OP-16 The Time of Battle is the next major One Piece Card Game release after OP-15, and it has the exact ingredients collectors usually chase: a Marineford / Summit War theme, six new Leaders, Secret Rares for Ace and Blackbeard, and a Super Parallel lineup centered on the three Admirals.
The Japanese set, 決戦の刻 / Kessen no Toki, releases in Japan on May 30, 2026. The English version follows on June 12, 2026 under the name The Time of Battle. This guide tracks what is confirmed, what is still estimated, and how to think about sealed boxes before release.

OP-16 Set Overview
OP-16 returns to the war that defined One Piece for a generation of fans: Impel Down into Marineford. The official Japanese product page frames it as the return of a world-shaking decisive battle, with many characters from that war appearing across the set.
That matters commercially. Marineford is not a small side arc. It includes Luffy trying to save Ace, Whitebeard's final stand, the Navy's full force, the Warlords, Blackbeard's arrival, and the emotional pivot that shaped the post-timeskip story. For a trading card set, that gives OP-16 a broader collector audience than a normal mechanical release.
| Rarity | Count |
|---|---|
| Leader | 6 |
| Secret Rare | 2 |
| Super Rare | 10 |
| Rare | 26 |
| Uncommon | 30 |
| Common | 45 |
| Special Card | 6 |
| Treasure Rare | 1 |
| DON!! Card | 1 |
This is the part to watch: OP-16 has both collector demand and player relevance. Sets with only one of those can fade after launch. Sets with both tend to hold attention longer.
New Leaders in OP-16
The official page highlights six new Leaders. Each one maps to a faction or storyline from the Summit War period.
| Leader | Color | Theme / Deck Direction |
|---|---|---|
| Portgas.D.Ace | Red | Whitebeard Pirates, aggressive pressure, fast attacks |
| Monkey.D.Luffy | Green / Blue | Impel Down, resource acceleration, fast development |
| Buggy | Blue | Impel Down / Buggy Pirates, board swarming and tempo |
| Sengoku | Purple | Navy / Admirals, high-cost power turns |
| Yamato | Black | Wano, trash recursion and rush pressure |
| Marshall.D.Teach | Black / Yellow | Blackbeard Pirates, defensive control and attack redirection |
Best collector Leaders
Ace and Blackbeard should be the broadest collector targets because they sit at the emotional center of Marineford. Luffy is always liquid, even when the specific card is not the most competitive. Yamato has a strong standalone collector base, and Sengoku may become more attractive if the Admiral package performs in tournaments.
Best player Leaders to watch
Sengoku is the most interesting if the Admiral engine gets enough consistency. Luffy has the cleanest early appeal because Impel Down resource acceleration is easy to understand. Blackbeard is the wild card: defensive redirection effects can be format-shaping if the support cards line up.
Best OP-16 Chase Cards to Watch
Because OP-16 is not fully launched yet, this section focuses on confirmed high-attention slots rather than pretending day-one prices are settled.
Official Super Parallel Preview
Official SEC Preview
1. Kuzan Super Parallel
Kuzan is one of the three Admiral Super Parallels currently drawing the most attention. The Marineford theme gives him stronger narrative value than a random Navy support card, and purple Navy support could keep the card relevant beyond pure collecting.
2. Sakazuki Super Parallel
Sakazuki is likely to be the most emotionally charged Admiral chase because of his Marineford role. That can cut both ways: some collectors love the villain profile; others prefer Ace, Whitebeard, or Luffy. Either way, Sakazuki should be one of the most watched cards in the set.
3. Borsalino Super Parallel
Borsalino completes the three-Admiral chase group. If OP-16 box openings show the Admiral Super Parallel slot is genuinely hard to hit, collectors may try to complete all three rather than buying just one.
4. Portgas.D.Ace Secret Rare
Ace has the cleanest collector demand in the set. If the Secret Rare or parallel treatment looks strong, Ace can be one of the safest long-term singles because his value does not depend entirely on the meta.
5. Marshall.D.Teach Secret Rare
Blackbeard is a long-term franchise villain. If his OP-16 card is playable, the Secret Rare can carry both player and collector demand. That combination usually creates better liquidity than art-only chase cards.
6. Treasure Rare
The official Japanese product page lists one Treasure Rare. Treat this as a high-variance collector slot until enough openings confirm exact availability and market pricing.
7. Leader Parallels
Leader parallels are usually liquid because they appeal to players and collectors. Ace, Luffy, Blackbeard, and Yamato should be the first four to monitor.
OP-16 Pull Rates and Box Hit Rates
Important disclaimer: Bandai does not publish official pull rates. The rates below are estimates based on recent Japanese One Piece Card Game booster box and case behavior. Use them for planning, not as a guarantee.
| Pull / Slot | Estimated Rate | Plain-English Meaning |
|---|---|---|
| SR | Usually multiple per box | Baseline hit floor |
| SEC | Around 1 in 4-6 boxes | Not guaranteed in one box |
| Leader Parallel | Around 1-2 per case | Strong chase for players |
| Special Card | Around 1 per case range | Character choice matters heavily |
| Treasure Rare | Very scarce | Confirm exact market data after launch |
| Super Parallel / Manga-style chase | Case-level to multi-case-level | Do not open boxes expecting this |
The right way to think about OP-16 is not "how many boxes until I hit the top card?" It is:
- One box gives you the opening experience and a chance at upside.
- A sealed case gives you better distribution across high-rarity slots.
- A single chase card is usually cheaper to buy directly than to chase through random boxes.

Should You Buy Japanese OP-16 or Wait for English?
This is the cleanest split.
| Buyer Type | Better Choice | Why |
|---|---|---|
| Japanese card collectors | Japanese OP-16 | First release, original language, Japanese print quality |
| English-language players | English OP-16 | Tournament readability and local demand |
| Sealed investors | Depends on allocation | English can spike if allocation is tight; Japanese has earlier market discovery |
| Singles buyers | Wait 2-4 weeks after launch | Early prices are usually unstable |
| Marineford collectors | Japanese early + singles later | One box for experience, then target the exact Ace/Admiral cards |
Japanese boxes arrive first. That means Japan will set the early market narrative: which cards are actually hard to pull, which Leaders are playable, and which chase singles hold after the first wave of openings.
English boxes matter for a different reason. English demand is driven by local play, sealed allocation, and restock visibility. OP-09 and OP-13 showed that English One Piece sealed product can move very differently from Japanese sealed product when supply tightens.
For the deeper version of this buying decision, use the OP-15 version as a framework: OP-15 Japanese vs English: Which Version Should You Buy?.
Box vs Singles: The Smart Buying Plan
If you want the top chase card, do not pretend sealed boxes are the cheapest path. They usually are not.
Buy a box if:
- You want the opening experience.
- You collect sealed Japanese One Piece boxes.
- You are comfortable with variance.
- You want first access before English release.
Buy singles if:
- You only want Ace, Blackbeard, or one specific Admiral.
- You care about grading candidates.
- You do not want duplicate bulk.
- You can wait for the first price correction.
Best practical plan
- Buy one Japanese box or a small sealed quantity for the experience.
- Watch the first two weeks of Japanese openings.
- Buy specific singles after supply appears.
- Re-check English sealed allocation before June 12.
That gives you exposure without turning the whole purchase into a lottery ticket.
Price Outlook Before Release
OP-16 should launch with strong attention because Marineford is a major arc and the card pool has several obvious collector anchors. The risk is that early prices can be emotionally inflated before enough supply reaches the market.
Cards most likely to hold better:
- Ace high-rarity cards
- Blackbeard high-rarity cards
- Admiral Super Parallels, especially if the full trio becomes a display target
- Strong Leader Parallels with both player and collector demand
Cards most likely to correct:
- Mid-tier parallels with no meta role
- Non-iconic characters that spike only because they are new
- Cards with wide day-one pricing and low buylist support
For sealed Japanese boxes, watch the restock pattern. If boxes soften toward MSRP after launch, singles may become the better value. If OP-16 allocation is tight and the Admiral chases prove extremely scarce, sealed boxes can hold a stronger premium.
