About the data

Where this list comes from

Card data from TCGdex (tcgdex.dev), an MIT-licensed community database — snapshot September 22, 2026. If anything differs, the card itself is the final word.

Rarity names are TCGdex’s, shown in Title Case (“Double rare” appears as Double Rare).
STS is the abbreviation TCGdex records for this set. It isn't printed on these cards: printed set codes replaced set symbols with Scarlet & Violet in 2023.

tcgdex.dev (opens in a new tab) is a community project, not affiliated with The Pokémon Company.
