The One Piece Card Game’s post-anniversary momentum continues: Bandai’s official Card Game site announced BOOSTER PACK –THE WORLD’S STRONGEST WARRIORS– [OP-17], revealed during the One Piece Day ’26 window (official news posted August 21).

What was announced

• OP-17 booster pack: –THE WORLD’S STRONGEST WARRIORS– — the next mainline set
• New Speed Cards revealed: Nami (originally from OP-01) and Nico Robin (EB-05)
• BANDAI CARD GAMES Fest 26-27 in Orlando added to the events calendar

Context: the game that keeps growing

The Card Game is coming off a landmark stretch — it outsold a member of TCG’s traditional “big three” in back-to-back quarters earlier this year, and sealed product has been running hot all of 2026. OP-17 arriving into that market means expect: fast sellouts at launch, scalper premiums on sealed boxes (buy from reputable retailers, never scalpers), and a competitive meta shift as the set settles.

Our advice stands: pre-order from official retailers if you want sealed product, and treat singles on the secondary market with patience — prices usually calm down a few weeks after release.
