Start Demon Slayer cards by choosing a UNION ARENA set first
You are buying into UNION ARENA rather than a Demon Slayer game, so settle the set number and language version first, then choose between a starter deck and boosters.
Key points
- The live product is the UNION ARENA Demon Slayer set.
- Confirm the set number and language version before buying.
- A starter deck plays out of the box; boosters chase singles.
Starter
Match number and language first. Then pick a starter deck or a booster. A deck gets you playing straight away, and boosters are the route once a particular card is the reason for the purchase.
Everything you learn here carries across UNION ARENA, since Demon Slayer is one licence within that line. Wider coverage sits on the Demon Slayer cards page (Cantonese) and the UNION ARENA section (Cantonese).
FAQ
Is Demon Slayer its own trading card game?
No. The live product is the UNION ARENA Demon Slayer set, so a first purchase is a UNION ARENA purchase with Demon Slayer artwork on it.
Starter deck or boosters first?
Settle the set number and language version first. A starter deck is then the simpler entry, and boosters make sense when you already know the card you want.
Do Demon Slayer cards share Pokémon collector numbers?
No. They do not. Use the UNION ARENA set and number printed on the card rather than a Pokémon-style lookup.
