Delta Reign, the Mega Rayquaza Set Coming to the Pokémon TCG
Delta Reign is the new Pokémon TCG expansion revealed as part of the Soaring Mega Rayquaza campaign. Its full title is Mega Evolution: Delta Reign (Storm Emeralda in Japan), and it puts Mega Rayquaza in the spotlight. Here is its release date and what is known so far.
Mega Evolution: Delta Reign, the physical set
Delta Reign is a physical card expansion. It belongs to the Mega Evolution series that has been pacing Pokémon TCG releases in 2026, and would be one of the final major expansions of the year. No further details on the set have been confirmed yet.
Delta Reign release date
The expansion will launch first in Japan on July 30, 2026, then internationally on November 6, 2026. The international version is the one relevant to English-speaking players, arriving in the autumn.
Mega Rayquaza ex, the featured card
The trailer highlights a Mega Rayquaza ex card. No other cards have been confirmed for now. Mega Rayquaza had not held a leading role in the Pokémon TCG since the XY era, which makes Delta Reign a long-awaited return for collectors.
Why the name Delta Reign?
The English title Delta Reign differs from the Japanese name Storm Emeralda. It most likely references the Delta Episode from Pokémon Omega Ruby and Alpha Sapphire, a storyline centred on Rayquaza, rather than the Delta Species (δ) mechanic from the third generation of the card game. This reading remains an interpretation, not an official confirmation.
