In 60 Seconds
- The plan
- the discount every turn you have a Law: the 6000 Blocker Law (P-093) on your 2nd turn, Rosinante & Law on your 3rd, and with no more DON!! than them each gives you a DON!! back. Then Sakazuki, a wall of Blockers, and your Leader swinging every turn. Once a turn, when a Law would be K.O.'d, your top Life card can go to your hand instead.
- The list
- the Laws (the 6000 Blocker Law, Rosinante & Law and the vanilla Law, 4 each), Sakazuki and Borsalino, the searchers Koby, Marineford and Sugar, and counter Events. It's in The Deck.

- Keep or redraw
- keep the 6000 Blocker Law: nothing in the list searches for it. Without it, mulligan.
- The matchups that matter
- Buggy: players won 46%; go 1st, and its bottom-of-the-deck removal gets past the Law save.
- Nico Robin: 52%.
- Xebec: 52%; go 2nd.
- Top 3 mistakes
- Keeping hands without the 6000 Blocker Law.
- Missing the curve (going 1st, 78% won with it, 38% without).
- Going 1st against Xebec.
Rosinante in one line: players win 52% of their EB05 games with Rosinante (776), and the deck is built on one curve: your Leader's DON!! -1 makes a Trafalgar Law cost 2 less, so the 6000 Blocker Law lands on your 2nd turn and the 8000 Blocker Rosinante & Law on your 3rd.
What Is Rosinante?
- The Law discount: DON!! -1, and your next Trafalgar Law that costs 4 or more costs 2 less.
- Parity: with no more DON!! than them, the 6000 Blocker Law and Rosinante & Law give you a DON!! back.
- Weak spots: Sabo (33%), Shirahoshi (38%), and removal that isn't a K.O.
- The Law save: once a turn, when one of your Trafalgar Laws would be K.O.'d, put your top Life card in your hand instead. Rosinante & Law counts as a Law.
- The DON!! you return comes back: on curve, the discount brings you level with them, so the Law's On Play gives the DON!! right back. Strong players had it pay on 95-97% of plays.
- You start at 4 Life, one fewer than most of the field.
The Deck
- The wall: the 6000 Blocker Law, Rosinante & Law (an 8000 Blocker) and Borsalino.
- The engine: Koby, Marineford and Sugar dig; You Need Me, Don't You?! draws 3.
- Sakazuki is your big play: -6000 on one of theirs, and 2 DON!! a turn.
The list
| Card | Copies | Its job |
|---|---|---|
| You Need Me, Don't You?! (EB05-040) | 4 | Return a DON!!: draw 3, trash 1; +2000 counter |
| Divine Departure (OP13-076) | 1 | -8000 on one of theirs; +3000 counter |
| Mamaragan (OP15-078) | 4 | Draw 1, rest a 5000-or-less; +1000 counter |
| Sugar (OP10-065) | 4 | Look at 5 for a Donquixote Pirates card |
| I Love You!! (OP12-115) | 4 | +2000; at 2 Life or less, a Law back from your trash |
| Koby (OP16-064) | 3 | Look at 5 for a Navy card |
| Marineford (OP16-078) | 4 | Look at 5 for a Navy card; DON!! -1: draw 1, trash 1 |
| NoroNoro Beam Sword (OP07-076) | 1 | +2000 and rest one of theirs |
| Baby 5 (OP12-112) | 1 | A 2000 counter; Trigger: draw 2 |
| Trafalgar Law (P-088) | 4 | A 2000 counter, nothing else |
| Trafalgar Law (P-093) | 4 | 6000 Blocker; a DON!! back at parity |
| Trafalgar Law (ST10-010) | 1 | 5000 Blocker; they trash 2 if they hold 7+ |
| Borsalino (EB04-058) | 4 | 6000 Blocker; adds a Life card at 2 Life or less |
| Rosinante & Law (EB04-038) | 4 | 8000 Blocker; draw 1 and an active DON!! at parity |
| Black Rope Dragon Twister (EB04-059) | 2 | K.O. two of theirs when you have fewer Characters |
| Sakazuki (OP16-065) | 4 | 8000; -6000 on one of theirs; rest 1 DON!!: add 2 |
| Trafalgar Law (EB03-062) | 1 | 6000 Rush; trash it: +1 Life and play a Law |
Mulligans
- Keep the 6000 Blocker Law: in our same-hand test those hands won 54% kept, 33% sent back.
- No 6000 Blocker Law: mulligan (28% kept, 37% sent back), even with Rosinante & Law.
- The vanilla Law (P-088) doesn't replace it: it's a counter.
THE 6000 BLOCKER LAW (P-093) = KEEP. NO 6000 BLOCKER LAW = MULLIGAN.
| The hand | Won kept | Won sent back |
|---|---|---|
| The 6000 Blocker Law | 54% | 33% |
| No 6000 Blocker Law | 28% | 37% |
| ...but Rosinante & Law | 28% | 39% |
- Lists with the 1-cost Rosinante (OP12-108) can lean keep without the Law: it digs for one.
- Keep: Rosinante & Law, I Love You!!, I Love You!!, Marineford, the 6000 Blocker Law. Mulligan: Borsalino, You Need Me, Don't You?!, Sugar, two Marinefords (no Law).
Turn Order: Usually 1st
- Players win 54% going 1st and 48% going 2nd.
- Go 1st against Buggy and Kaido.
- Go 2nd against Xebec (players 59% going 2nd, 47% going 1st). The rest is in the table.
The Game Plan, Turn by Turn
- A searcher on your 1st turn, the 6000 Blocker Law on your 2nd, Rosinante & Law on your 3rd.
- Then Sakazuki around your 4th or 5th turn, and your Leader attacks every turn.
- The kill comes on your 6th to 8th turn, most often with Rosinante & Law.

| Your turn | Going 1st | Going 2nd |
|---|---|---|
| 1st | Koby, Marineford, the 1-cost Rosinante or Sugar | Marineford, Koby or the 1-cost Rosinante |
| 2nd | Discount + the 6000 Blocker Law | Discount + the 6000 Blocker Law |
| 3rd | Discount + Rosinante & Law | Discount + Rosinante & Law |
| 4th | Rosinante & Law or Sakazuki | Sakazuki |
| 5th+ | Sakazuki, Borsalino (at 2 Life or less), Rosinante & Law | The same |
- A 1-cost goes first: the discount can return a DON!! you already rested, so play Marineford, then DON!! -1, then the Law for your last 2.
- Why the curve: going 1st, strong players who made both plays won 78% (38% without); going 2nd, 65% (20% without).
Fundamentals: The Law Discount and the Law Save
- Use the discount on every turn you have a Law to play.
- Save Rosinante & Law; save the 6000 Blocker Law at 3-4 Life only; let the 5000 Blocker Law go.
- Block with your Laws; your Leader attacks every turn.

SAVE ROSINANTE & LAW. SAVE THE 6000 BLOCKER LAW AT 3-4 LIFE, NOT AT 1-2.
| The Law being K.O.'d | Strong players saved it at 3-4 Life | At 1-2 Life |
|---|---|---|
| Rosinante & Law | 31 of 36 | 35 of 50 |
| The 6000 Blocker Law | 31 of 40 | 10 of 43 |
| The 5000 Blocker Law | 6 of 13 | 4 of 51 |

- The save stops K.O.s only: bottom-of-the-deck removal (Buggy's 10-cost Buggy, Xebec's Gloriosa) gets past it.
- Block a lot: strong players blocked 27% of the attacks on their Leader; Rosinante & Law lost only 19 of its 332 blocks.
- From 3 Life the counters come out: the vanilla Law (P-088) first, then I Love You!!, which at 2 Life or less also brings a Law back.
| Your Life | Countered (unblocked) | Got through |
|---|---|---|
| 4 | 14% | 68% |
| 3 | 42% | 42% |
| 2 | 60% | 30% |
| 1 | 67% | 23% |
- Face with your Leader: 65% of strong players' attacks went at the opponent's Leader. The kill: your 6th to 8th turn (62 of 90 wins).

Players: EB05 ladder games, every bounty level, with farmed games removed (the same two accounts playing each other 8+ times, one side winning 85%+); '-' under 30 games, or under 15 a side for the split. Our Pro AI: 300 games per matchup for the seven most played decks, 100 for the rest.
Buggy (OP09-042)
- Go 1st (53% vs 39%) and go face (66% of strong players' attacks went at Buggy's Leader).
- The 10-cost Buggy and Gravity Blade bottom-deck your Characters, Rosinante & Law included: the Law save doesn't stop it.
Nico Robin (EB05-010)
Practice vs Nico Robin · Hard AI
- Lean 1st and go face: her Leader adds a Life card when her Wisdom Characters are K.O.'d.
- Her attacks come often but small: only 23% took a Life card. Megalo K.O.s a rested Rosinante & Law, but the save can keep it.
Xebec (OP17-039)
- Go 2nd (59% vs 47%); Xebec's own data is even, so this is players' call.
- Gloriosa bottom-decks a cost 5 or less (your 4-cost Laws, Borsalino): the save doesn't stop it.
Law, Kaido and the problem matchups
- Law: lean 1st, and block (34% of its attacks were blocked, the most here).
- Kaido: go 1st (68% vs 41%) and go face; its 10-cost Kaido K.O.s a cost 6 or less (the save covers Rosinante & Law).
- Sabo (33%): Loki K.O.s total cost 4, a 4-cost Law or your 1-costs; the save keeps one Law.
- Shirahoshi (38%): it goes for your board; Shanks rests everything.
- Luffy & Ace (our Pro AI 19%): it swings about twice a turn at your Leader and almost never at your Characters (7%): keep counters for your Leader.
The Mistakes That Cost Games
- Keeping hands without the 6000 Blocker Law.
- Missing the curve.
- Going 1st against Xebec.
| The spot | Strong players | What wins |
|---|---|---|
| Keep a hand without the 6000 Blocker Law | 41% | Send it back: 28% kept, 37% sent back |
| Both curve plays (going 1st) | 46 of 104 games | 78% won with both, 38% without |
| Against Xebec, go 1st (when choosing) | 8 of 13 | Go 2nd: 59% vs 47% |
Cheat Sheet
- The discount: DON!! -1, next Law 2 less: the 6000 Blocker Law on turn 2, Rosinante & Law on turn 3. The DON!! comes back at parity.
- Mulligan: keep the 6000 Blocker Law; without it, send it back.
- Turn order: 1st against Buggy and Kaido; 2nd against Xebec.
- The Law save: Rosinante & Law always; the 6000 Blocker Law at 3-4 Life; never the 5000 Blocker Law. K.O.s only.
- Defense: block with your Laws; counter from 3 Life, the vanilla Law first. Attack: your Leader every turn.
