Quick answer: OP17 (The World’s Strongest Warriors) is the One Piece Card Game 4th anniversary set, pre-releasing 21 August 2026 and fully releasing 28 August 2026. Aggregated from community openings totalling 1,000+ packs across three full cases plus additional boxes, every box carries the standard 7 Super Rares and 2 DON!!, but the premium hits are no longer mapped — a single box can hold anywhere from 1 to 4 hits. A full case averages about 22 hits (plus ~6–8 Panda Man alts) and reliably includes 4 alt-art leaders and 2 special DON!!, while the manga specials, Gold hockey SPs, Treasure Rare and the Pirates Crew alt-art grail are never guaranteed.
What Is OP17 — The World’s Strongest Warriors?
OP17, officially titled The World’s Strongest Warriors, is the One Piece Card Game’s 4th anniversary booster set and its first fully simultaneous worldwide release. It pre-releases on 21 August 2026 and fully releases on 28 August 2026. The set is built around the Four Emperors and the Elbaf arc, and it introduces a deep, self-contained Rocks Pirates archetype — openers noted you can build an entire Rocks deck using only cards from this set.
As an anniversary set, OP17 is unusually stacked with playable cards across every colour. Openers repeatedly described it as “mostly just full of good cards,” with all six new leaders — Kaido, Shanks, Charlotte Linlin (Big Mom), Sengoku and the Rocks/Luffy leaders — considered viable, plus staple characters and events for Rocks, Elbaf, and the Emperor crews. First-wave stock was tight, with boxes trading around $400–$650 USD at pre-release.
The set also debuts a new collector layer: hidden Panda Man alternate arts, and it stacks several premium tiers on top of the usual rarity ladder — Gold hockey SPs, Gold and Platinum DON!!, Treasure Rares, the manga specials, and the headline Pirates Crew alt-art grail. More on those below.
OP17 set highlights

- Pre-release: 21 August 2026 · Full release: 28 August 2026
Box Contents & Pack Structure
OP17 follows the standard One Piece TCG booster format:
- Booster Box — 24 packs per box, 12 cards per pack (7 SR and 2 DON!! per box on average)
- Double Pack Set (Vol.12) — 2 booster packs + 1 DON!! pack
- Case — 12 boxes (288 packs), following the usual One Piece case structure
The big structural change this set: OP17 dropped the fixed hit mapping. Older sets guaranteed a set number and position of hits per box; here the premium hits (alt arts, SEC, SP, manga, premium DON!!) are distributed randomly, so a box can produce anywhere from 1 to 4 hits. That is why case-level data is far more useful than any single box — and why our OP17 case mapping calculator prices each sealed box from the case average as boxes are opened, rather than pretending a fixed hit map still exists.
The Panda Man secret alt art occupies a rare slot (it carries a star, marking it as an alt art of a 2,000-power vanilla common) rather than the top hit slot — so a Panda Man does not cost you an SR, but it can take the place of one of the pack’s regular rares. It usually sits near the back of the pack, which fakes a lot of openers out.
OP17 Pull Rate Data — 1,000+ Packs
Bandai does not publish official hit rates for One Piece TCG. The table below is aggregated from community openings totalling 1,000+ packs — three full 12-box cases plus additional boxes. Rates are given per box (24 packs) and per case (12 boxes) so you can size a purchase either way. Because OP17 has no fixed hit map, treat per-box figures as averages with heavy variance.
| Card Type | Observed Frequency | Notes |
|---|---|---|
| Super Rare (SR) | 7 per box | Standard count; names recur rather than giving a playset (~6 Newgate, ~10 Kaido, ~10 Loki across one case) |
| DON!! (standard) | 2 per box | Two DON!! arts (Rocks / Four Emperors); one can upgrade to a Gold or Platinum finish |
| Total hits above SR | 1–4 per box · ~22 per case | No fixed mapping; a case recount landed 16 hits + 6 DON!! ≈ 22, or ~30 counting Panda Man |
| Alt-Art Leader | 4 per case | Kaido, Shanks, Charlotte Linlin, Edward Newgate seen; roughly one per 3 boxes |
| Alt Art / Parallel (AA) | Variable, 0–3 per box | Charlotte Linlin, Nico Robin, Luffy, Rocks, Beckman, plus recurring Loki AA |
| Secret Rare (SEC) | ~1 per 2–3 boxes | Loki SEC is by far the most common; one case produced five different Lokis |
| Gold Special Art (SP / hockey) | ~2 per case (not guaranteed) | Gold D. Roger, Yamato, Buggy, Shanks seen; a case can miss the second gold entirely |
| Manga-style Special Art | Rarest tier (not guaranteed per case) | Four Emperors mangas (Whitebeard, Big Mom, Kaido, Shanks) plus a manga leader/event — ~6 in the set |
| Treasure Rare (TR) | ~1 per case (not guaranteed) | A playable Edward Newgate TR; carries no X/manga marking, sits as a bonus hit |
| Special DON!! (Gold / Platinum) | ~2 per case | Typically one Gold + one Platinum; the Platinum (a.k.a. Diamond) is the rarer, ~$850 pre-release |
| Panda Man Secret Alt Art | ~6–8 per case | Six total (one per 2K vanilla); takes a rare slot, NOT a reliable one-per-box |
| Pirates Crew Alt Art (grail) | Case-level chase | Monkey D. Luffy / Rocks; the set’s most valuable card at ~$6,000 in Japan pre-release |
| God Pack | Confirmed, extreme tail | A rare replacement pack where every card comes as a hit (all alt art / SR and above); confirmed from community openings, no reliable rate yet |

Notable Pulls Across the Sample
Aggregated across the 1,000+ pack sample, these are the standout hits and what they say about OP17’s ceiling — and its brutal variance:
- 4 alt-art leaders per case — Kaido, Shanks, Charlotte Linlin (Big Mom), and Edward Newgate/Luffy leaders recur as the case’s reliable premium tier
- Gold hockey SPs — Gold D. Roger, Yamato, Buggy and Shanks all appeared; but one full case missed its second Gold SP, confirming they are not guaranteed
- Manga specials — the Four Emperors mangas (Whitebeard, Big Mom, Kaido, Shanks) are the rarest tier and skip most cases entirely
- Gold and Platinum DON!! — a case typically holds one Gold plus one Platinum; the Platinum (Diamond) was trading ~$850 at pre-release
- The Pirates Crew alt-art grail — the Monkey D. Luffy / Rocks card, ~$6,000 in Japan, sat above even the mangas and eluded most openers
- Loki everywhere — Loki appeared as SR, alt art and SEC repeatedly, with one case pulling five different Loki secrets
- Charlotte Linlin, Nico Robin, Rocks and Beckman alt arts — the mid-tier chases most openers actually walked away with
- ~6–8 Panda Man alts per case — recurring but unmapped; several boxes had none and a few had two
- God pack confirmed — community openings have confirmed an OP17 god pack, a rare replacement pack in which every card comes as a premium hit (all alt art / SR and above); it sits at the extreme tail of the distribution and is not something to open toward
Key finding: OP17’s dropped hit map is the whole story. Two boxes from the same case ranged from a four-hit “god box” to a single lonely alt art. A full case still delivers its 4 alt-art leaders, ~2 Gold SPs and 2 special DON!!, but the manga specials, Treasure Rare and the Pirates Crew grail are pure lottery — which is exactly why buying singles beats chasing a named card.
Top Chase Cards in OP17
Prices below are early pre-release figures and move fast — they firm up in the days after the 28 August 2026 launch. The list ranks the cards drawing the most collector and competitive attention.
| Card | Rarity / Type | Why It’s Chased | Market Price (USD) |
|---|---|---|---|
| Pirates Crew Alt Art (Luffy / Rocks) | Alt Art (grail) | The set’s most valuable card; a case-level chase that sits above even the mangas | ~$6,000 (JP, pre-release) |
| Four Emperors Manga Specials | Manga | Whitebeard, Big Mom, Kaido, Shanks; the rarest tier, not guaranteed per case | Premium — TBC |
| Platinum DON!! (Diamond) | Special DON!! | The rarest DON!! finish, roughly one per case; the case-opening showstopper | ~$850 (pre-release) |
| Gold Hockey SP (D. Roger, Yamato…) | Gold SP | Premium foiled special arts; ~2 per case and not guaranteed | Premium — TBC |
| Charlotte Linlin (Big Mom) — Alt Art | Alt Art | Called “insane” and “going to be in everything”; the headline mid-tier chase | Pre-release — TBC |
| Nico Robin — Alt Art | Alt Art | “10 out of 10 art”; strong 12-cost payoff character in the Elbaf shell | Pre-release — TBC |
| Edward Newgate — Treasure Rare | Treasure Rare | A genuinely playable blue TR; ~1 per case and not guaranteed | Pre-release — TBC |
| Panda Man Secret Alt Arts | Secret Alt Art | Hidden star-stamped variants of the six 2K vanillas; collector novelty, “one in every colour” | ~$2 each — TBC |
| Charlotte Pudding | Rare (playable) | “Basically an SR” — 3-cost 4k, on-play draw-three searcher; buy as a single, never chase | Pre-release — TBC |
Buy singles, don’t chase: The cheapest competitively playable OP17 cards — Charlotte Pudding, the Rocks 2k counters, Ben Beckman, Jack — are far cheaper as singles than the expected cost of hunting them through packs. Chase sealed only for the opening experience or the Panda Man / DON!! easter eggs. (Prices as of August 2026; cards move fast around release.)
The Panda Man Secret Alt Arts
The most talked-about new feature in OP17 is the Panda Man secret alternate arts. A card’s rare slot is replaced by a hidden Panda Man variant carrying a small star — the marker that makes it an alt art of an ordinary low-rarity character. There are six in total — exactly one per colour, three Commons and three Uncommons, with power from 4,000 to 8,000 and several of them carrying real card text — and a full case yields about 6–8 of them.
Two things surprised openers. First, Panda Man is not a guaranteed one-per-box: across the cases, some boxes had none and some had two, and they were scattered rather than seated in a fixed slot (usually near the back). Second, because Panda Man takes a rare slot rather than a common one, it can displace a regular rare — but it never eats your SR or top hit. Most Panda Man cards trade for only a couple of dollars, so treat them as a fun set-completion sub-chase, not a value driver.
For strategy: don’t open toward Panda Man. If you want the six, they are cheap singles once the set settles, and hunting them through sealed is the most expensive way to complete a $2-per-card sub-set.

Should You Open OP17 or Buy Singles?
Open OP17 if…
- You want the 4th anniversary opening experience — dense playable pools and strong artwork across every colour
- You’re hunting the Panda Man secret alts or the Gold / Platinum DON!! easter eggs, which are opening-only novelties
- You’re building a Rocks Pirates deck — the archetype can be built almost entirely from OP17
- You’re opening a full case, where the 4 alt-art leaders, ~2 Gold SPs and 2 special DON!! smooth out the per-box variance
Buy singles if…
- You want a specific chase — the Pirates Crew grail, a manga, or the Charlotte Linlin alt art cost far more to pull than to buy once prices settle
- You’re buying single boxes — with no fixed hit map, a box can deliver just 1 hit, so it’s a coin flip
- You need competitive staples — Charlotte Pudding, the Rocks 2k counters, Ben Beckman, and Jack are cheaper as singles than the margin on chasing them
The numbers on chasing the Pirates Crew grail
- The Pirates Crew alt art is a case-level chase — most full cases in the sample did not contain one
- At ~$6,000 in Japan, one grail is worth more than ten-plus sealed boxes at $400–$650 each
- Opening toward it means eating dozens of boxes of commons, dupes and $2 Panda Mans with no guarantee
- Even the “reliable” case hits (leaders, Gold SP, DON!!) rarely add up to the price of a single case
- Verdict: the grail, the mangas and named alt arts are all cheaper bought than chased — open for the experience, buy the target
The honest bottom line
OP17 is a genuinely fun anniversary set to open — the Panda Man easter egg, a self-contained Rocks archetype, and heavy artwork give every box something to chase, and a full case reliably delivers alt-art leaders, Gold SPs and premium DON!!. But OP17 dropped the fixed hit map, so single boxes swing wildly (1 to 4 hits), and no amount of opening is a good way to acquire a named card. If you want the Pirates Crew grail, a manga, or the Charlotte Linlin alt art specifically, buy the single after launch. If you want the experience, the DON!! and Panda Man hunts, or a Rocks deck, open a case and enjoy the ride.
Frequently Asked Questions
When is the OP17 (The World’s Strongest Warriors) release date?
OP17, officially titled The World’s Strongest Warriors, pre-releases on 21 August 2026 with full release on 28 August 2026. It is the One Piece Card Game 4th anniversary set and its first simultaneous worldwide release, built around the Four Emperors, the Elbaf arc, and a Rocks Pirates archetype. Booster boxes are the standard 24 packs, with a Double Pack Set (Vol.12) sold alongside.
How many SR are in an OP17 box?
Aggregated across 1,000+ packs, OP17 boxes carry the standard 7 Super Rares plus 2 DON!! each. Names recur rather than giving a clean playset — one full case produced roughly 6 Edward Newgate, 10 Kaido and 10 Loki across its SR, alt-art and secret slots. Hits above SR are not mapped: a single box can hold anywhere from 1 to 4 hits, while a full case smooths out to about 22 hits (16 hits plus 6 DON!!).
What are the Panda Man alt arts in OP17?
OP17 hides secret Panda Man alternate arts — a star-stamped Panda Man variant of a 2,000-power vanilla common that occupies a rare slot. There are six (one per vanilla common) and a full case yields roughly 6–8, but they are not a guaranteed one-per-box: some boxes had none, some had two, and they sit near the back of the pack. Most trade for only a couple of dollars — a novelty sub-chase, not a value driver.
What is the rarest / most valuable card in OP17?
The grail is the Pirates Crew alternate art — the Monkey D. Luffy or Rocks version — trading around $6,000 USD in Japan at pre-release, ahead of even the manga cards. Below it sit the Four Emperors manga specials (Whitebeard, Big Mom, Kaido, Shanks), the Gold and Platinum DON!! (the Platinum was ~$850 and lands roughly once per case), and the Gold hockey SPs. None of these are guaranteed in a case.
Is the Charlotte Linlin alt art worth chasing through packs?
Almost never. Alt arts, SPs, mangas and the premium DON!! are unmapped and land 1 to 4 per box at random, so pulling any specific named card — the Charlotte Linlin (Big Mom) alt art, a manga, or the Pirates Crew grail — costs far more on average than buying the single once prices settle after 28 August 2026. Open OP17 for the experience, the Rocks support, and the Panda Man and DON!! hunts; buy the single for a specific card.
How does OP17 compare to OP16 (The Time of Battle)?
OP16 introduced Treasure Rares and centred on Marineford. OP17 is the 4th anniversary set built around the Four Emperors, Elbaf, and a self-contained Rocks Pirates archetype. It keeps Treasure Rares (a playable Edward Newgate TR was pulled, though not guaranteed per case) and layers on new premium tiers — Panda Man secret alts, the Pirates Crew alt-art grail, Gold and Platinum DON!!, and Gold hockey SPs — but drops the old fixed hit mapping, so per-box variance is much higher than OP16.
