Double Blaze (SM10): Japanese Equivalent of Unbroken Bonds (2019)
By Dexhaul Team · October 13, 2026 · 6 min read
Japanese SM10 Double Blaze (March 1, 2019) became English Unbroken Bonds (May 3, 2019), a 63-day gap that let JP collectors open Reshiram & Charizard-GX packs more than two months before EN players. The set mapping is not one-to-one: English Unbroken Bonds (214 cards) combined SM10 Double Blaze with cards from other JP SM10-era sub-releases, resulting in more than double the card count.
The set name itself is the first clue for collectors who know Japanese TCG naming conventions. "Double Blaze" is the name of Reshiram & Charizard-GX's GX attack. English sets rarely signal the star card this directly, so EN buyers who opened Unbroken Bonds packs often did not realize the set's Japanese name pointed straight to its most-wanted card.

Set mapping at a glance
| Set | Code | Released | Cards (main + SR) | MSRP per pack (at launch) |
|---|---|---|---|---|
| Double Blaze (JP) | SM10 | March 1, 2019 | 95 + 19 SR | 165 yen (5 cards) |
| Unbroken Bonds (EN) | SM10 (EN) | May 3, 2019 | 214 + 27 SR | $3.99 USD (10 cards) |
The 63-day release gap is tight by modern standards. EN Unbroken Bonds drew from SM10 Double Blaze as its primary source, then incorporated cards from other JP SM10-era sub-releases to fill its larger 214-card roster.
What's different in each box
| Feature | JP SM10 Double Blaze | EN Unbroken Bonds |
|---|---|---|
| Cards per pack | 5 | 10 |
| Packs per booster box | 30 | 36 |
| Cards per booster box | 150 | 360 |

| Booster box (secondary, Oct 2026) | ~$599.99 USD | ~$2,858.00 USD |
One booster box of SM10 gives you 150 cards across 30 packs. EN Unbroken Bonds gives you 360 cards across 36 packs. The EN box contains more than twice the cards, but at current secondary market prices, the JP box is considerably cheaper per pack.
Key card crosswalk
Reshiram & Charizard-GX is the defining card of the Double Blaze set. Its GX attack is literally named "Double Blaze GX," which is how the entire JP set got its name. EN collectors got this card as 020/214 in Unbroken Bonds; JP collectors pulled it from SM10 packs more than two months earlier. For the full card-number crosswalk across both sets, Serebii's Double Blaze index maps JP numbers to their EN equivalents.
| Card | EN UNB Number | Rarity | JP Source | Observed Price (Oct 2026) |
|---|---|---|---|---|
| Reshiram & Charizard-GX | 020/214 | Ultra Rare | SM10 Double Blaze (star card) | $59–65 USD |
| Marshadow & Machamp-GX | 062/214 | Ultra Rare | SM10 Double Blaze era | Under $10 USD |
| Moltres & Zapdos & Articuno-GX | 066/214 | Ultra Rare | SM10 Double Blaze era | $15–25 USD |
| Gardevoir & Sylveon-GX | 130/214 | Ultra Rare | SM10 Double Blaze era | Under $10 USD |
| Reshiram & Charizard-GX | 217/214 | Full Art Ultra Rare | SM10 Double Blaze (SR alt art) | $40–75 USD |
Prices above are observed at current secondary market listings, not MSRP. Unbroken Bonds was released in 2019 and is a vintage sealed product; singles remain accessible for most TAG TEAM GXs outside of Reshiram & Charizard-GX.
Japanese or English: four things to check
Price per card
A JP SM10 booster box costs roughly $599.99 USD at secondary market prices observed October 2026 (30 packs, 5 cards each = 150 cards). That works out to about $4.00 per card. An EN Unbroken Bonds booster box at the same market runs roughly $2,858.00 USD (36 packs, 10 cards each = 360 cards), or roughly $7.94 per card. JP Double Blaze currently offers the lower per-card cost at secondary prices, even though EN gives you more cards per box.
Play legality
Japanese SM10 cards are not legal in official English-language Pokémon TCG tournament play. If your goal is playing in sanctioned events, you need the EN Unbroken Bonds versions. For home play, sealed collecting, or display, the JP versions are identical mechanically and are often preferred for their more compact artwork (a 5-card pack shows less white space around art).
Language and grading
JP cards are graded on the same PSA/CGC scale as EN cards; Serebii's Unbroken Bonds page lists both versions for cross-reference. Graders treat JP and EN copies as separate card entries in their population reports. The Reshiram & Charizard-GX JP version from SM10 has a smaller print population than its EN counterpart because JP collectors often buy fewer sealed boxes of a set years after release.
Sealed product condition
SM10 Double Blaze booster boxes are sold both "with shrink" (factory-sealed outer wrap intact) and without. Always confirm shrink status in the listing. EN Unbroken Bonds booster boxes and Elite Trainer Boxes at secondary prices command a premium for factory-sealed condition, so check listing photos carefully before buying at either price point.
Double Blaze as a holiday gift
For collectors who already have the EN version, a sealed JP SM10 Double Blaze booster box or individual packs make a genuinely distinct gift. The Japanese art differs from EN in subtle ways (original artwork context before card cropping), and opening JP packs has a different sensory experience because of the smaller 5-card format.
If you are buying for someone who wants the Reshiram & Charizard-GX for their collection, JP individual packs (around £19.99 each) give the recipient that authentic JP experience at a more accessible price than a full box. The SM9 Team Up guide covers the set immediately before Double Blaze in the TAG TEAM GX era. For a broader map of every JP set and its EN equivalent, the Japanese Pokémon sets guide is the reference page.

FAQ
Is Double Blaze the same set as Unbroken Bonds?
SM10 Double Blaze (JP) is the primary source for EN Unbroken Bonds, but they are not identical. EN Unbroken Bonds has 214 cards versus JP SM10's 95, because EN combined Double Blaze with cards from other JP SM10-era sub-releases.
Why is the set called Double Blaze?
The name comes from Reshiram & Charizard-GX's GX attack, "Double Blaze GX." Japanese sets are commonly named after the star card's signature move or mechanic, which is why knowing the JP set name tells you immediately which card the set was built around.
Can I use JP SM10 cards in English tournament play?
No. Japanese cards are not legal in official English-language sanctioned events. They are legal in JP-format events and are a valid choice for home play, sealed collecting, or display.
Which is cheaper: JP Double Blaze or EN Unbroken Bonds?
At current secondary market prices observed October 2026, JP SM10 booster boxes run around $599.99 USD versus EN Unbroken Bonds booster boxes at roughly $2,858.00 USD. JP Double Blaze is significantly cheaper, though it contains fewer total cards per box.
