Known universally as “ADP,” this Tag Team trio defined competitive play in the late Sun & Moon and early Sword & Shield formats. The Rainbow variant commands ¥12,000 ($85) thanks to both its competitive legacy and striking rainbow-foil treatment featuring all three creation legendaries.

Naganadel & Guzzlord GX SA showcases the Ultra Beast duo in a dramatic, otherworldly illustration.

The Special Art treatment elevates what was already a popular competitive card.
Other Notable Cards
Arceus & Dialga & Palkia GX (Regular Art) — ¥2,500 ($18). The standard version of the ADP trio remains accessible and highly playable, offering the same game-defining Altered Creation GX attack at a fraction of the Rainbow variant’s price.
Mega Lopunny & Jigglypuff GX SA — ¥5,000 ($35). A charming Tag Team Special Art featuring the fairy-type duo, popular among collectors for its playful illustration style.
Arceus & Dialga & Palkia GX SR — ¥6,000 ($43). The Super Rare full-art version sits between the regular and Rainbow variants in both price and visual impact.

At a 54% EV ratio, SM12 Alter Genesis follows the standard pattern for Sun & Moon era sealed product — the box commands a collector premium above its aggregate single-card value. The ADP GX Rainbow and both Special Arts provide meaningful upside in individual boxes, while the sealed product itself continues to appreciate as the final main SM expansion.
Alter Genesis Box Price History
Alter Genesis has shown steady appreciation since its 2019 release. Starting at the ¥4,950 MSRP, boxes climbed gradually through the Pokemon TCG boom of 2020-2021 and have continued to gain value as supply decreases. At ~¥14,000 in April 2026, SM12 represents a nearly 3x return from retail — modest compared to headliners like Eevee Heroes, but consistent and reflective of strong collector demand for the final SM main set.

SM12 Alter Genesis was the last main expansion to introduce new Tag Team GX cards before the mechanic was retired.
What is the difference between SM12 Alter Genesis and SM12A Tag All-Stars?
