Doublade from the Pokémon Korean Nihil Zero set (#56) appears as an Unknown rarity card in the Pokémon Trading Card Game. Collectors view it mainly as a set filler rather than a high-demand chase piece, reflected in its current market value of $0.00. Its presence in the Nihil Zero print run gives it contextual interest for completionists building region-specific collections. Grading and sales history are sparse, which keeps resale activity minimal.
