The new Chinese-exclusive Pokémon set CSv5c, officially titled Fiery Black Crystal (also referred to as Black Crystal Blaze), includes two confirmed Chinese-exclusive cards as of the latest reveals:

1. Larry (Special Art Rare - SAR) – A reprint from Raging Surf (SV3a), but with brand-new exclusive artwork only available in the Simplified Chinese version.

2. Defiance Band (Ultra Rare - UR) – Originally from Scarlet ex (SV1S), this version features exclusive Simplified Chinese illustration and is one of the few cards in the set not directly translated from Japanese sets.

These exclusives are part of a broader trend where The Pokémon Company is creating illustration-exclusive variants for the Chinese market to drive local interest and collector appeal.

The rest of the set primarily consists of Simplified Chinese translations of cards from:

- Ruler of the Black Flame (SV3)

- Raging Surf (SV3a)

- Ancient Roar (SV4K)

- Future Flash (SV4M)

- Shiny Treasure ex (SV4a)

So while most of the set is localized reprints, the SAR Larry and UR Defiance Band are the standout Chinese exclusives in CSv5c.
