A compact OP17 guide for Rocks.D.Xebec, including its leader effect, the updated decklist, your
best curve, the odd curve, key 10 DON!! plays, matchup notes, defensive transformation lines,
strengths, weaknesses, and a short conclusion on the deck’s current direction.
Going second is your best start. The curve shown is just an example, because Xebec’s lines can
change a lot depending on the matchup and your hand texture.
2 DON!!
Kyo is the cleanest even-curve opener because playing it immediately draws 1, so your hand does not lose momentum while you develop the board. The important part is what happens after that: as long as Kyo stays in play, whenever one of your Characters would be removed by an opponent’s effect, you can trash 2 cards from hand instead. That means it is not just a tempo starter, it is also a protection piece that helps your key bodies survive and lets you keep your even curve online into Captain John, Edward.Newgate, and beyond.
4 DON!!
Captain John is your four-DON!! stabilizer because once it is rested, the opponent can no longer attack your other cards freely and has to go through it first. That makes it excellent for protecting the rest of your board and forcing awkward combat patterns. On top of that, it can rest itself to draw 1 and trash 1, which fixes weak cards in hand and prepares stronger follow-up turns. In practice, this card is doing two jobs at once: it locks combat around itself and smooths your resources for the bigger turns that come next.
6 DON!!
Edward.Newgate is the even-curve pivot because it gives you a strong body while turning the rest of your hand into real combat value. In this deck, that matters on both sides of the turn: offensively, it helps you pressure the opponent with stronger attacks and forces more demanding responses; defensively, it lets you preserve your board and life total by making your exchanges much harder to win cleanly. The card is strong here because it does not ask you to choose between defense and pressure, it gives you both at the same time.
8 DON!!
Shiki is your high-end even-curve payoff when you want a large threat that changes combat math immediately. It turns otherwise weak cards in hand into a meaningful swing, which makes the turn powerful offensively because you can push damage while keeping pressure on the board. But the role of the card does not stop there: since the effect also functions during the opponent’s attack, Shiki can protect you on the following turn cycle as well. That is why this play is so important in the curve: it gives you a big body, stronger attacks, and a real defensive follow-up if the game keeps going.
Odd Curve
The curve shown is just an example. Xebec’s plays vary greatly depending on the matchup.
1 DON!!
Streusen is your cleanest odd-curve opener because it looks at the top 2 cards, lets you reorder them or send them to the bottom, then draws 1. That means it improves hand quality immediately while also setting up the top of your deck so your next turns and leader effect stay consistent.
3 DON!!
Kyo is the bridge card of the odd curve. On play it replaces itself with a draw, and once it is on board it forces the opponent to respect your protection line because any effect removal on one of your characters can be answered by trashing 2 from hand instead. It is what lets you keep developing without folding to effect-based interaction.
5 DON!!
Charlotte Linlin is your five-DON!! stabilizer when you want a real body on board without giving up defensive texture. In this shell, it helps convert awkward cards in hand into extra counter value, so the turn is not just offensive pressure: it also makes your following exchanges safer and keeps the leader engine live longer.
7 DON!!
Shiki is the odd-curve payoff because it gives you a large body while turning weak cards in hand into a big swing in combat. The important part is that the effect is not only offensive: it also works during the opponent’s attack, so Shiki can turn a 7-DON!! turn into both pressure on your turn and protection on theirs.
10 DON!! Plays
10 DON!! payoff
Rocks.D.Xebec OP17-118 turns your 10-DON!! turn into a flexible double-deploy. Pick the pair that best matches the board state and matchup.
Xebec looks like one of the more complete decks in the current field. It pressures slower
leaders, keeps cards flowing, and has enough high-end tempo to stay favored across a large
part of the matchup spread.

Conclusion
The leader ability is one of the strongest of the set and leads you to always have cards in hand.
Aggressive decks like Black Luffy OP17 could end up struggling because of it.
The "Rocks Pirates" limitation doesn't seem like a problem, but it allows little margin for deck
building or for some tech.
