Alter Genesis was the final main expansion of the Sun & Moon era in Japan. Released September 6, 2019, SM12 “オルタージェネシス” closed out the main expansion run with Arceus & Dialga & Palkia-GX at card 65.
This guide covers what’s actually inside a sealed Alter Genesis box, which GX cards make it worth opening, how the box is currently listed on our site, and how it relates to the Japanese-only spin-off pack that followed it a month later. We ship Japanese sealed product out of Tokyo, so the listing prices below reflect what’s currently live on the site.
Alter Genesis (SM12) has a main numbering run through 095, with secret-numbered cards above it, and is built around Arceus & Dialga & Palkia-GX at card 65 — its six numbered GX cards are all Double Rare. A sealed SM12-Alter Genesis Japanese Booster Box is currently listed at ¥63,000 (~$396). The related Japanese-only spin-off, SM12A-Tag All-Stars, is currently listed at ¥207,900 (~$1,308) — a separate high-class pack, not a companion box for the same cards.
Prices below are converted at ¥159/USD (September 2026). Box prices are for sealed product currently listed on our site; no pull-rate figures are quoted anywhere in this guide.
What’s in an Alter Genesis Booster Box
Alter Genesis was released in Japan on September 6, 2019 as the final main expansion of the Sun & Moon era. Its main numbering runs through 095; secret-numbered cards sit above it.
| Item | Value |
|---|---|
| Release date (JP) | September 6, 2019 |
| Main numbering | Through 095; secret-numbered cards sit above it |
| Packs per box | 30 |
| Cards per pack | 5 |
That’s a 30-pack main-expansion structure rather than the 10-pack format used for the separate high-class pack discussed further down.

Chase Cards in Alter Genesis
Alter Genesis carries six numbered GX cards at the Double Rare tier. By number: Volcarona-GX (#13), Oricorio-GX (#35), Flygon-GX (#44), Arceus & Dialga & Palkia-GX (#65), Naganadel & Guzzlord-GX (#66), and Mega Lopunny & Jigglypuff-GX (#73).
Arceus & Dialga & Palkia-GX (65/095)
“ADP” combines three Creation Trio legendaries into a single Tag Team GX at card 65/095. An ADP GX single is not currently listed on our site; sourcing requests for it go through Quick Order.
Naganadel & Guzzlord-GX (66/095)
Sitting right after ADP GX in the number run, this Tag Team GX pairs an Ultra Beast with a Poison-type dragon. As with ADP GX, we don’t currently have a Naganadel & Guzzlord-GX single listed — requests go through Quick Order.

Volcarona-GX (13/095) and Flygon-GX (44/095) are single-Pokemon GX cards drawn from earlier in the number run, while Mega Lopunny & Jigglypuff-GX (73/095) is another Tag Team pairing alongside ADP GX and Naganadel & Guzzlord-GX. Oricorio-GX (35/095) rounds out the six-card GX lineup; no image of that print is confirmed for this guide, but it sits at the same Double Rare tier as the other five.

Regular Box vs Damaged Box vs No Shrink on Our Site
On sets where box condition varies, we list separate Regular, Damaged Box, and No Shrink listings so buyers can choose based on what they’re planning to do with the box — a Regular listing is factory-sealed with an intact shrink wrap, a Damaged Box listing has a marked or dented outer box at a reduced price, and a No Shrink listing is sealed product sold without its original shrink wrap.
For Alter Genesis specifically, the standard Regular SM12-Alter Genesis Japanese Pokemon Booster Box is currently listed at ¥63,000 (~$396). A Damaged Box or No Shrink listing for this particular set is not currently on our site — sourcing requests for either go through Quick Order.
