What Is OP16 — The Time of Battle?
OP16, officially titled The Time of Battle, is a One Piece Card Game booster set released on May 30, 2026. It covers the Impel Down and Marineford (Summit War) arcs — arguably the most emotionally charged chapters in all of One Piece — centred on Ace's execution, Whitebeard's final stand, and Blackbeard's rise.
The set is significant beyond its card pool for one major reason: OP16 is the first One Piece Card Game set released in Japan to include Treasure Rares (TR), a rarity tier that had previously only appeared in English product. This is a landmark shift in the Japanese set structure and places OP16 at the top of collector attention for that reason alone.
The six leader cards in OP16 — Sengoku, Blackbeard (Teach), Ace, Yamato, Buggy, and Luffy — are drawn from across the Marineford conflict, with alternate art parallel versions available for select leaders. The set's 155-card total spans Common through Treasure Rare, with a rarity ladder designed to reward both casual openers and serious hunters.
OP16 set highlights
- Arc: Impel Down and Marineford (Summit War) — Ace's execution and Whitebeard's last battle
- Leaders: Sengoku, Marshall D. Teach (Blackbeard), Portgas D. Ace, Yamato, Buggy, and Monkey D. Luffy
- New rarity in Japan: Treasure Rare (TR) — the first time this tier has appeared in a Japanese One Piece TCG release
- Chase SP: Miss All Sunday (Nico Robin) — widely considered the most sought-after SP in the set
- Chase SECs: Marshall D. Teach (Blackbeard), Portgas D. Ace, and an alternate art Ace SEC
- Total cards: 155
- Packs per box: 24 (Japanese and English)
- Release date: May 30, 2026
Box Contents & Pack Structure
OP16 follows the standard One Piece TCG booster box format:
- Booster Box — 24 packs per box, 12 cards per pack
- Double Pack — 2 packs + 1 DON!! pack (contains the Gold DON!! chance)
- Case — 12 boxes (288 packs) for both Japanese and English
Each pack contains a mix of Commons, Uncommons, Rares, and a foil hit slot. Not every pack yields an SR or higher — most packs will produce a standard Rare or foil Common in the hit slot. The SR rate of 3–4 per box means roughly 1 in every 6–8 packs produces a Super Rare.
The DON!! pack (included with double packs, not loose blisters) is where Gold DON!! cards are found. If Gold DON!! is on your list, buy double packs rather than individual blisters.
Top Chase Cards in OP16
Miss All Sunday SP — The Set's Chase Pull
The Miss All Sunday SP (Nico Robin) is the clear top chase for collectors in OP16. Multiple release-day openers independently identified it as the most sought-after SP in the set, with one opener calling it "probably the most expensive one." The artwork features Robin surrounded by flower petals with detailed hair texturing and foiling — widely praised as one of the most visually striking cards in the set. If you are chasing the best SP in OP16, this is the one.
Marshall D. Teach (Blackbeard) SEC
The Blackbeard Secret Rare is a standout for both competitive and collector audiences. The card features wave-like texturing leading into Blackbeard's outstretched hand, black-hole effect detailing, and glossed jewellery and bracelet elements. Multiple openers paused to highlight the texturing quality. As the arc's primary antagonist and one of the most anticipated leaders for deck building, demand for this SEC is expected to be sustained.
Portgas D. Ace SEC (Standard & Alternate Art)
OP16 contains two Ace Secret Rares: a standard SEC and an alternate art SEC. The standard SEC features foiling with wave detail and glossed tattoo artwork. The alternate art version elevates the treatment further with a different illustration. Ace is the emotional centrepiece of the Marineford arc and consistently ranks among the most pulled chase characters in One Piece TCG. Both versions are worth acquiring.
Yamato SR
The Yamato Super Rare was the most praised SR across all three release-day opening sessions reviewed. The black attribute treatment and card art were highlighted as exceptional quality, with multiple openers naming it their favourite SR in the set. Strong collector and competitive interest makes this the top SR target.
Boa Hancock SR
The Boa Hancock Super Rare drew enthusiastic responses on release day, with one opener describing it as their favourite SR from OP16 and calling it "absolutely stunning." The Byakuya Zanmaru artwork and detailed illustration are consistent with Boa's strong track record as one of the most collectible characters in the game.
Alternate Art Leader Cards
OP16's parallel leader cards were among the most anticipated pulls ahead of release. Openers specifically called out the Luffy and Teach (Blackbeard) alt art leaders as their personal targets. The Yamato alternate art leader was highlighted as "one of the most beautiful arts I've ever seen" in a Japanese case opening. If alt art leaders are your chase, Yamato, Luffy, and Teach are the primary targets.
OP16 Pull Rate Data by Rarity
Bandai does not publish official hit rates for One Piece TCG. The estimates below are derived from multiple documented OP16 release-day openings: a 4-box English session, a full 12-box Japanese case (288 packs), and a single English box (24 packs). These are community estimates, not guarantees.
| Card Type | Per Pack (est.) | Per Box — 24 packs (est.) | Per Case — 12 boxes (est.) | Notes |
|---|---|---|---|---|
| Super Rare (SR) | ~1 in 6–8 | ~3–4 | ~36–48 | Consistent with standard One Piece TCG SR rate; most boxes land 3–4 |
| Leader (standard foil) | — | ~2–3 per box | ~24–36 per case | 6 unique leaders in OP16; all 6 confirmed in 4-box English opening |
| Alt Art Rare / Parallel R | ~1 in 24–36 | ~1 per box | ~8–12 per case | Replaces a Rare slot; Moby Dick and Ace alt arts pulled in documented openings |
| Alt Art Leader (Parallel Leader) | ~1 in 72–144 | ~1 per 3–6 boxes | ~2–4 per case | Yamato, Luffy, and Teach parallels highlighted; pulled once per 12-box Japanese case |
| Secret Rare (SEC) | ~1 in 48–72 | ~0.4–0.5 per box | ~4–6 per case | Not guaranteed per box; Blackbeard and both Ace versions confirmed in set |
| SP (Special Rare) | ~1 in 168–192 | ~1 per 7–8 boxes | ~1–2 per case | Miss All Sunday (Robin) is the top SP target; Ace SP also confirmed; 1 SP in Japanese 12-box case |
| Manga Rare | Very rare | ~0 per box | ~3 per case | 3 Manga Rares (Monkey D. Luffy, Kobe confirmed) pulled from full Japanese case; not guaranteed |
| Gold DON!! | ~1 in 288 | ~1 per 12 boxes | ~1 per case | Found exclusively in DON!! packs (double packs only, not loose blisters) |
| Treasure Rare (TR) | Unknown | Unknown | Unknown | First Japanese One Piece set with TR; zero pulled in all documented early openings — likely extremely rare |
Box Opening Results
English box — single 24-pack opening
A documented single English box opening of OP16 (24 packs) produced the following hits:
- Sakazuki (Akainu) SR
- Boa Hancock SR — described as "my favourite super rare from this set"
- Kimmon SR
- Edward Newgate (Whitebeard) SR
- Blackbeard SEC (Secret Rare)
- Sangoku leader, Buggy leader, and 1–2 additional leader pulls
Summary: 4 SRs, 1 SEC, 3–4 leaders from a single English box. No alt art or parallel in this box. The SEC pull was the clear highlight. This result falls within the normal range for a single box.
English 4-box session highlights
A separate English 4-box opening produced the following premium pulls across all four boxes:
- Box 1: Secret Rare Ace, Alternate Art Secret Rare Ace, SR Buggy, SR Edward Newgate (Whitebeard)
- Box 2: SR Mr. 3, Alternate Art Moby Dick (rare), Alternate Art Ace (rare), SR Yamato, SR Luffy
- Box 3: SR Mr. 3, SR Buggy, SEC Blackbeard
- Box 4: SP Miss All Sunday (Robin), SEC Ace
SR summary across 4 boxes: Buggy ×3, Mr. 3 ×3, Sakazuki ×3, Whitebeard ×2, Luffy ×1, Yamato ×1, Kimmon ×1. This indicates certain SRs appear at higher frequency — typical of One Piece TCG distribution where 2–3 SRs per colour pool recur more frequently than others.
Hits across 4 boxes: 1 SP (Miss All Sunday), 2 SECs (Blackbeard, Ace), 2 Alt Art SECs (Ace alt art was in the same box as the standard Ace SEC — a double-hit box). All 6 leaders pulled by end of session.
Key takeaway from box-level data
A "good" OP16 box lands 4–5 SRs with either an alt art or a SEC. A standard box produces 3–4 SRs with no premium hit beyond an occasional alt art rare. A "bad" box can produce 3 SRs and nothing else. All are within normal range. The SP and Manga Rare are case-level (or rarer) targets — do not expect them from a single box.
Case Opening Results — 288 Packs (Japanese)
A full Japanese case opening of OP16 (12 boxes, 288 packs, purchased at approximately $1,150 USD) was documented on release day. This is the most comprehensive early dataset available for the set.
Premium hits by box:
- Box 1: SEC Blackbeard, 4 SRs, Gold DON!!
- Box 2: Alt Art SR (Boa Hancock), 3 SRs
- Box 3: Gold Don card (stage/event), SEC pull
- Box 4: SEC (second of case)
- Box 5: Alt Art SR (Boa Hancock second pull) + SRs
- Box 6: Yamato Alt Art Leader parallel, 3 SRs — noted as "best box of the case"
- Box 7: SP Ace, 2 SRs
- Box 8: 4 SRs, Alt Art Rare
- Box 9: Alt Art SR Blackbeard (duplicate), additional SRs
- Box 10: Alt Art SR + SRs
- Box 11: Manga Rare (Monkey D. Luffy), Manga Rare (Kobe), SEC pulls
- Box 12: Manga Rare (third of case), SEC
Case totals (12 boxes / 288 packs):
- Manga Rares: 3 (Monkey D. Luffy, Kobe, and one additional)
- SP cards: 1 (Ace SP, pulled in Box 7)
- SEC cards: approximately 4–6 across the case
- Alt Art Leader parallels: 1 (Yamato, Box 6)
- Gold DON!!: 1 (Box 1)
- Alt Art Rares: multiple across the case
- Treasure Rare (TR): 0 pulled
Case-level observations
Several distribution patterns emerged from this case that are typical across One Piece TCG sets:
- "Alternate box" mechanic: boxes with a Parallel Alt Art Rare appear to trade one SR slot for the alt art hit — a standard SEC + alt art box yielded 3 SR instead of the expected 4
- SEC clustering: multiple SECs appeared in the same box (the final boxes), rather than distributing evenly — case distribution is not uniform
- SP rarity: only 1 SP across 288 packs — the SP rate is genuinely sparse, not a guaranteed case pull
- Manga in final boxes: both Manga Rares pulled late in the case — this is not unusual but is also not predictable
- No TR: zero Treasure Rares across the full case — early data suggests TR is ultra-rare or requires specific conditions to appear
Treasure Rares: New to Japan in OP16
OP16 marks a milestone: it is the first One Piece Card Game set released in Japan to include Treasure Rares (TR). This rarity tier had previously only existed in English product. The addition of TRs to the Japanese set structure is a significant change for the game's collector landscape.
What we know about TR hit rates in OP16
- No official TR hit rates have been published by Bandai
- Zero TRs were pulled across all documented early openings — including a full 12-box Japanese case (288 packs) and multiple English box sessions
- Based on comparable products where TR-tier cards exist (English One Piece sets and other TCGs), TRs are expected to appear at roughly 1 per case or rarer
- The absence of any TR pull in early data suggests the rate may be lower than 1 per case, or that TRs require specific pull conditions not yet publicly documented
What this means for collectors
The introduction of TRs into Japanese OP sets creates a new category of ultra-chase cards above the existing Manga Rare tier. If the English TR framework applies, expect TRs to be worth significant multiples over any SR or SEC in the same set. Until more case data emerges, do not plan your opening strategy around pulling a TR — treat it as a windfall if it happens.
Should You Open OP16 or Buy Singles?
If you want Miss All Sunday SP
Buy the single. At roughly 1 SP per 7–8 boxes across a case, and with multiple SPs in the set competing for that slot, the expected cost to pull Miss All Sunday specifically through box openings is multiples of the card's secondary market price. Check current listings — SP prices for a new set stabilise within the first two weeks as opening volume increases.
If you want Blackbeard or Ace SEC
SECs in OP16 appear at a better rate than SP — roughly 4–6 per case, or 0.4–0.5 per box. If you are chasing a specific SEC and enjoy opening, 2–3 boxes gives you a realistic (not guaranteed) shot. For a specific SEC target, buying the single is still more cost-efficient unless you want the opening experience.
If you want to build competitive decks
The competitive SRs (Yamato, Boa Hancock, Sakazuki, Luffy) are obtainable within 1–3 boxes with reasonable luck, or more reliably through singles. OP16 does not require SPs or SECs for competitive play — source your playsets through a combination of opening and targeted single buys.
If you want to open for the experience
OP16 is a genuinely enjoyable opening product. The Marineford arc artwork is exceptional — multiple openers paused specifically to praise the card finishes, texturing, and foiling quality. The SR rate of 3–4 per box is consistent, and the alt art Rare slot gives every box a realistic premium hit. Set a comfortable budget, expect 3–4 SRs, and enjoy the opening without chasing a specific SP or Manga.
If you are buying sealed for value
Marineford is one of the most emotionally resonant arcs in One Piece history, and Ace and Whitebeard are perennially among the most collected characters in the game. Combined with OP16 being the first Japanese set with Treasure Rares — a landmark change in the set structure — sealed OP16 product has strong collector anchor potential. Store sealed boxes in a cool, dry environment away from direct light.
Frequently Asked Questions
Does every OP16 box have a Secret Rare?
No. Based on case opening data, SECs appear at approximately 4–6 per 12-box case — an average of 0.4–0.5 per box. Most individual boxes will not contain a SEC. Boxes that do yield a SEC or SP are referred to as "hit boxes" and typically have slightly fewer SRs to compensate.
What are the OP16 Manga Rares?
OP16 contains at least three Manga Rare cards, with Monkey D. Luffy and Kobe confirmed in the documented Japanese case opening. Manga Rares appear at approximately 3 per full case (288 packs) based on early data — but this is not guaranteed, and many cases will yield fewer. They are among the hardest pulls in the set, comparable to the Enel and Gear Five Mangas from previous sets.
Is the Buggy leader deck good in OP16?
Two separate openers independently expressed enthusiasm for building the Buggy leader deck after seeing the cards. One noted they "want to build this deck, I want to try it out," while another mentioned "I actually want to build this deck." The Buggy leader is a lower-cost entry point compared to Blackbeard or Luffy builds and may appeal to players looking for a fun alternative. Check current tournament results as the meta develops.
What does the X regulation mark mean in OP16?
OP16 cards carry an "X" regulation mark in the bottom right corner, replacing the previous numbered marks (1, 2, 3, 4, 5). One documented opener noted this and speculated it may indicate that X-marked cards remain playable indefinitely as the game aligns Japanese and English release schedules. Bandai has not published an official explanation as of the set's release date — check official tournament rules for the current legality table.
Is OP16 hard to get?
Yes — multiple openers documented significant difficulty obtaining OP16 product on release day. One waited from 4:00 a.m. outside a convenience store only to have the boxes split among a larger-than-expected queue. Another secured a case through a personal connection with a shop owner willing to order One Piece product specifically. Scalping and bulk purchasing by resellers have made OP16 notably harder to buy at retail than previous sets.
How does OP16 compare to OP15 hit rates?
OP16 is broadly comparable to OP15 at the SR, SEC, and SP tier. The key differences are: OP16 introduces Treasure Rares to the Japanese market for the first time, and OP16's Manga Rare rate appears slightly higher (3 per case vs OP15's 0–1 per English case). Both sets maintain the same 3–4 SR per box floor and the same ~1 SP per 7–8 box expectation.
