of the value sits above number 076. Out of the 76 main set cards only one reaches 5 euro, the normal print of Mega Rayquaza ex #058. Everything else sits below, with most commons and uncommons at a few cents.
The full ranking for the set, chase cards included, is in the most expensive Storm Emeralda cards: the jump is easy to see there, because the same Mega Rayquaza ex goes from 5.00 € as a base print to 864.00 € as the Gold #113.
Prices on a set released days ago swing hard: in the first weeks stock, hype and day-one demand weigh more than they will six months from now. The numbers become trustworthy later, once the mass box opening dries up. The cards are already in the DarkDex catalogue, in any language and condition, with price history card by card.
Careful. The prices quoted here are a snapshot from 11 August 2026, not a fixed list. On a freshly released set they move week by week.
How much is Mega Rayquaza ex from Storm Emeralda worth
It depends which one, and that is the part that catches everybody out. Mega Rayquaza ex exists in four prints inside this one set, at wildly different prices: the #058 base print at 5.00 €, the Full Art #095 at 48.00 €, the Special Art Rare #110 at 430.80 € and the Gold #113 at 864.00 €.
Nearly one hundred and seventy-three times between the first and the last, for the same card in the same set. That is why the collector number matters more than the Pokémon name, and every print is broken down in the most expensive cards ranking.
So watch what you are actually looking at when you check a price: the Pokémon does not set the value, the print does. Collector number, rarity and finish swing the price twentyfold under the same name, which is why adding up a collection by eye never works. If you want the number the moment it exists, the DarkDex price engine keeps every single variant separate and shows the history from the first day of trading.
Storm Emeralda FAQ
How many cards are in Storm Emeralda?
The main set is 76 cards (001 to 076). On top of those come the 37 special rarities from number 077 to 113, for a total of 113 numbers.
What is the best card in the set?
For play it depends on the deck, but the flagship is Mega Rayquaza ex (#058): it gives the set its name through its attack, and the rest is built around it, Talonflame ex and Legendary Summit included. For value its full art versions have the last word: the Gold #113 is worth 864.00 €, that is nearly 173 times the base print.
Is Storm Emeralda coming out in English?
Not under this name. The same cards come back West inside Delta Reign, the matching Mega Evolution expansion, due on 6 November 2026. It is the same mechanism that turned Abyss Eye into Pitch Black: same cover Pokémon, Mega Rayquaza ex, different name and a few months of delay. If you are waiting for the English cards, the date to mark is November, not 31 July.
What are the Stadiums printed across two cards?
Three Stadiums (#071 + #072, #073 + #074, #075 + #076) split into two halves: you play them together from your hand and they count as a single Stadium, with the two illustrations joining into one. It is the same idea as the LEGEND cards from HeartGold & SoulSilver.
Is a Storm Emeralda booster box worth buying?
Right now that cannot be answered with numbers, because neither pack prices nor card prices exist. The rule that always holds: the value of a box sits in a handful of cards at the top, so compare the box price against those, not against the set as a whole.
How to keep an eye on them from day one
On DarkDex you can add your Storm Emeralda cards to your collection right now, before release: the value switches on by itself as soon as listings appear, with price history and your portfolio total always in view. It is how you watch a set move from day one instead of reconstructing it afterwards.
