Storm Emeralda Reveals Forces of Nature Combo Cards

Storm Emeralda's newest reveal wave, posted July 13, 2026, introduced Tornadus, Thundurus, Landorus, and Enamorus, each carrying a shared "Incarnate Union" ability that only turns on when all four are in play at once. It is the second brand-new multi-card mechanic PokeBeach and Bulbagarden have documented for the set in two weeks, after Legendary Trench joined Legendary Summit as a split Stadium that needs two physical cards to function as one. Storm Emeralda releases in Japan on July 31, 2026, with an English version called Delta Reign confirmed for November 6.

What is the Incarnate Union ability and how does it work?

Incarnate Union is a shared ability printed on all four Forces of Nature cards: if you have Tornadus, Thundurus, Landorus, and Enamorus in play at the same time, that Pokémon ignores all Colorless Energy in the cost of its attacks. It does not add damage or draw extra cards on its own. It is a cost-reduction bonus that only fires once your bench and Active Spot are holding the full quartet, which is a real commitment in a format where bench space is scarce and every one of these four cards is a basic Pokémon rather than an Item or Supporter you can just play and discard.

What are the four Forces of Nature cards' stats and attacks?

Each Force of Nature is a 110-130 HP basic with one attack built around a different type, so the set is asking you to run four separate energy types just to field the combo before Incarnate Union even kicks in.

Card	Number	Type	HP	Attack	Effect
Tornadus	059/076	Colorless	110	Corkscrew Dive (70)	Draw until you have 6 cards in hand
Thundurus	025/076	Lightning	120	Thunder Edge (90)	Ignores effects on the Defending Pokémon for this attack's damage
Landorus	040/076	Fighting	130	Gaia Crush (110)	Discards the Stadium in play
Enamorus	034/076	Psychic	120	Rising Heart (100+)	+100 more damage if the Defending Pokémon is a Pokémon ex

Is the four-card Incarnate Union combo actually competitively good, or just a novelty?

It reads as a fun budget build rather than a serious tournament engine, and the card design backs that up: all four Forces of Nature are Uncommon, the rarity tier the set uses for cards it does not expect to be chased. Cost reduction alone rarely wins games on its own; the attacks that benefit are already playable without the combo, and assembling four different basic Pokémon of four different types onto one bench, ahead of your two Mega ex attackers, is a lot to ask when standard decks only get six total Pokémon in play. The more realistic use case is a theme-deck-style build for players who want to run all four Forces of Nature together for the flavor of it, not a deck that is trying to beat Mega Rayquaza ex at a Regional.

How does this connect to the Legendary Trench split Stadiums revealed the same week?

Legendary Trench and Legendary Summit are both two-card Stadiums: you cannot play either half alone, and both halves have to come down together to function as a single Stadium in play. Legendary Trench, revealed alongside Mega Golisopod ex and Wishiwashi ex, doubles the amount of damage healed whenever either player heals a Pokémon. Legendary Summit, from the set's first reveal wave, instead reduces the Prize cards a player gives up whenever a Colorless-type Pokémon of theirs is knocked out. Put next to Incarnate Union, a pattern shows up across Storm Emeralda's new mechanics: instead of one powerful card doing everything, the set keeps asking you to hold multiple specific cards together before an effect unlocks. That is a deliberate design choice, and it is the clearest fingerprint of this expansion so far.

Mega Golisopod ex (340 HP, Grass) hits for up to 220 with Finishing Blow if the opponent's Active already has damage counters on it, and its second attack, Quatro Hold, deals 160 while locking the Defending Pokémon out of retreating on the following turn. Wishiwashi ex (260 HP, Water) carries the Oceanic Gain ability, healing 50 damage from itself once per turn while in the Active Spot, functionally a built-in Legendary Trench for a single Pokémon.

When does Storm Emeralda release, and what will it cost to open?

Storm Emeralda releases in Japan on July 31, 2026, and the same cards arrive in English inside Delta Reign on November 6, 2026, four months later. US import retailers already have Japanese booster boxes up for preorder: Toywiz lists the 30-pack box at $239.99 shipping in August, and Fujicardshop lists it at ¥30,000. Neither Tornadus, Thundurus, Landorus, nor Enamorus is a headline chase card, so unlike Mega Rayquaza ex, whose day-one and post-launch pricing is tracked in Valusaur's Storm Emeralda price outlook, the Forces of Nature quartet should stay cheap on both sides of the Pacific once singles start listing. That pattern already played out with the last Mega Evolution set's Uncommons, and it is worth checking against the Japanese vs English price gap once Delta Reign singles list in November, since that gap has run roughly two-thirds on chase cards but tends to shrink or disappear on lower rarities. If you are picking up the Japanese boxes now and want to watch how these specific cards price out on TCGplayer and Cardmarket as more reveals land, scanning them into Valusaur keeps both currencies and both marketplaces in one portfolio instead of five open tabs.

Storm Emeralda is the Japanese-numbered M6 set in the Mega Evolution TCG era; for how it lines up against the five sets already out in English, the Mega Evolution set-by-set guide has the full order and signature Mega ex for each.

FAQ

What is Delta Reign? Delta Reign is the confirmed English-language release of Storm Emeralda's cards, arriving November 6, 2026, about fourteen weeks after the July 31 Japanese release.

Are the Forces of Nature cards expensive? No. Tornadus, Thundurus, Landorus, and Enamorus are all printed at Uncommon rarity, the tier the set reserves for cards it is not positioning as chase pulls, unlike the Mega Rayquaza ex and Mega Golisopod ex Pokémon ex cards in the same set.

Can Incarnate Union work with only two or three of the four Forces of Nature in play? No. The ability's text requires all four named Pokémon, Tornadus, Thundurus, Landorus, and Enamorus, to be in play simultaneously before the Colorless Energy cost reduction applies to any of them.

What is a split Stadium, and why does Storm Emeralda have two of them? A split Stadium is printed across two physical cards that must be played together to function as one Stadium in play. Storm Emeralda has introduced two: Legendary Summit, which reduces Prizes given up on Colorless knockouts, and Legendary Trench, which doubles healing for both players.

When can I actually buy singles instead of preordering boxes? Japanese singles should start listing on TCGplayer and Cardmarket around the July 31 release date, with English Delta Reign singles following once that set releases on November 6.
