Storm Emeralda (M6) English Equivalent: Delta Reign ME06 (2026)
By Dexhaul Team · October 5, 2026
Japanese Storm Emeralda (M6), released July 31, 2026, is the Japanese source set for English Mega Evolution Delta Reign (ME06), which launches November 6, 2026. The two share Mega Rayquaza ex as the headline pull. The 98-day gap between them is the longest localisation window in the entire Mega Evolution TCG series.
If you bought JP M6 as a stop-gap while waiting for EN, that wait is longer than the M4 or M5 gaps suggested it would be. If you have not yet bought anything, the EN pre-order window is open now.

What is different in the box
The pack structure is the biggest physical difference. JP M6 packs hold 5 cards each, 30 packs per box. EN ME06 packs hold 10 cards each, 36 packs per box.
You open more than twice as many cards from a single EN box.
Card count follows from that math: 150 JP cards vs 360 EN cards per box. Prior ME sets also show that the English print typically includes cards with no JP equivalent, added during localisation.
ME04 (Chaos Rising) had 13 EN-only cards that do not appear in JP M4 at all, and the ME04 import guide covers that split. ME06 may follow the same pattern, but the full EN card list is not yet released; official EN card details will be confirmed at launch.
EN-only formats: what JP buyers cannot get
Three English formats have no JP equivalent at all. The first is the Elite Trainer Box, which includes exclusive accessories and a foil promo card. JP has no bundled ETB product for M6.
The second is the Booster Bundle, an EN retail format offering multiple packs at a set price. JP has no equivalent bundle tier.
The third, and most collector-significant, is the Build & Battle Box. English prerelease events run October 24-27, 2026 at local game stores.
Every sealed Build & Battle Box opened at a prerelease produces a factory-stamped promo card, unique to the prerelease format. There is no JP production of this card and no route to it through JP imports.
Collectors who bought only JP M6 cannot obtain the stamped promo at any price from the Japanese side.
The per-card price gap is smaller than it looks
The JP box floor of $79 versus the EN pre-order floor of $249.95 creates a headline gap of $170.95. That number is misleading.
A JP box contains 150 cards ($79 / 150 = $0.53 per card). An EN box contains 360 cards ($249.95 / 360 = $0.69 per card).
The real difference is $0.16 per card, not $170 per box. The EN box costs more because it contains 2.4 times as many cards, not because the per-card rate is dramatically higher.
This is a consistent pattern across the ME series. The M5 / ME05 (Pitch Black) gap was $0.04 per card, as the Abyss Eye M5 import guide documents. The M4 / ME04 gap was $0.06 per card.
M6 sits wider at $0.16, partly because EN pre-order floors remain higher than street price at launch typically turns out to be. By November 6, EN street prices will likely compress.
The 98-day gap: a reversal in the ME series
The JP-to-EN localisation pace has not been consistent across the ME series. M4 (Ninja Spinner) to ME04 (Chaos Rising) took 70 days.
M5 (Abyss Eye) to ME05 (Pitch Black) took 56 days. That shortening gap suggested English releases were accelerating.
M6 to ME06 reverses that entirely: 98 days. It is the longest JP-to-EN window in the ME series. Collectors who imported M5 and based their expectations on a 56-day repeat faced a 42-day longer wait for the English counterpart.
The gap matters for two groups. Players who want to use cards in Japanese-language sanctioned play can access them now. Players competing in English-language events need to wait for the November 6 EN print, and pre-order demand through October reflects that.
| JP set | JP release | EN set | EN release | Gap (days) |
|---|---|---|---|---|
| Ninja Spinner (M4) | Mar 13, 2026 | Chaos Rising (ME04) | May 22, 2026 | 70 |
| Abyss Eye (M5) | May 22, 2026 | Pitch Black (ME05) | Jul 17, 2026 | 56 |
| Storm Emeralda (M6) | Jul 31, 2026 | Delta Reign (ME06) | Nov 6, 2026 | 98 |
Japanese or English How to choose
Price per pack
JP single packs are sold loose from several sellers at around $3 each (5 cards). EN single packs will be available at launch as part of the three-pack blister format, typically at around $6 per pack (10 cards). Per pack, EN delivers twice the cards for roughly twice the price: the per-card rate is comparable once pack size is factored in.
Play legality
JP M6 cards are currently legal in Japanese-language sanctioned play. English Delta Reign ME06 cards become legal in English-language play on November 6, 2026. If you are playing competitively in English events between now and November 5, JP cards are not usable in those tournaments unless the tournament is explicitly Japanese-language sanctioned.
Language and reading ease
JP cards are printed in Japanese. For display and collection purposes this makes no practical difference.
For deckbuilding and tournament play, English cards are required at English-language events. Bilingual collectors often hold both versions of chase cards.
Grading
PSA, CGC, and BGS each accept both JP and EN Pokémon cards for grading. JP M6 cards are available to submit now.
EN ME06 cards can be submitted from November 6 onwards. For high-value pulls like the Mega Rayquaza ex SIR, grading either language version is currently accepted without a premium penalty for the JP language variant.

Frequently asked questions
Is Storm Emeralda the same set as Delta Reign?
Storm Emeralda (M6) is the Japanese source set. Delta Reign (ME06) is its English counterpart, releasing November 6, 2026. They share most of the same cards, but EN prints typically add cards that have no JP equivalent, and several English product formats (ETB, Booster Bundle, Build & Battle Box) do not exist in the JP release.
How many cards are in Storm Emeralda M6 vs Delta Reign ME06?
A JP M6 booster box contains 150 cards (30 packs, 5 cards each). An EN ME06 booster box contains 360 cards (36 packs, 10 cards each). The EN card list has not yet been published; total card count for ME06 will be confirmed closer to the November 6 launch.
Is the stamped prerelease promo in Delta Reign available from JP M6?
No. The factory-stamped promo from English Build & Battle Box prerelease events (October 24-27, 2026) is exclusive to those events. It does not appear in JP M6 and cannot be obtained through Japanese imports.
How long until Delta Reign ME06 releases after Storm Emeralda M6?
Storm Emeralda released July 31, 2026. Delta Reign releases November 6, 2026: a 98-day gap. This is longer than the M4-to-ME04 gap (70 days) and the M5-to-ME05 gap (56 days), making it the widest JP-to-EN window in the ME series.
Should I buy JP M6 now or wait for EN ME06?
Buy JP M6 if you need the cards before November 6 for Japanese-language sanctioned play, or if you prefer Japanese-print collector copies at a lower per-card rate. Wait for EN ME06 if you compete in English-language events, want the EN-exclusive ETB or prerelease promo, or prefer English-language cards.
