OP-17 Rocks D. Xebec Deck List: Best Early Build & How to Play Blue Rocks

Rocks D. Xebec OP17-039 might be one of the strangest Leaders in One Piece Card Game OP-17: The World’s Strongest Warriors.

Blue Rocks has enormous draw power, strong board control, and one of the nastiest 10-DON!! payoff cards in the set. The catch is that much of the Rocks Pirates package has no printed Counter, so a giant hand does not automatically mean you are safe.

That tradeoff is what makes the deck interesting. Rocks wants to draw aggressively, turn otherwise awkward cards into defensive resources, slow the opponent down, and eventually rebuild an entire board with Rocks D. Xebec OP17-118.

There is no settled tournament list yet, so this is our own early testing build, based on the available card pool and several different early simulator approaches rather than copying any single creator’s list.

OP-17 Rocks D. Xebec Deck List

Our Rocks D. Xebec build keeps the deck heavily concentrated around Rocks Pirates while spreading the middle of the curve across different control tools. That matters because Rocks' Leader effect gets much worse if you start filling the deck with cards that cannot satisfy its reveal condition.

How Does Rocks D. Xebec OP17-039 Work?

Rocks is a Blue 5000-power, 5-Life Leader. When attacking, you can trash a card from your hand, reveal the top card of your deck, and draw two cards if that card's type includes Rocks Pirates. Early testers are already building very high Rocks Pirates counts specifically to keep that effect reliable.

That gives Rocks ridiculous card flow.

Streusen helps by looking at the top two cards of your deck, rearranging them, and drawing a card. Kyo replaces itself on play while also giving the deck protection against removal. If one of your Characters would be removed by an opponent's effect, Kyo can let you trash two cards instead.

The important part is understanding that Rocks is not simply trying to accumulate the biggest hand possible.

The deck is trying to turn that hand into resources.

The Counterless Cards Are the Engine

A lot of Rocks Pirates Characters are bricks in hand because they have no traditional Counter.

That looks terrible until the rest of the deck starts working.

Charlotte Linlin can turn a discarded card into +1000 power during an opponent's attack. Edward Newgate can turn one into +3000 for your Leader. Shiki can discard a Rocks Pirates card to reduce an opposing Character by 3000 power. The zero-cost Events give another source of +2000 Counter.

So the real defensive question is not:

How many Counter cards are in my hand?

It is:

How many different ways can I convert this hand into defense?

That distinction is also why Rocks looks harder to play than a normal Blue deck. One tester reached hands of 14 or more cards and still noted that the bricks can leave you vulnerable if the right defensive pieces are not established.

Stussy and Gloriosa Buy You Time

Our build keeps four Miss Buckingham Stussy because she looks like one of the archetype's best control cards.

Her On Play effect stops an opposing Character with a base cost of 6 or less from attacking through the opponent's next turn. Later, you can rest Stussy and 3 DON!! to shut down another attacker regardless of cost. Early testing has repeatedly shown her buying the turn Rocks needs to reach its bigger plays.

Gloriosa gives you another way to slow the game while developing a Blocker, bottom-decking a Character that costs 5 or less when she enters.

That gives the deck a clear early and midgame identity:

draw cards, protect your board, freeze attacks, remove manageable threats, and make the game last long enough for Rocks to take over.

Rocks D. Xebec OP17-118 Is the Payoff

The 10-cost Rocks D. Xebec OP17-118 is the reason the whole package comes together.

Rocks is a 12000-power Character that can gain +2000 Counter while in your hand if the Characters on your field are all counterless. On play, he draws a card and lets you play two differently named Rocks Pirates Characters with a combined cost of 9 or less from your hand.

That creates several strong reloads:

Rocks → Charlotte Linlin + Kaido

Linlin forces the opponent to choose between giving you two cards or losing two from their own hand, while Kaido gives you a 6000-power Blocker and power reduction.

Rocks → Edward Newgate + Stussy

You add Newgate's defensive engine and card draw while Stussy immediately shuts down an attacker.

Those are the turns that can completely flip a game.

Your opponent may spend several turns clearing your board, only for one 10-cost Rocks to put three large bodies back into play.

Why We Are Testing Captain John

The middle of the deck is where Rocks still looks least solved.

We are testing two Captain John rather than maxing either Captain John or Ganswei.

Captain John can rest himself to draw a card and trash a card, while forcing the opponent to attack him instead of your other cards while he remains rested. One tester initially left him out, then came back around to considering a small package because of his value against aggressive and unblockable strategies.

Ganswei still gets two slots because making Rocks a 6000-power Leader can be excellent against decks built around repeated 5000-power attacks, but multiple testers have questioned whether four copies are necessary.

That is exactly the kind of ratio I expect to change once OP-17 gets real tournament data.

Is Rocks D. Xebec One of the Best OP-17 Leaders?

It is too early to say, but the ceiling looks very real.

Early simulator testing has shown Rocks surviving removal-heavy games, rebuilding with OP17-118, and creating enormous late-game boards. At the same time, testers have consistently identified aggressive matchups as a potential weakness, because repeated early attacks can force Rocks to spend its unconventional defensive resources before its engine is fully established.

That makes the game plan pretty clear:

Cycle aggressively with Rocks, use Stussy and Gloriosa to slow the board, turn counterless cards into defensive value through Linlin, Newgate, Shiki and the Events, then reach 10 DON!! and let Rocks D. Xebec OP17-118 rebuild the crew.

This is not a deck I would call solved yet.

But it may be one of OP-17's most rewarding decks to solve.
