OP-16 GY Law Deck Guide: Green/Yellow Decklist 2026

How we checked this: we pulled every Standard decklist from 24 Limitless Play events between September 28 and October 12 (0 GY Law lists), searched back to OP-17's release for any GY Law list (1 found), read every card's text on Limitless, and ran 100,000 simulated games per scenario to test the leader's turn-3 activation.

Updated October 13, 2026: Rebuilt for the post-ban format. The old shell used two cards that aren't Standard legal (OP01-047 and OP01-051); the list below is a real OP-17-era tournament list, with a reason for every card, simulation numbers and a matchup read against the top post-ban decks.

OP-16 GY Law deck guide: quick answer

GY Law is a fun deck, not a tournament deck, right now. The leader still works as printed: once your Characters total 5 cost or more, give him 1 DON!!, return a Character to your hand, reveal your top Life card, and if it's a Supernovas Character costing 5 or less, play it for free. The problem is the field. Xebec makes up 18.6% of post-ban lists, and its Gloriosa puts any cost 5 or less Character on the bottom of the deck, which covers every Supernova this leader can play.

On Limitless, Green/Yellow Law has 18 placings and 2 wins, and the latest are from two regionals on November 8, 2025, in the OP12 format: Justin Tyler's 12th place in San Diego and Dukaraith's 14th in Utrecht.

GY Law decklist: the only OP-17-era list

Mangu46 registered this list at Rumble league #5 | OP17 on August 20, 2026, an online event with 19 players. It finished 18th at 1-3-1: losses to Krieg, Kid and Ace, a tie with Kaido, and a bye. Every card is Standard legal and none is on the banlist.

That's 35 cards out of 50 the leader can play from Life, so your top Life card qualifies 70% of the time before you do anything. The other 15 are Borsalino, the three Laws, Shanks and the Event.

The four slots we'd change

Cut 4 Borsalino and play 4 Jewelry Bonney OP10-107 instead. OP10-107 costs 3, is a Blocker, and is a Supernova. Its On Play takes a Life card into hand and puts a cost-5 Supernova from hand on top of your Life face-up, so it works like a second Bege for Cavendish and the EB03-017 Bonney. Bouzyyy's 15th-place regional list from Toronto, on Limitless, ran four. You lose Borsalino's Life gain, but in this deck a non-Supernova on top of your Life costs you more than one extra Life card gives back.

How often the leader actually goes off

We ran Mangu46's list through 100,000 games per scenario. The model plays the cheapest set of Characters that reaches 5 total cost, keeps 1 DON!! for the leader, counts the DON!! that Cavendish and the EB03-017 Bonney set active, and uses Bege to fix a bad top Life card when it can. It assumes you haven't taken damage yet and ignores what the opponent does, so treat these as best cases.

Two things stand out. Going second, turn 2 is too early: plan the first activation for turn 3 either way. And the top Life card, not the field, is the real limit. Bege lifted it from 70% to 84%, and the OP10-107 swap took it to 93%.

Step-by-Step: the GY Law DON!! curve

These steps follow the simulation's lines, going first.

1. Turn 1, 1 DON!!: Monkey.D.Luffy OP10-111. Look at 5 and take the best Supernova, ideally Cavendish or Bege. Bartolomeo is the backup if you're holding a spare Supernova to trash.

2. Turn 2, 3 DON!!: Kid & Killer plus a 1-drop, or Bege. Kid & Killer finds another Supernova. If your top Life card is likely a miss and you hold a cost 5 or less Supernova, play Bege and swap it in face-up.

3. Turn 3, 5 DON!!: reach 5 cost, give the leader 1 DON!!, activate. Return OP10-111 Luffy so you can replay it for another search. A Cavendish from Life sets 2 DON!! active, which usually pays for the replay.

4. Turn 4, 7 DON!!: Trafalgar Law OP10-119. Put a Supernova from hand on top of your Life for next turn's reveal and give a rested DON!! to the leader.

5. Turns 5 and 6: OP16-030 Law, then Shanks at 10 DON!!. The 8-cost Law stops a rested Character refreshing and stands your green cost 5 or less Characters at end of turn. Shanks rests every opposing Character and sets 2 DON!! active, so you can still activate the leader the same turn.

GY Law matchups against the post-ban top decks

There are no GY Law match records since the ban, so this table is our reading of the card text, not results. The shares are from 587 Standard lists, September 28 to October 12.

One r/OnePieceTCG player described that Big Mom line: GY Law players are "using 5c green Bonney make a rested don stay rested on opponents turn against leaders that use the big mom package", then returning and replaying her with the leader and the 6-cost Law. Another player testing an OP-17 build said "Dragon twister also good in the meta right now", which matches Mangu46's two copies.

Our take

We like this deck, and we wouldn't register it. The engine is sound: in our simulation it goes off on turn 3 in three games out of four, and nine in ten with the OP10-107 swap. But nobody has played it into the post-ban field, the one recent list didn't win a game, and the most-played deck in the format answers every free play with Gloriosa. If you want a Supernovas deck for locals, build the list above with four OP10-107 Bonney over Borsalino, plan your first activation for turn 3, and save Shanks for the turn their Blockers would stop you. If you want to win a post-ban event, play Xebec.

Frequently Asked Questions

Is there a GY Law decklist for OP-17? One. Mangu46 registered OP10-022 Trafalgar Law at Rumble league #5 on August 20, 2026, a 19-player online event. It's the only Standard GY Law list on Limitless Play since OP-17 came out. It went 1-3-1, the win was a bye, and no GY Law list shows up in the first two post-ban weeks.

Is GY Law good after the Mihawk ban? Not as a tournament deck. It had 0 of 587 Standard lists from September 28 to October 12, and its latest results are from November 2025 regionals, the best a 12th place in San Diego. It's still Standard legal and the engine works, so it's a reasonable pick for casual play.

How often does the GY Law leader ability hit? In our 100,000-game simulation of Mangu46's list, going first, you had 5 cost on the field and a playable Supernova on top of your Life on turn 3 in 76% of games. Going second it was 85% on turn 3. Swapping 4 Borsalino for 4 OP10-107 Bonney raised those to 90% and 94%.

What does GY mean in One Piece TCG? GY is Green/Yellow, the colours of the OP10-022 Trafalgar Law leader from Royal Blood. It separates this Supernovas deck from other Law leaders, such as the OP-16 Law Character cards, which aren't leaders at all.

Is Borsalino good in GY Law? We'd cut it. Borsalino EB04-058 is a Navy card, not a Supernova, so every copy on top of your Life is a miss for the leader. Four OP10-107 Jewelry Bonney give you a Blocker that also fixes your top Life card.

Why does GY Law play Shanks? OP17-022 Shanks costs 10, has Rush, sets 2 DON!! active and rests all of your opponent's Characters. Rested Blockers can't block, which matters against Black Luffy's Giants. It isn't a Supernova, so a Shanks on top of your Life is a miss.
