The One Piece Card Game's next major English booster set, OP-17: The World's Strongest Warriors, is officially scheduled for release on August 28, 2026, according to Bandai's official product announcement. The set marks the game's 4th anniversary and centers on the Elbaf Arc, bringing the Four Emperors into the spotlight in a way the game hasn't done before.
For collectors and players who have been following the Elbaf storyline in the anime and manga, this is one of the more anticipated sets on the 2026 calendar. It also means a fresh wave of sealed booster boxes and chase pulls that are worth protecting from the moment they hit shelves.
This guide covers what's confirmed about OP-17 so far, why the Elbaf Arc theme matters for this set specifically, and which EVORETRO products fit the booster box format collectors will be opening.
Bandai's official announcement, made during the Next Plan Presentation on June 18, 2026, confirmed the set's theme centers on the Elbaf Arc and the Four Emperors. Early card reveals point to cards featuring Loki, the Cursed Prince, and Monkey D. Luffy in giant-clan armor, both tied directly to the Elbaf storyline.
As with most Bandai TCG announcements, full set details and the complete card list typically follow closer to release, so treat early reveals as a preview rather than the complete picture.
The Four Emperors are some of the most recognizable characters in the One Piece franchise, and previous sets that lean into major storyline characters tend to generate stronger secondary market interest than sets built around smaller arcs. Combined with the 4th anniversary framing, OP-17 has the ingredients for a higher-demand release than a typical quarterly set.
That combination, major characters plus a milestone anniversary, is usually a signal to have protection ready before the set even hits shelves, rather than scrambling once boxes are already selling out.
However the set performs once it's out, a sealed booster box only holds its value if the box itself stays in shelf-fresh condition. Corner crushing and shrink wrap damage are the most common ways a sealed box loses value before it's even opened.
For English booster boxes in this OPP format, EVORETRO's One Piece Booster Box PET Protectors are sized to fit this exact box format, keeping the box art and corners protected through everyday handling and storage.
If you'd rather display a sealed box than tuck it away, EVORETRO's acrylic display case for One Piece booster boxes gives the box a rigid, dust-free shelf presence while still showing off the printed art.
If you're opening OP-17 rather than holding it sealed, the Manga Rare and Super Parallel treatments confirmed for Four Emperors cards in earlier sets suggest this release will carry similarly premium chase variants. Those pulls are worth sleeving and top loading immediately after opening, since corner and surface wear starts the moment a card leaves the pack.
Given the Elbaf and Four Emperors theme, expect strong demand for any Luffy, Shanks, Kaido, or Big Mom pulls in particular, which makes fast protection worth prioritizing for those specific cards.
OP-17 arrives roughly a month after the Starter Deck ST31โ36 wave that launched July 31, 2026, and it's followed by the Extra Booster Heroines Edition vol. 2 in October and Premium Card Collection Best Selection vol. 7. That gives collectors a fairly dense stretch of releases across August through October, which is worth planning storage and budget around rather than treating each set as an isolated purchase.
For collectors trying to prioritize, a major numbered booster set like OP-17 tends to carry more long-term relevance to the competitive card pool than a themed extra booster or collector-focused product, which is one reason it's worth treating as a higher priority for both budget and protective supplies.
To get ahead of the OP-17 release, start with these:
Bandai's official announcement confirms an August 28, 2026 release date for the English version, alongside the Elbaf Arc theme.
The set is themed around the Elbaf Arc and the Four Emperors, marking the game's 4th anniversary.
That depends on your goals. If you're holding for resale or display, protect the box immediately. If you're opening for chase pulls, have sleeves and toploaders ready before you start.
Bandai typically releases full set details closer to the launch date, so treat early reveals as a partial preview rather than complete information.
OP-17: The World's Strongest Warriors looks like one of the more significant One Piece Card Game releases of 2026, combining a major storyline arc with the game's 4th anniversary. Whether you're planning to hold sealed boxes or chase specific pulls, having the right protection ready before release day is the easiest way to make sure the excitement doesn't cost you box or card condition later.
Keep an eye on official channels as the August 28 release date approaches for the full card list and confirmed pull rates.
