ONE PIECE OP-12 Booster Box – Legacy of the Master

Discover the bonds between legendary mentors and their students with the ONE PIECE OP-12 Booster Box, featuring the English edition of Legacy of the Master. This expansion takes inspiration from some of the most memorable relationships in the ONE PIECE story, including Sanji and Zeff, Roronoa Zoro and Dracule Mihawk, and Monkey.D.Luffy and Silvers Rayleigh.

Each sealed box contains 24 English booster packs, with 12 cards in every pack, giving collectors and players a substantial opening experience and plenty of opportunities to find powerful new cards, alternate-art versions and rare pulls.

Legacy of the Master: The Bond Between Teacher and Student

The central theme of OP-12 is the relationship between masters and disciples. Rather than simply introducing another collection of characters, Legacy of the Master uses these connections as the foundation for new strategies and card interactions.

The set features memorable pairings such as Sanji and Zeff, Zoro and Mihawk, and Luffy and Rayleigh, making OP-12 particularly appealing to fans who enjoy the character relationships and history behind the ONE PIECE world.

The artwork also gives collectors plenty to appreciate, with cards inspired by the experiences shared between these iconic characters.

Six New Leaders and Fresh Strategies

OP-12 introduces six Leader cards with new effects, giving players new ways to approach deck building and gameplay. The set is designed around attribute- and event-focused strategies, while also providing cards that can work alongside existing decks.

That makes the ONE PIECE OP-12 Booster Box useful for both established players looking to improve their decks and collectors who want to explore the latest expansion. New cards can strengthen existing archetypes, while the new Leaders provide opportunities to build completely different strategies.
