OP-17 World's Strongest Warriors Set Guide for 2026

TL;DR: OP-17 "The World's Strongest Warriors" had its US pre-release on August 21, 2026, and English release on August 28. Bandai lists 131+4 types, 6 leaders, and 1 Treasure Rare type. The 4th Anniversary set centers on Elbaph, the Straw Hat Crew, the Rocks Pirates, and the Four Emperors. On October 23, 2026, the opmetagame tier list still put Green Mihawk at the top, with Purple Enel also in S tier. OP14-020 Mihawk is banned effective October 12, 2026, so use the tracker's Mihawk ranking as a record of earlier results rather than a current recommendation. Updated October 23, 2026: prices and tier placements now come from TCGplayer and the opmetagame tier list on October 23, replacing the September tracker snapshot. Updated September 30, 2026: Bandai's September 24 notice makes OP14-020 Dracule Mihawk a Banned Card effective October 12, 2026. Read the One Piece TCG banlist and effective dates before applying the meta section to a later event.

OP-17 World's Strongest Warriors set guide: what you need to know

The short version: OP-17 is the 4th Anniversary set built around Elbaph, the Four Emperors, the Straw Hat Crew, and the Rocks Pirates. It has 131+4 card types, six leaders, and one Treasure Rare type. The US pre-release was August 21, 2026, and the English release was August 28, 2026.

For the format, OP-17 is already live. On October 23, 2026, the opmetagame tier list put Green Dracule Mihawk in S tier at a 65.0% win rate across 318 decklists, and Purple Enel in S tier with 87 decklists. Those are a dated snapshot from a fan-run database, and OP14-020 is not legal after October 11, so use the linked tournament data rather than treating the Mihawk ranking as permanent.

What Is OP-17 World's Strongest Warriors?

OP-17 is the 17th main booster set in the One Piece Card Game and the 4th Anniversary Booster Pack. The full title is "The World's Strongest Warriors," and the official product page frames the set around Elbaph, the Straw Hat Crew, the Rocks Pirates, and the Four Emperors. If you're new to the game overall, rules, colors, deck building, the One Piece TCG complete guide covers the fundamentals this set-specific guide assumes you already know.

Bandai announced the set during the Championship 25-26 season, with leader reveals rolling out through official card-reveal videos. The thematic focus is Elbaph and the Four Emperors: the official product page features Luffy, Nami, and Loki, tying the anniversary set to the giants' homeland and the franchise's top-tier powers. That's a fitting 4th Anniversary approach, and it means the featured cards skew toward the biggest names in the current story.

Six leaders are in the set, and all are now confirmed by Bandai's official card list: Edward Newgate/Whitebeard (Red), Monkey D. Luffy (Black), Shanks OP17-020OP17-020Shop on TCGplayer (Green), Kaido (Purple), Charlotte Linlin/Big Mom (Yellow), and Rocks D. Xebec (Blue). The OP-17 leaders deck potential preview is an archived reveal-season analysis, while the official card list is the authority for the locked roster.

The set is confirmed at 131+4 card types, 135 unique cards total, updated from an earlier 126+1 estimate as more of the set sheet has been revealed:

The card count is meaningfully larger than OP-16, which ran 126+1. The Treasure Rare slot is confirmed as part of OP-17's rarity structure; Bandai's product page lists the rarity categories but does not publish a pull-rate table.

Product Lineup and Pricing

OP-17 shipped in the same format as recent OPTCG sets: 12-card booster packs sold in displays of 24, with 12 displays in a case. Bandai's official MSRP is $4.99 per pack, putting a 24-pack display at roughly $119.76 before retailer adjustments.

The English release landed August 28, 2026, so this is no longer a pre-order forecast. On October 23, 2026, TCGplayer's Market Price for the English booster box was $315.56. That is a market snapshot, not a fixed price, and supply or tournament results can move it quickly.

The bigger structural change from past sets is the shrunk JP-to-EN gap. Japanese product released August 22, 2026, the US held a pre-release on August 21, and the English release followed on August 28, about a week behind Japan rather than months. That is a shorter gap than earlier main sets, although it does not guarantee stable prices or equal availability in every region.

If you want a specific card, singles are easier to budget than opening sealed product. Bandai lists one English Treasure Rare type, but the set also has several premium parallel treatments, so a sealed opening is better treated as entertainment than as a guaranteed route to a particular card. For box-vs-case quantity math now that the set is out, see our OP-17 box opening strategy guide.

The Treasure Rare Rarity Explained

Treasure Rare is a top rarity tier in One Piece TCG, sitting above Secret Rare. OP-16 handled the top rarity question through Manga Rares, while OP-17 uses a single English Treasure Rare type under the Treasure Rare label. Bandai's product page lists that type alongside the set's Secret Rares and other premium treatments.

For the English release, the Treasure Rare is the parallel printing of Edward Newgate (Whitebeard), card OP17-040. The base card is a Blue 6-cost Character with 8000 power, an On Play draw-1 effect, and a once-per-turn effect that lets you trash 1 card from hand to give a Rocks Pirates Leader +3000 power during the battle. The official card list shows the same number in both Rare and Treasure Rare printings.

Image credit: Bandai via the One Piece Card Game official English card list (OP17-040 and its parallel print).

Bandai's product page lists the rarity types but does not publish pull rates. On October 23, 2026, TCGplayer's Market Price was $1,383.43 for the OP17-079 Super Leader Alternate Art and $39.80 for the English OP17-040 Treasure Rare, so the Super Leader Parallel is the larger English chase by that measure. The Japanese product gives its Treasure Rare to a different card: Bandai's Japanese card list shows a TR print of Lucky.Roux OP17-033OP17-033Shop on TCGplayer and none for OP17-040, while the English card list has the TR print on OP17-040 and none for OP17-033.

• OP-17 Super Parallel Cards: New Manga Rare Tier Explained: Treasure Rare isn't the only premium treatment in this set. Super Leader Parallel, Super Parallel, Manga, and Conqueror's Haki Special cards add other chase paths.

New Leaders and Key Cards

Six leaders are in OP-17, built around the Elbaph and Four Emperors anniversary theme, and all six are confirmed in Bandai's current card list: Edward Newgate/Whitebeard (Red), Monkey D. Luffy (Black), Shanks (Green, OP17-020), Kaido (Purple), Charlotte Linlin/Big Mom (Yellow), and Rocks D. Xebec (Blue).

What Bandai has confirmed: the leaders are recognizable, top-power characters with updated mechanics built for the OP-17 format context. The "World's Strongest Warriors" title and the Elbaph and Four Emperors theme match the reveal pattern, six of the series' biggest names locked in as leaders, with raw power and iconic status the clear throughline.

All six leader slots are now filled and their colors confirmed, so the full roster is locked in and safe to plan around.

The OP-17 leaders preview from earlier in July is useful reveal-season background, but the official card list is the current source for confirmed characters and card text.

Beyond leaders, the cards to track are Super Rares and Secret Rares. Bandai counts 3 Secret Rare types in OP-17: the two new SEC cards, Loki OP17-119OP17-119Shop on TCGplayer (OP17-119) and Rocks D. Xebec OP17-118OP17-118Shop on TCGplayer (OP17-118), plus a Secret Rare reprint of EB04-061 that the official card list files under OP-17. Values are version-dependent and move quickly. On October 23, 2026, TCGplayer's Market Prices were $23.85 for base Loki, $42.92 for Loki's alternate art, $16.46 for base Rocks, and $34.54 for Rocks's alternate art.

Format Impact: What OP-17 Means for Standard

OP-17 is already live in English, so the pre-launch OP-16 projection is no longer the right baseline. On October 23, 2026, the opmetagame tier list put 12 leaders in S tier, 12 in A tier, Black Yamato alone in B tier, and 44 in C tier. It listed Green Mihawk first at a 65.0% win rate across 318 decklists, followed in S tier by Red/Black Sabo, Blue Rocks, Purple/Yellow Nico Robin, Black Luffy, and Purple Enel, with Yellow Big Mom also in S tier. These are dated snapshots from a fan-run database with different sample sizes, and Mihawk's Leader is banned effective October 12, so check the linked data and current legality before making a tournament call. The site's detailed post-launch breakdown is linked below.

Six new leaders arriving with OP-17 changed the competitive field, but the official product page does not announce a rotation. Confirmed legality depends on Bandai's current rules and event notices, not on an assumption that a set range will remain fixed. OP-18 The Dominance of God has an official English release date of November 20, 2026, and Bandai's product page marks it tournament legal 7 days after release. Before it, the EB-05 Extra Booster (61 numbered cards) released on October 30 and is likewise tournament legal 7 days later, and our EB-05 card list covers the ones that already made decks.

Correction (October 23, 2026): an earlier version said OP-18's date came only from retailer listings and that EB-05 joined the format on its October 30 release day. Bandai's OP-18 and EB-05 product pages give November 20 and October 30, 2026, each with "Tournament Legal after 7 days." The FAQ also gave OP-17 2 Secret Rares and 1 DON!! card type; Bandai's Japanese product page lists 3 Secret Rares and 4 DON!! cards.

The October 23 tier list shows where the field stands now: Green Mihawk still heads it despite the ban, Purple Enel sits in S tier, and Purple Kaido leads A tier with 101 decklists. That replaces the old pre-launch language about what the new leaders might do. The sample is still moving as more events are recorded, so use the tier pages and tournament results for an up-to-date view, and do not carry the Mihawk placement past its October 12 ban.

Black Yamato is no longer a safe pre-launch assumption: the October 23 tier list places it alone in B tier with 22 decklists. That does not make the deck unplayable, but it does mean the old advice to wait behind a set-agnostic Yamato shell should be treated as historical context rather than a current tier call.

For the full breakdown of what to hold, what to sell, and what preview signals to track, the OP-17 OP-16 format analysis (linked under Related Reading below) covers format positioning in depth.

Should You Buy OP-17? Collector vs. competitive

These are two different questions with different answers.

Collectors have a clear choice between opening sealed product and buying a specific parallel. The English product page confirms one Treasure Rare type, but current tracking shows that the OP17-079 Super Leader Parallel is a much larger English chase than the OP17-040 Treasure Rare. On October 23, 2026, TCGplayer's Market Price was $315.56 for the English box, $39.80 for the Treasure Rare, and $1,383.43 for the Super Leader Alternate Art. Those values are snapshots, not guarantees, so buy sealed only if you want the opening experience or sealed product itself.

Sealed boxes are still a poor way to acquire any specific rare card. One English Treasure Rare type means the odds of finding that exact parallel are not a substitute for buying the single. Opening a box for the experience can make sense; opening cases to chase one card is a much less controlled purchase.

For competitive players, the set is already fully released, so use current decklists and tournament results instead of reveal-season predictions. The OP-17 spoilers tracker (linked under Related Reading below) is now a card reference, not a countdown page. Prices often move during the first weeks after release, but the current market is already post-launch and should be checked again before buying.

If you're already running Yamato or Blackbeard, compare the current results before assuming those older shells remain the best use of your budget. If you want to pick up an OP-17 leader, prioritize a current decklist and recent event evidence over a pre-release prediction.

The OP-17 preparation guide remains useful as an archived pre-launch checklist for collectors and competitive players. For the shorter launch checklist, see OP-17 launch checklist: 6 things to do before Aug 28, which is also historical now that the set is available.

Frequently Asked Questions

When does OP-17 release in English? The English release of OP-17 The World's Strongest Warriors was August 28, 2026, after a US pre-release on August 21. Japanese product released on August 22. The official product page lists the English release date and USD $4.99 MSRP; pre-order availability is no longer relevant.

How many cards are in OP-17? Bandai lists 131+4 types in total, or 135 card types. Bandai's Japanese product page breaks that down as 10 Special Cards, 1 Treasure Rare, 6 Leaders, 3 Secret Rares, 10 Super Rares, 26 Rares, 30 Uncommons, 45 Commons, and 4 DON!! cards.

What is the Treasure Rare in OP-17? For the English release, OP17-040 is listed by Bandai as both a base Rare and a Treasure Rare parallel. It is a Blue 6-cost, 8000-power Character with an On Play draw-1 effect and a once-per-turn effect that gives a Rocks Pirates Leader +3000 power during the battle. The Treasure Rare is a premium printing, not a separate card number.

How many leaders are in OP-17? Six leaders are in OP-17, the 4th Anniversary set with an Elbaph and Four Emperors theme. Bandai's current card list confirms Edward Newgate/Whitebeard (Red), Monkey D. Luffy (Black), Shanks (Green), Kaido (Purple), Charlotte Linlin/Big Mom (Yellow), and Rocks D. Xebec (Blue).

Will OP-17 rotate any sets out of Standard? Bandai's OP-17 product page does not announce a rotation. Check the current rules and event notices for the legality of OP-16 and earlier cards, because future rotation policy is not established by this product page.

Should collectors buy OP-17 at launch or wait? The English set is already available. If you want the Treasure Rare, compare its current single price with a sealed box before buying. If you need specific competitive cards, current post-launch listings and tournament results are more useful than a launch-week buying rule.

What theme does OP-17 follow? OP-17 is the 4th Anniversary Booster Pack for the One Piece Card Game. The official product page centers the set on Elbaph, the Straw Hat Crew, the Rocks Pirates, and the Four Emperors, with Luffy, Nami, and Loki featured in the product presentation.
