Since Bandai launched the One Piece Card Game internationally in 2022, it's grown from a niche import curiosity into one of the fastest-rising trading card games on the market. If you're catching up on the set history or deciding where to jump in, here's the landscape.
How One Piece Card Game Sets Are Structured
Main expansion sets release under the "OP" prefix (OP-01, OP-02, and onward), roughly every few months. Alongside main sets, Bandai releases smaller side products — Starter Decks (ST-prefix), Extra Boosters (EB-prefix), and Premium Card Collections featuring alternate-art reprints of chase cards from earlier sets.
The Early Era: OP-01 Through OP-05
The foundational sets introduced the game's core mechanics and its earliest chase cards — Leader cards for the series' most iconic characters (Luffy, Zoro, Sanji, Whitebeard) and the first wave of alternate-art "Parallel" cards. Early-set Parallel Leaders from this era, particularly from OP-01, carry some of the strongest long-term value in the game precisely because early print runs were smaller before the game's international popularity was fully understood.
The Growth Era: OP-06 Through OP-09
As the game's competitive scene matured, these sets introduced more complex mechanics and expanded the roster of playable Leaders significantly, including major arcs like Wano and Egghead. Secondary market activity on chase Parallels from this era has been consistently strong, driven by both collectors and an increasingly competitive tournament scene.
The Current Era: OP-10 and Beyond
OP-10: Royal Blood is the most recent major expansion, continuing the game's momentum with new Leader mechanics and alternate-art chase cards tied to some of the story's most significant arcs. New sets continue to be covered as they release on The Empire Report.
Sealed Product vs. Singles for One Piece
Booster boxes are fun to open, but One Piece Card Game's most valuable cards are heavily concentrated in a small number of chase Parallels per set — meaning most individual packs won't contain a high-value pull. If you know which specific Leader or Parallel you want, buying the single directly is almost always the more predictable route.

Protecting Your Cards
One Piece Card Game cards use the same standard card stock as most modern TCGs — sleeve and toploader every card you plan to keep long-term. Our storage and protection guide covers exactly what to use.
