Legacy of the Master is the twelfth core booster set for the One Piece Card Game, releasing on August 22, 2025. Pre-release events will run from August 15–21, giving players promo packs that include Rainbow Luffy and an OP-11 Koby variant. Booster boxes and sealed cases are already trending at higher values, showing strong demand ahead of launch.
The set highlights mentor and disciple bonds, with Leaders featuring alternate arts that pair teachers and students. A new Sanji Treasure Rare adds another major chase, while the first Manga Rare Jewelry Bonney ties directly into the current anime arc. Most anticipated of all are the Silver and Gold Special Rare Marshall D. Teach cards, which continue the ultra-rare anniversary series.
10. Bartholomew Kuma #OP12-119 (Alternate Art)
This alternate art Secret Rare features Kuma in striking detail, making it a consistent chase card. Its appeal stems not only from aesthetics but also from its role in decks tied to Revolutionary Army strategies. Collectors value it as one of OP-12’s early standout pulls, giving it steady demand. With sealed boxes sitting above $120, this Kuma already shows signs of being a card worth holding.
9. Demon Aura Nine Sword Style Asura Blades Drawn Dead Man’s Game #OP12-037 (Alternate Art)
Roronoa Zoro’s iconic nine-sword technique gets a full alternate art treatment. The long attack name itself reflects the anime moment, which boosts collector nostalgia. It has competitive relevance, giving Green decks explosive finishing potential. As a thematic alternate art, it earns a higher slot in OP-12 value rankings.
8. Kuzan #OP10-082 (SP)
Originally from OP-10 Royal Blood, this Special Parallel Kuzan continues to carry weight with players and collectors. Featuring Garp’s disciple, Kuzan ties neatly into OP-12’s mentor theme. Its cycling ability keeps it relevant for competitive play, sustaining demand even across multiple sets. SP cards of Admirals consistently hold strong market floors, and Kuzan is no exception.
7. Roronoa Zoro #OP12-020 (Alternate Art)
Zoro’s new Green Leader instantly became one of the most talked-about reveals for OP-12. His alternate art pairs him with Dracule Mihawk, underlining their student-mentor bond. Both playability and the artwork push this card high on collectors’ radars. Green Leaders don’t always get spotlight treatment, making this a unique investment piece.
6. Tashigi #OP06-050 (SP)
This Special Parallel hails from OP-06 but remains a steady collector favorite. Tashigi’s following in the fanbase helps maintain strong aftermarket interest. The SP foiling gives it long-term collectability, aligning with the OP-12 chase for older SPs. Even without direct OP-12 ties, it’s recognized as a valuable part of the mentor-disciple legacy theme.
5. Portgas D. Ace #ST13-011 (SP)
From Starter Deck 13, this SP Ace variant continues to be highly sought after. Ace remains one of the most iconic characters, so any alternate or SP edition tends to command value. Its Starter Deck exclusivity makes it harder to find compared to booster pack pulls. Legacy of the Master re-elevates its importance by tying in to Ace’s mentor connections within the lore.
4. Zoro-Juurou #ST18-004 (SP)
A Special Parallel from Starter Deck 18, this version shows Zoro in his Wano identity. SP cards from recent Starter Decks have proven scarce in sealed circulation, driving collector premiums. The Wano setting makes this particularly collectible as it captures a pivotal story arc. With Zoro’s enduring popularity, this SP continues to trend upward.
3. Jewelry Bonney #OP12-118 (Manga)
The first-ever Bonney Manga Rare is one of OP-12’s biggest hits. The background showcases panels from the Egghead arc, connecting the card to current anime events. Manga Rares traditionally outperform most other pulls, and Bonney’s long-awaited treatment makes this one especially desirable. Collectors already see it as one of the most important cards in the set.
2. Marshall D. Teach #OP09-093 (SP) (Gold)
Part of the new Silver/Gold anniversary line, this Gold Special Parallel of Blackbeard is among OP-12’s hardest pulls. Anniversary SPs are only found once across multiple cases, keeping availability extremely low. Blackbeard’s role as a major antagonist ensures the card’s staying power. Gold versions are more limited than most chase cards, cementing its top-tier value.
1. Marshall D. Teach #OP09-093 (SP) (Silver)
The Silver variant is even more coveted, continuing the anniversary chase trend started with Gear 5 Luffy in OP-11. Its pull rate is exceedingly rare, estimated at one per several cases. Collectors view this as the pinnacle card of Legacy of the Master, both for scarcity and character significance. In terms of investment potential, it’s unmatched within OP-12.
Legacy of the Master is shaping up as one of the most collectible One Piece sets yet. Between the Bonney Manga, the Sanji Treasure Rare, and the Silver/Gold Blackbeard SPs, OP-12 delivers premium chase cards for both investors and anime fans. If you plan to secure these cards, joining Release Events and grabbing sealed product early will give you the best shot at hitting the set’s most valuable pieces.
