One Piece Card Game · Deck Builder

Build a deck, get told what's wrong with it

Pick a leader, then load what wins with it or search and build your own. Every number on this page is counted from real tournament decklists.

How these numbers are worked out

When this page says meta runs 4, that is a measured share of winning lists with your leader that actually run four copies. It is not a heuristic and not a guess.

Inclusion rates are computed per leader, across every ingested decklist piloting it. A leader needs at least recorded decks before it gets meta recommendations — below that the signal is noise. That bar gates the advice, not the card: every leader in the game is in the picker, and one under the bar still gets color-legal search, deck stats and mechanical matches, and is told plainly that it has no meta data rather than being shown a rate of zero.

Counter targets compare your deck to the measured average for your leader, not to a rule of thumb. Nothing here is simulated — no card effects are executed.

Nothing on this page is simulated — no card effects are executed. A leader with fewer than recorded decks is told it has no meta data, rather than being given a rate of zero.

Card images, rarity codes and what a printing is

printings are rendered from docs/art/ next to this file at Bandai's native resolution (600px preview, 868px where Bandai publishes it larger; 300px thumbnail), never upscaled. Open the page from the repo and you get those. Published, the relative files are blocked, so base cards fall back to art embedded in the page and alternate printings show as unavailable rather than showing you the wrong picture. A card with no image at all is drawn — the back you see is CSS, not a scan, and it is not a broken image.

Rarity codes come from print-level data where it exists. A parallel marked inherited is showing its base card's rarity because no print-level classification was found for it — that is stated rather than guessed.

Which art you pick is cosmetic. Deck exports always use the base card number, which is what the sim expects, and the four-copy rule counts card numbers rather than printings.
