One Piece Card Game OP-17: The World’s Strongest Warriors Booster Box

Step into the next major chapter of the One Piece Card Game with OP-17: The World’s Strongest Warriors. Released as part of the game’s 4th Anniversary celebration, OP-17 brings powerful new cards, returning fan-favorite Leaders, premium artwork, and new strategies designed to shake up the competitive game.

The set moves the One Piece Card Game toward the era of the Four Emperors and the island of Elbaf, bringing some of the series’ strongest and most memorable characters into the spotlight. Whether you collect One Piece cards, build competitive decks, or simply enjoy opening booster packs, OP-17 offers plenty to chase.

What Makes OP-17 Special?

One of the biggest features of The World’s Strongest Warriors is the return of popular Leaders with completely new cards and effects. These redesigned Leaders give players new ways to build around familiar characters while introducing strategies capable of changing the current One Piece TCG environment.

OP-17 also adds cards designed to strengthen a wide variety of existing decks. That means you do not necessarily need to build an entirely new deck to benefit from the expansion—many of the new cards can be used to upgrade strategies from previous One Piece Card Game sets.

Collectors also have plenty to look forward to. The expansion includes beautifully designed cards, parallel versions, Special Cards, Secret Rares, and a highly collectible Treasure Rare among its premium card lineup.

OP-17 Booster Box Contents

Each sealed One Piece OP-17 Booster Box contains:

• 24 booster packs
• 12 cards per booster pack
• 288 cards total across the box
• Cards randomly selected from the OP-17 expansion
• Opportunities to pull Rare, Super Rare, Secret Rare, Special, Treasure Rare, parallel and alternative-art cards

Individual card pulls are random, and purchasing a booster box does not guarantee any particular card or rarity.
