Delta Reign Pokémon Cards

Delta Reign is part of the Mega Evolution series, which paces the Pokémon TCG releases throughout 2026, and would be one of the last major expansions of the year. The set was revealed as part of the Soaring Mega Rayquaza campaign, which places Mega Rayquaza at the center of official communications.

The full English title is Mega Evolution: Delta Reign, and in Japan the expansion is called Storm Emeralda.

The Delta Reign title likely references the Delta Episode from Pokémon Omega Ruby and Alpha Sapphire, a storyline centered on Rayquaza, rather than the Delta Species mechanic from the third generation of the trading card game. This interpretation remains speculation and not an official confirmation.

Mega Rayquaza ex, the flagship card

The set's trailer highlights Mega Rayquaza ex, presented as the centerpiece card of Delta Reign.

Mega Rayquaza had not held a leading role in the Pokémon TCG since the XY era, making Delta Reign a particularly anticipated return for collectors. No other cards from the expansion have been confirmed at this time.

Complete details on attacks, hit points, and gameplay synergies will be added as they are officially published.

Release date and schedule

Delta Reign follows the standard release schedule for international Pokémon TCG expansions, with two distinct dates:

• Japanese release: July 30, 2026, under the name Storm Emeralda
• International release: November 6, 2026

The international version is expected for autumn 2026.

Available products and formats

Official products for Delta Reign have not yet been announced. This section will be updated once boosters, boxes, and other formats are revealed ahead of the November 6, 2026 release.

Collecting, rarity, and market

Delta Reign is part of the Mega Evolution series, which has seen strong interest from collectors since the launch of earlier expansions in the series. The return of Mega Rayquaza, absent from the spotlight since the XY era, is expected to generate significant attention on the secondary market.

Average prices for each card will be available on this page once the expansion is released. Rarity, condition, and demand remain the main factors influencing a card's market value.

Community and gameplay experience

Like previous Mega Evolution expansions, Delta Reign appeals to both competitive players and collectors. The confirmation of Mega Rayquaza ex suggests decks built around this central card, but other mechanics and synergies will depend on cards yet to be revealed.

Official events and tournaments tied to Delta Reign will be communicated by The Pokémon Company as the release approaches.
