Pokémon hasn't announced an English card count for Delta Reign. Its Japanese predecessor, Storm Emeralda, has 113 cards — a 76-card main set plus 37 secret rares — which gives a strong indication of size, though the English total isn't confirmed.
Not officially confirmed for English
Pokémon hasn't announced a card count for the English Delta Reign release. What we do have is the checklist for its Japanese predecessor.
What the Japanese predecessor tells us
Storm Emeralda, the Japanese set Delta Reign is built from, released July 31, 2026 with 113 cards: a 76-card main set plus 37 secret rares. Bulbapedia notes those cards are expected to carry into Delta Reign, so 113 is a strong indicator of size — but English Mega Evolution sets don't always match their Japanese counterpart card-for-card, so treat it as a guide rather than a confirmed English total.
Check back closer to launch
We'll fill in the confirmed English count, chase cards and a binder layout as Pokémon reveals the set ahead of its November 6, 2026 release.
Pre-release set. Delta Reign isn't out yet — everything here is from official reveals and TCG news as of August 2026, and details can still change before launch. We'll swap in full card data once it releases.
