One Piece Card Game OP-17 (titled “The World’s Strongest Warriors” and also known as “Adventure on Kami’s Island”) is the game’s landmark 4th Anniversary Booster Set. It marks the rollout of simultaneous global worldwide releases, introduces the Elbaf arc, and features highly sought-after chase cards.

Case Value & Pull Rates
Because OP-17 is a large anniversary set, cases are highly prized for featuring ultra-rare chase cards, including special alternative arts and manga-style head artwork. According to community feedback and historical TCG case mapping, each standard English case generally guarantees specific “hits” (such as multiple Alternate Art Leaders and Special Parallel cards), which often causes sealed cases to trade at a premium over individual loose boxes
