What Delta Reign is
The short version
Delta Reign is the sixth Mega Evolution expansion and lands on 6 November 2026. It is the English adaptation of Storm Emeralda, the Japanese M6 set that released on 31 July. The gap between the two is unusually long at just over three months, because the 30th Celebration global launch took the September slot that a set like this would normally occupy.
Four Mega Evolution ex cards anchor the set: Mega Rayquaza ex, Mega Golisopod ex, Mega Golurk ex and Mega Malamar ex. Rayquaza is not sharing the spotlight. In Japan it accounts for the two most expensive cards in the set by a factor of seven over the next card down, and there is no reason to expect the English printing to behave differently.
At 113 cards this is a small set, less than half the size of Ascended Heroes. Smaller sets concentrate value rather than spreading it, which is part of why the Rayquaza cards are pulling the numbers they are.
What the Japanese prices tell us
Storm Emeralda (M6) · live market · the leading indicator
English cards do not exist yet, so nobody can quote you an English price. What does exist is the Japanese parent set, trading since the end of July. These are the cards Delta Reign will be built from, and they are the best available read on where the English chase will land.

How to read this
Japanese and English prices are not the same number and never have been. English print runs are larger, the buyer pool is different, and card numbering shifts when secret rares are re-slotted. Treat this table as ranking rather than pricing. It tells you which cards will matter, not what they will cost.
The one thing it says confidently: the gap between Mega Rayquaza ex and everything else is enormous. Card three in this set is worth under a tenth of card one. If you are buying Delta Reign singles, that is where the money goes.
New in this set
Split Legendary Stadiums
The first split Stadium cards in the series
Delta Reign introduces paired Stadium cards that share a single illustration split across two cards, and both halves can be run together in the same deck. Three pairs are confirmed.
Worth watching as a collector rather than a player. Split-art mechanics tend to create demand for complete pairs, which historically prices the set higher than either card would carry alone.
