Korean and Japanese cards have identical names and content, just different languages.

The Korean Jet Black Spirit deck, which falls under the Sword and Shield world series, contains 5 random cards.

It was released in Japan on April 23, 2021 and, in addition to 25 new cards, brought a different design
– a new illustrator has started creating cards.

Players often collect cards from the Jet Black Spirit set along with cards from the S6H Silver Lance set (which also contains 25 new cards in total). As always, you have a chance to find Trainer's cards, Energies, or one of the Rare cards.
