What is OP-17?
OP-17 is the seventeenth main booster set for the One Piece Card Game, officially titled The World's Strongest Warriors. Bandai has positioned it as the game's 4th anniversary set, and the card list leans into that milestone.
Three themes headline the set on Bandai's official OP-17 page. The Straw Hat crew arrives in Elbaf, the Rocks Pirates era gets its own cards, and the Four Emperors appear as Super Alt-Arts. There's also a Super Leader Alt-Art Monkey D. Luffy for the anniversary.

OP-17 release dates for Australia
There's no separate Australian date. Bandai publishes one English release date covering Oceania alongside North America and Europe, and that date is 28 August 2026.
Japan gets the set on 22 August 2026. Stores in the English regions can also run pre-release events from 21 August, a week before general release.
Bandai's 4th Anniversary Event runs in stores from 21 August to 13 September 2026, and Australia is in the eligible regions. If you play locally, our Melbourne TCG events guide covers where to find One Piece tournaments.
One honest caveat: TCG release dates can shift close to launch. If anything moves, alert subscribers hear about it first.
What's inside The World's Strongest Warriors
Bandai lists the set at "131+4 types in total", with each booster pack holding six cards.
The anniversary framing shows in the chase cards. The Elbaf arc brings the Straw Hats in their Elbaf outfits plus Loki. The Rocks Pirates cards cover Rocks D. Xebec's crew, including a young Edward Newgate and Charlotte Linlin. On top of that sit the "Four Emperors, Assemble" Super Alt-Arts: Newgate, Shanks, Kaido and Linlin.
Bandai hasn't published the English box configuration or full leader lineup on its official pages yet. We'd rather leave those out than repeat retailer guesses, and we'll update this page once Bandai confirms them.
How OP-17 preorders work at Drop Store
Preorders here work the same for every set. You pay when you order, and your sealed product ships tracked from Melbourne once stock arrives.
Two terms to know before you commit. Preorder sales are final, and a mixed cart ships together on the latest release date in it. Orders over $99 ship free Australia-wide.
One Piece TCG at Drop Store
We stock sealed One Piece product by official set code in our One Piece TCG collection. That's where you'll find OP-16 The Time of Battle, OP-13 Carrying On His Will, the DP-11 double pack and Illustration Box Vol. 8.
Sealed One Piece moves quickly. OP-14 The Azure Seas Seven sold out here, and that's exactly why the alert list exists. The same alerts cover Pokemon TCG too, including everything in our 2026 release calendar.
