What is OP-17 “The World’s Strongest Warrior”?
“The World’s Strongest Warrior [OP-17]” is the 17th booster pack for the ONE PIECE Card Game. It serves as the 4th Anniversary commemorative pack, marking four years since the game launched in 2022. As the name suggests, the set spotlights the toughest fighters gathered in Elbaf along with the Four Emperors who sit at the very top of the pirate world.
Since its 2022 debut, the ONE PIECE Card Game has steadily rolled out booster packs and starter decks. With new starter decks recently released to welcome beginners, this anniversary booster arrives at a strong moment for the game. OP-17 pulls the momentum of the manga’s latest “Elbaf arc” straight into the cards, offering plenty for veteran players and returning fans alike.
Release date and price
The official ONE PIECE Card Game site lists the following details for OP-17.
Saturday, August 22, 2026
240 yen (tax included)
6 cards per pack / 24 packs per box
The 240 yen (tax included) per pack figure comes from the official listing. There has been chatter about a price revision from previous sets, so always confirm the final price on the official product page. Buying by the box (24 packs) is popular with collectors and deck builders who want to open a large batch at once.

Cards: Four Emperors and the Elbaf arc
True to its name, the highlight of OP-17 is a lineup of Emperor-level power cards and Elbaf arc characters. Here are the main cards confirmed so far from official artwork and preview info.
Confirmed leaders and standout cards
One of the Four Emperors joins as a leader card, revealed in the red color. He is one of the flagship cards of the anniversary set.
A new black-color leader shown for the first time, with a parallel version also teased. His freshly drawn Elbaf-arc outfit is drawing plenty of attention.
Loki, a giant with a major presence in the Elbaf arc, is confirmed as a secret rare, a must-have for fans of the arc.
Many more Elbaf arc characters are said to be included, and fans are hopeful about appearances from the likes of the Rocks Pirates and Roger Pirates, names truly worthy of “the strongest.” The complete card list will be released by the publisher in stages, and we will update as details emerge.

The first set with a global simultaneous release
Another major talking point is that OP-17 is the first set in a global simultaneous release. Previously the Japanese and overseas editions launched on different dates, but from this pack onward players around the world can get the new set on the same day.
This matters for the competitive scene and card prices alike: regional information gaps shrink, and the metagame starts moving worldwide the moment the set drops. Combined with the anniversary hype, expect concentrated collector demand and likely shortages and pre-order rushes ahead of launch.
Pack structure and rarities
Like previous boosters, OP-17 is expected to feature the usual rarities: leader, common, uncommon, rare, super rare, secret rare and special cards. Anniversary sets traditionally pack in special parallels and newly drawn illustrations, and this time too there are multiple chase cards such as the Luffy parallel.
Exact card counts per rarity and the total number of cards are being released gradually by the publisher as of writing. Pull rates and chase cards will become clear closer to launch, so check the latest official info when planning your deck or collection.

How to pre-order and get it
As an anniversary set and the first global simultaneous release, OP-17 is expected to be even harder to grab than usual. If you want it, lock in one of these routes early.
- Hobby / card shop pre-orders: Booking by the box is the surest route; some shops run lottery sales.
- Online stores (Amazon, etc.): Pre-order pages appear, but popular sets sell out fast, so set up alerts.
- In-store on release day: Stock varies by shop, and lines may form before opening for a set like this.
The publisher may announce made-to-order or lottery details, so watch the official site and retailer notices if you want to secure it.
Reactions on social media
“A global simultaneous release on the 4th anniversary set, the meta is going to shift fast.”
“Whitebeard as a red leader is huge, and I need that Elbaf-arc Loki.”
Following the official artwork reveal, fans are excited about the Emperor leaders and Elbaf arc cards, while many also worry about shortages and are hunting for pre-order info.
