OP16 Hit Rates & Case Opening Guide (2026)

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
• Total SRs: 10 — notably fewer than OP14 (14) and OP15 (15), meaning more copies of each SR per box
• Packs per box: 24 (Japanese and English)
• Regulation mark: X — OP16 replaces the previous numbered regulation mark system (1–5) with an "X" on SR and below; some SECs still carry a "5" mark
• 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. OP16 contains only 10 SRs (compared to 14–15 in OP14 and OP15), meaning there are fewer unique SRs but each appears more frequently per box — approximately 4–7 SRs per box across documented case data, with 7–8 copies of each SR name appearing in a full 12-box case. Note: in OP16, leader packs are no longer "dead" packs — they can now also contain an SR, unlike in previous sets where a leader pack signalled no other hit nearby.

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 Top 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.

SP Cards in OP16 — Miss All Sunday, Ace, Cavendish, Kuma

OP16 contains at least four confirmed SP (Special Parallel) cards: Miss All Sunday (Nico Robin), Portgas D. Ace, Cavendish, and Kuma. Miss All Sunday is the clear top value SP and the one most openers target. Cavendish SP was confirmed pulled from a pre-release box, with the opener calling it an unexpected highlight. Kuma SP has also been confirmed in community opening data. SP boxes are always 2-hit boxes — if your box contains an SP, it will not also contain a SEC or alt art leader; the SP is the box's premium hit.

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 English OP16 openings: two single English box sessions, a 4-box English session, and a full 12-box English case (288 packs). Japanese case data (576 packs across two cases) is included as a comparison reference where relevant. These are community estimates, not guarantees.

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 box — second documented single-box opening

A second English box opening produced the following hits:

• Buggy SR, Yamato SR, Sakazuki SR (×2), Kinmon SR — 4 SRs total including one alt art duplicate
• Ace SEC (Secret Rare)
• Gold DON!! (pulled mid-box)
• Alt Art Kinmon (alt art appeared alongside its standard SR counterpart in the same box)
• Alt Art Sakazuki (alt art also appeared in the same box as the regular Sakazuki SR)

Summary: A four-hit box (SEC + Gold DON!! + 2 alt arts) with 4 SRs. Notable: both Kinmon and Sakazuki each appeared as both regular SR and alt art in the same box — confirming alt arts do not replace their base SR in the pack slot. Vista TR was pulled in its regular (non-TR) form, confirming it exists in the set as a card.

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 — English Case (288 Packs)

The primary dataset for this guide is a full English 12-box case opening (288 packs). Japanese case data is included in a separate comparison section below.

English Case — full hit breakdown

One documented English 12-box case produced the following results. Note: this case had anomalously high SP distribution — the hit type breakdown was unusual, but total hit count was normal.

• SPs: 5 total — 2× Nico Robin (Miss All Sunday), 1× Ace, 1× Kuma, and one additional; opener described this as "unprecedented" and "never seen before." Normal English expectation is ~2 SPs per case.
• SECs: 5 total — 3× Blackbeard, 2× Ace; below the expected ~8 per English case. The extra SPs appear to have come at the expense of SECs.
• Treasure Rare: 1× Vista TR — the only confirmed TR pull across all documented opening data
• Gold DON!!: 1 (expected: ~2 for English)
• Leaders: 3 (expected: ~4); Luffy and Buggy confirmed
• Alt art rares: Marco AA, Luffy AA, Buggy Leader AA, Crocodile AA
• Manga Rares: 0 pulled

What this case tells you: Hit types trade off within a case rather than stacking independently. An unusually SP-heavy case will typically run light on SECs and vice versa. The expected English case distribution (from openers familiar with multiple cases) is: ~2 SPs, ~8 SECs, ~2 Gold DON!!, ~4 leaders. This case skewed heavily toward SPs; treat the SP result as an outlier, not the norm.

Case-level observations (English)

Patterns consistent across English case data:

• SP boxes are 2-hit boxes: a box containing an SP will not also contain a SEC — the SP is the box's premium hit and no additional SEC competes with it
• "Alternate box" mechanic: boxes with an alt art rare appear to trade one SR slot for the alt art hit
• SEC distribution: SECs can cluster — multiple SECs in the same box rather than spreading evenly is documented and normal
• TR is not guaranteed: Vista TR was pulled from this English case, but the rate is likely sub-case (1 per case or rarer); treat it as a windfall
• Alt arts do not replace base SRs: a card can appear as both its regular SR and alt art version in the same box, as confirmed in single-box data

Japanese cases — for comparison

Two Japanese 12-box cases (576 packs combined) were documented separately. English and Japanese cases use different distribution structures:

• SECs per case: Japanese ~4 (stated as case guarantee); English ~8 (2 of each of 4 SECs)
• SPs per case: Japanese ~1; English ~2
• Gold DON!! per case: Japanese ~1; English ~2
• Manga Rares: confirmed in Japanese cases (~3 per case: Monkey D. Luffy, Koby, and one additional); not confirmed from English case data
• Treasure Rares: 0 pulled across 576 packs of Japanese product; 1 Vista TR from the English case

One Japanese case was notably light — only 1 SP across 12 boxes, with the opener explicitly calling it "a really bad case." This illustrates that SP distribution in Japanese cases can fall below even the ~1-per-case expectation.

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

• Vista is the confirmed TR card in OP16 — multiple openers pulled the regular (non-TR) Vista card and confirmed the TR version exists
• No official TR hit rates have been published by Bandai
• 1 TR was pulled from one documented English 12-box case (288 packs); zero TRs from two documented Japanese 12-box cases (576 packs combined)
• TR appears to occupy an alt art slot rather than the dedicated rare slot — it is not a separate guaranteed pull type
• Based on available data, TR is less common than 1 per case in Japanese product; English product appears to have a slightly higher TR frequency
• Some openers noted that the TR version of Vista was considered a weak TR choice for the set's meta, as Vista is not a competitive staple — the TR's collector value is driven by rarity, not playability

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. The Vista TR is the first Japanese One Piece TCG TR ever produced. Even if Vista itself is not a widely played card, the historical significance and rarity of the first Japanese TR make it a meaningful collector item. Until substantially 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. With ~2 SPs per English case and four confirmed SPs competing for those slots, the expected cost to pull Miss All Sunday specifically through box openings is multiples of the card's secondary market price. SP boxes are 2-hit boxes — you give up a SEC to get one. Check current listings; SP prices for a new set typically stabilise within two weeks as opening volume increases.

If you want Blackbeard or Ace SEC

English cases are expected to hold ~8 SECs (2 copies of each of the 4 SECs), which works out to approximately 0.5–1 SEC per box. Two to three English boxes gives you a realistic (not guaranteed) shot at a specific SEC. Buying the single is still more cost-efficient unless you want the opening experience alongside it.

If you want to build competitive decks

The competitive SRs (Yamato, Boa Hancock, Sakazuki, Luffy) are obtainable within 1–2 English boxes with reasonable luck given the higher per-box SR rate, or more reliably through singles. OP16 does not require SPs or SECs for competitive play — source 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 4–7 SRs per box means consistent hits, and the alt art rare slot gives every box a realistic premium pull. Set a comfortable budget and enjoy the opening without chasing a specific SP or TR.

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 English box have a Secret Rare?

Not guaranteed per box, but English OP16 has a significantly better SEC rate than Japanese. English cases are expected to hold ~8 SECs (2 of each of the 4 SECs in the set) — roughly 0.5–1 SEC per English box on average. SP boxes are always 2-hit boxes and will not also contain a SEC. For comparison, Japanese cases hold only ~4 SECs per 12-box case.

What are the OP16 Manga Rares?

Manga Rares in OP16 are confirmed from Japanese case data: at least three were pulled from one Japanese case (Monkey D. Luffy, Koby, and one additional). No Manga Rares were pulled from the documented English 12-box case. Whether Manga Rares exist in English OP16 product is not yet confirmed from available community opening data — treat them as a Japanese-only data point for now.

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 English compare to OP15 English hit rates?

OP16 English delivers more SRs per box than OP15 English — approximately 4–7 per box vs OP15's lower count — because OP16 has only 10 SRs in the set (vs OP15's higher SR count), meaning more copies of each per case. English SEC rate is similar (~8 per case for both). English SP rate is roughly comparable (~2 per case). The notable differences: OP16 English includes the Vista Treasure Rare (not present in OP15 English in the same form), and OP16's leader packs can now yield SRs — in OP15, a leader pack signalled no other hit in that neighbourhood.

Is box searching a concern with OP16?

Yes — multiple openers flagged that OP16 cases may have been weighed or searched before reaching retail. One opener explicitly warned that "the case I think has been searched a lot." As with any sought-after set, buy sealed product from trusted sources and be cautious of loose boxes purchased at secondary market prices. Pre-order or case-level purchases from established stores reduce this risk.
