Rocks D. Xebec strategy

Blue Rocks D. Xebec (OP17-039) is a 5-life, 5000, Slash Leader. When he attacks he may trash one card, then reveal the top of the deck: if that card’s type includes Rocks Pirates, you draw two. The 169-list OP17 core is almost all Rocks Pirates, so that attack trigger is the engine. The list is also Slash, which means Mihawk is the awkward seat.

New Realm still puts Rocks in Tier 1 with Mihawk and Sabo. Limitless pairings in the same window have him at 33.6% versus Mihawk in 149 games. This page is the curve for the seats he actually wins, and the keep/cut sheet for the 50-card average.

How the leader works

OP17-039 · 5 life · 5000 · Slash
  • Attack every turn you can pay the trash. The reveal is how you find the next on-curve Rocks Pirates card.
  • Sitting on the Leader to “save” a trash usually feels worse than just attacking, especially when the top-deck is your only search.
  • Cards that are not Rocks Pirates miss the draw. Buckin (OP08-051) is typed Former Rocks Pirates, so she does not count.
  • Mihawk gains +1000 if the opposing Leader is Slash, so he is a 6000-power Leader for free in that pairing. That is the 66.4% Mihawk record, not a play mistake on your side.

The current 50-card core

Averaged from 169 OP17 lists on this site

This is a tight type deck. OPDeckGuide’s Rocks guide is the public curve this page follows. Tech space is small because the 4-ofs already fill the even costs.

  • Play 4: Kyo (OP17-045), Miss Buckingham Stussy (OP17-054), Gloriosa (OP17-046), Charlotte Linlin (OP17-049), Edward Newgate (OP17-040), Shiki (OP17-048), Rocks D. Xebec (OP17-118), Rocks Pirates (OP17-056), and There’s No Authority in the World That Lasts Forever!!! (OP17-055).
  • Play 3: Streusen (OP17-050), Don Marlon (OP17-052), Captain John (OP17-044), and Kaido (OP17-042).
  • Play 2: Buckin.

The curve

Even line · odd line · 10-cost Xebec
  • OPDeckGuide splits the deck into two on-curve lines. Going second is the preferred seat so the 7-cost Shiki and 10-cost Xebec turns land on time. Shiki is printed at 7, not 8, so on 8 DON!! going second you play him and still have 1 DON!! up.
  • Even line: 2 DON!! Kyo (draw 1, protect a removal). 4 DON!! Captain John (forces attacks at him while rested) or Gloriosa (Blocker, bottom a cost-5-or-less). 6 DON!! Newgate (draw 1; trash to give the Leader +3000 in battle). 7–8 DON!! Shiki (Rush: Character, trash a Rocks Pirates card for −3000).
  • Odd line: 1 DON!! Streusen (reorder 2, draw 1), then Kyo, then Linlin on 5 DON!! (opponent draws 2 or trashes 2), then Shiki. Play Linlin if the board is empty. Saving her for Shiki usually is not worth it.
  • 10 DON!!, Character Xebec: on play he draws 1 and plays up to two Rocks Pirates with different names and a total cost of 9 or less. That is the double-deploy the deck loves. Keep one Xebec in the late hand. Two can brick if Shiki never hit.
  • The two 4-of 0-cost events set up or protect that turn: Rocks Pirates bounces a cost-6-or-less (rest 5 DON!!); There’s No Authority gives the Leader Unblockable (rest 1 DON!!).
  • Going first, keep Kyo plus John, or Streusen plus Linlin. Accept that Xebec is a turn later. A hand of Shiki + Xebec + events with no 2-cost is a mulligan.

Mulligan

What to keep · what to send back
  • Keep (second): Kyo + (Captain John, Gloriosa, or Linlin) + (Newgate or Shiki). That is a complete even or odd line.
  • Keep (first): Streusen or Kyo, plus one 4- or 5-cost. Shiki in this seat is fine if the cheap card is there.
  • Send back: double Xebec, event-only hands, and Kaido + Xebec with no 2-cost.
  • Buckin as the only 1-cost is also a send-back. She is a 2-of, not the Kyo replacement, and she does not hit the Leader reveal.

Tech cards

Flex from the 169-list average
  • Buckin (2): extra 1-cost. She is not Rocks Pirates type. Keep Kyo at 4 instead of adding a third copy.
  • Don Marlon (3): 3-cost that returns a 0-cost blue Event from trash. Nice if you burn Rocks Pirates / There’s No Authority on sight.
  • Kaido (3): 4-cost Blocker that −3000s if you reveal 3 Rocks Pirates from hand. He is the 4-drop backup, not an 8-cost.
  • Stussy / Gloriosa (4 each): these look like tech and are not. Stussy stops a cost-6-or-less from attacking; Gloriosa bottoms a 5-or-less. Cutting them for “answers” is how the type density dies.
  • OPDeckGuide’s warning is the constraint: there is little tech space. If you add a card that is not Rocks Pirates, you miss draws off the Leader. Stick to cards that already show up on a hosted 50-card list.

Win rates and matchups

Limitless pairings · then the public guide
  • Limitless constructed pairings from 28 August 2026, 16 events, 832 games, 8-game cutoff. Same sample as the Mihawk pairing table.
  • Rocks vs Mihawk, 33.6% in 149 games (50–99). Mihawk is 66.4% in the pairing. Slash Leader plus a recycled-DON!! rest lock is the worst matchup in the sample.
  • New Realm still puts Rocks in Tier 1 with Mihawk and Sabo. The deck wins the seats Mihawk is not. A public Top 32 Utrecht Finals graphic counted only 1 Xebec. That is conversion, not proof the deck is unplayable.
  • Feels good: Sabo, Ace, Linlin, Shanks, Luffy & Ace, Enel (OPDeckGuide’s qualitative strip, not a pairing table).
  • Feels bad: Mihawk, Kaido, Black Luffy.
  • If the room is Mihawk-heavy, you are the underdog every round you pair it. If the room is Sabo / Ace / Emperor midrange, Rocks is the deck New Realm is ranking in Tier 1. Cutting Rocks Pirates cards to “tech Mihawk” usually just loses the other pairings too.
