How to Build a One Piece Deck

The deck construction rules

A One Piece deck has three parts. You choose the Leader and the 50-card main deck, and the 10-card DON!! deck works the same for everyone. These rules come from Bandai's Comprehensive Rules as of September 2026.

The card number is the code in the bottom right corner, such as OP01-016. A Parallel or alternate art has the same number as the card it copies, so four of the base card and one alternate art is five copies and not a legal deck. Our guide to reading a One Piece card shows where the number, cost and counter sit, and Parallel vs. alternate art explains the printings.

Tournament legality adds two things on top of these rules. Bandai publishes banned and restricted lists that change over time, and since April 2026 the Standard format rotates by the block number printed on each card. Check Bandai's current announcements before a tournament.

A build order for a first deck

Start with the Leader, because it sets your colors and your Life, and its effect usually tells you what the other 50 cards should do. Read that effect carefully before you choose anything else.

1. Pick a Leader. Choose one whose effect you understand and whose colors match the cards you already own.
2. Fill the low end first. Characters that cost 1 or 2 give you something to play on the early turns, when you have little DON!! to pay with.
3. Add your Characters. Most of the 50 are usually Characters, because they are what attack, block and carry effects. Check each one's color against the Leader.
4. Count counters. A Character's counter value lets you trash it from your hand to add power to a defender. With few counters in hand, most attacks on your Leader get through, so check how many 1000 and 2000 counters the deck has.
5. Add Events and Stages. Events are one-shot effects, and some double as counters. Stages stay in play. Take only as many as the plan needs.
6. Add a few expensive cards. You gain 2 DON!! a turn, so a card that costs 6 or more usually can't be played until your third or fourth turn. A handful is plenty for a first deck.
7. Cut to exactly 50 and four copies. Run four of the cards you want to see every game and fewer of the situational ones.

A frequent mistake in a first deck is too many expensive cards. If your opening hand is full of cards you can't pay for, you spend the early turns doing nothing while your opponent attacks, so the spread of costs often matters more than the strength of any one card.

Building in the Deck Lab

TurnZero HQ's One Piece deck builder is the Deck Lab, and it works like the Deck Lab for the other supported games. You build the list and the server measures it, so the numbers you see while editing are the numbers you get after you save.

1. Start a new One Piece deck. Give it a name, and choose the Standard format. You can also paste a decklist in the "4xOP01-016" style that most simulators and deck sites share, with the Leader first.
2. Optionally pick a template. Balanced midrange is the recommended one, Aggro and Control are the other two, and Custom starts empty. Each one is a set of target counts, such as Characters, Events and low-cost cards, with a band around each target.
3. Add cards from search. The Leader goes in its own section and everything else goes in the main deck.
4. Watch the header. It shows the deck's card count against 50, its rules (Legal, or N to fix) and the chance of a good opening hand.
5. Save. Edits stay in a draft on your device until you do.

On a wide screen the build column and the readings sit side by side. On a phone the Lab splits into tabs for the deck, its cards and its stats. Formats, publishing, the decklist and delete are in the overflow menu.

What the Deck Lab checks

The rules check turns the construction rules into a list of things to fix. Each one names the card or the count that is wrong.

Beside the rules check are five lenses, which describe the deck's shape. A lens is not a rule: a warning in one shows up under "Worth fixing" but doesn't make the deck illegal.

The opening hand lens is a probability calculated from the deck as you have built it. Use it to compare two versions of a list; it can't tell you what you will draw in any one game. The Deck Lab does not tell you which cards to play or rank decks against each other. It says whether the list follows the rules and what its shape is.

Owned cards and publishing

One more lens compares the deck to the cards you have scanned or added to your One Piece collection: how many copies you own, how many you are missing and what the deck is worth. It shows how many cards you still need before you can play the list in person. The copy count follows the same rule as the deck check, so a card counts by its card number and an alternate art you own fills a slot for the base card.

When a deck is ready, you can publish it from the overflow menu. Publishing is opt-in, and the deck goes to the One Piece decks page and never anywhere else. From the same menu you can copy the decklist as text to share with a playgroup or paste into another tool. Once you have a deck that runs, how to play the One Piece Card Game covers the turn it plays, and the life tracker keeps score. If you start from a pile of cards, the card scanner is the fastest way to get them into the collection lens.
