Storm Emeralda vs Delta Reign: Japanese Now or English in November?

Since 31 July 2026 you have been able to buy the Japanese cards that Delta Reign will draw from: the set is M6: Storm Emeralda, and Mega Rayquaza ex is in it. The English expansion follows on 6 November 2026. (sources: Delta Reign expansion page) The question collectors are actually asking is which one to buy. The answer depends on what you want the card for, because they are two different cards.

Why they are different products

• Language and set. A Storm Emeralda card is printed in Japanese with the Japanese set's symbol and code; the Delta Reign card will be printed in English with its own. Our card matching treats them as separate cards, and each gets its own page and its own market reference.
• Numbering. The Japanese set has 76 main-set cards (113 with the secret rares above the printed total, per collector sites). The English set is “over 135 cards” by the official wording, so the numbering will not line up, and a Japanese number is not a prediction of an English one.
• Contents. English sets in the Mega Evolution Series have not been one-to-one copies of their Japanese sources. Some Japanese cards may not appear in English; some English cards may come from elsewhere. Nobody outside The Pokemon Company knows the mapping yet.
• Market. The two cards trade in different pools with different references. A Japanese price says nothing about what the English card will trade at, in either direction.

Buy the Japanese card now if…

• You want the artwork, and language does not matter to you.
• You collect Japanese cards already, or want the set as it was first printed.
• You are happy to price it as a Japanese card — against Japanese solds, not against whatever the English card later does.

Wait for the English card if…

• You collect English sets, want the English set symbol and number, or want the card for Standard play.
• You plan to grade it: a Japanese and an English copy are graded and sold as different cards.
• You want a market reference before you pay. The English card will have none until it is listed and priced; the Japanese card has one now.

Reading a listing today

• “Delta Reign” in a title over a Japanese card is the common mix-up. Check the language and set symbol in the photos; our set-and-number guide shows where they are printed.
• “Leaked Delta Reign card” describes a Japanese card that has been on sale since July. The photographs that circulated on 28 July 2026, three days before the Japanese release, were of Storm Emeralda cards that then released. There is nothing secret about them now.
• “English” listed before 6 November is a preorder of a card that does not yet exist, or a mislabelled Japanese card. Read preorders and prerelease before paying for either.
• A Japanese card's reference can be checked with the price checker where we hold the printing; if we do not, the page says so rather than showing a figure from the wrong set.

What we will not do

We will not show a Japanese reference on an English card's page, or the reverse, and we will not claim a saving for either until a reference for that exact printing and condition exists. That is the same rule that applied to 30th Celebration before its release day. The official facts about the English set are collected in Delta Reign: what is official so far.
