Deck builder
Choose your Leader and build the 50-card deck around it. Gradely flags cards outside the Leader's colours or over four per card number, and shows the numbers One Piece players tune by: cost curve, power spread, counter values and how many triggers you are running.


The Leader has its own slot and sets the colours for the rest of the deck. Any card with a colour outside your Leader's colours is flagged, including for two-colour Leaders.
See how many +1000 and +2000 counters you run, how many cards carry a trigger, and the Leader's life, which is what decides how your deck survives the late game.
Plot your Characters, Events and Stages by cost and by power, so you can tell whether the deck actually uses its DON!! each turn.
The four-copy limit is counted by card number, so mixing a parallel or alternate art with the regular print still counts together, just as it does at an event.
Open any starter deck in the precon list, clone it into your decks and swap in the cards you own to upgrade it.
Under the official rules, a One Piece deck has one Leader and a main deck of exactly 50 cards, with no more than four copies of any card number. Every Character, Event and Stage must share a colour with the Leader. A separate DON!! deck of 10 cards sits alongside it.
Sign up free and create a One Piece deck, then pick your Leader.

Tune the counters and curve with the stats panel, then publish or keep the list private.
