Price a Demon Slayer card as the UNION ARENA card that it is
A Demon Slayer single is a UNION ARENA card, so match that printing on CardZ Marketcap before you decide whether a price makes sense.
Key points
- The live product is the UNION ARENA Demon Slayer set.
- An asking price is not a completed sale.
- Demon Slayer cards do not share Pokémon collector numbers.
Price lookup
Ask is not sold. Match the print on CardZ Marketcap, then judge the number in front of you. Since there is no standalone Demon Slayer game, the UNION ARENA set code is the only thing that identifies a card properly.
Wider coverage sits on the Demon Slayer cards page (Cantonese) and the UNION ARENA section (Cantonese).
FAQ
Why does the UNION ARENA set code matter?
Because Demon Slayer is a licence rather than a game line. The set and number are what identify the card, and a character name shared across releases is not enough.
Is a listing price a market price?
No. Ask is not sold. Match the printing first, then weigh the asking price against what you find.
Can I look one up by Pokémon collector number?
No. Demon Slayer cards do not share Pokémon collector numbers. Use the UNION ARENA set and number on the card.
Next steps
Match your card on CardZ Marketcap. If you are opening rather than buying singles, start a pool on Cardz.game and price what you keep.
