What makes OP-17 special?

The World’s Strongest Warriors [OP-17] was created as a 4th Anniversary booster for the ONE PIECE Card Game.

Rather than focusing on only one group of characters, the set combines the Elbaf storyline with some of the strongest pirates in ONE PIECE history.

The Four Emperors serve as a major Leader theme, while their crews receive additional support throughout the card pool.

OP-17 also introduces Rocks D. Xebec to the ONE PIECE Card Game for the first time, adding one of the series’ most historically important pirates to the game.
