How to Start Playing the One Piece Card Game
A plain-English start for complete beginners: what the game is, what goes in a deck, how a turn works and what to do with the cards you already own. Everything here comes from the publisher's own rule pages.
What the game is and how you win
The One Piece Card Game is a two-player trading card game. You build a crew around one Leader card, then attack your opponent's Leader again and again to run down their Life.
You win in one of two ways. Either you win a battle against your opponent's Leader when they have no Life cards left, or your opponent's deck runs out of cards.
What a deck is and what goes in it
A deck is the set of cards you play with. The official rules list three pieces:
- 1 Leader card. It sits face up from the start, shows your colour(s) and has a Life number. That number decides how many Life cards you start with.
- A 50-card main deck made of Character, Event and Stage cards. Every card must match a colour on your Leader, and you may only have 4 copies of any one card number.
- A 10-card DON!! deck. DON!! cards are your energy. You rest them to pay card costs, or attach them to a Leader or Character to give it +1000 power on your turn.
Play sheets are not required, but the rule manual recommends one per player.
What a turn looks like
To set up, shuffle your deck, place your Leader, decide who goes first, draw 5 cards (you may redraw the hand once) and put cards from the top of your deck face down as Life. Then the first player starts.
Every turn follows the same five phases, in order:
- Refresh: make all your rested cards active again and return attached DON!! cards.
- Draw: take a card from your deck.
- DON!!: add DON!! cards from your DON!! deck to your cost area.
- Main: play cards, give DON!! and attack, in any order, as often as you can.
- End: end-of-turn effects happen and your opponent's turn begins.
How an attack works
An attack is where the game is decided. Rest one of your active Leader or Character cards and name a target: the opponent's Leader, or one of their rested Characters. Neither player can attack on their own first turn.
The defender then gets two chances to react. They can use a Character's Blocker effect, and they can play Counter effects to raise their power. After that, the card with the higher power wins the battle.
If your attack beats a Leader, it takes 1 damage and the top card of their Life goes to their hand. If it beats a Character, that Character is K.O.'d. An attack on a Leader with no Life left wins you the game.
What to buy first
You only need product types to start, and the official site groups them simply: decks, boosters and other merchandise. The site describes decks as ready to play, with everything you need in one set.
- Starter decks are the best first purchase. A starter deck is a complete deck you can play straight away, and two of them let you play a first game with a friend.
- Booster packs add new cards to your deck or collection. Buy them once you know which Leader and colour you enjoy.
Check the official products page for what is current rather than relying on an old list.
Reading a card: code, rarity and versions
Every card shows a card number made of a set code, a hyphen and three digits, for example the pattern OP01-001. The set code tells you which product the card belongs to. Deck limits are counted by this card number.
The official card list shows six rarity labels: L (Leader), C, UC, R, SR and SEC. Rarity is printed on the card next to the number, so you can always read it directly.
Japanese and English cards use the same game rules but are printed separately, so read Japanese vs English One Piece cards before buying. Extra-artwork versions are covered in card variants explained.
Where to learn for free
The publisher offers several free ways to learn before you spend anything:
- The official Rule Manual, a short PDF that covers everything in this guide.
- A tutorial video and a Quick Beginner's Guide on the official learning page.
- The Play Guide, a quick reference you can keep open during a game.
- The official Teaching App, which lets you practise against the computer before playing a friend.
- Official shops, which run tournaments and teaching events where someone will show you the game.
If a card's text ever disagrees with the manual, the rule manual says the card text wins.
What to do with cards you already own
Maybe you already have a stack of cards from a pack or a relative. Start by sorting them: keep Leaders in one pile, then group the rest by colour. A Leader plus cards of its colours is already the start of a deck.
Put anything you like in a soft sleeve, and anything that looks valuable in a sleeve and a rigid holder. Keep cards dry and out of sunlight.
To find out exactly which card you are holding, open the free U.C.M app and scan it. It identifies the card and shows its details, so you do not have to guess from the number. The One Piece card scanner page explains how it works.
The fast way: scan it
Open U.C.M, point your phone at a card or a sealed product and it looks for the exact print and shows the official picture and today's market price. It is free to download, and the free plan includes 3 scans per week.
Questions
How many cards do I need to play the One Piece Card Game?
You need one Leader card, a main deck of exactly 50 cards and a separate DON!! deck of 10 cards. You can include up to 4 copies of the same card number, and every card must match a colour on your Leader.
What are DON!! cards used for?
DON!! cards are your energy. You rest them to pay the cost of Characters, Events and Stages. You can also attach them to your Leader or a Character, and each attached DON!! card adds 1000 power during your turn.
Can I attack on my first turn?
No. According to the official rule manual, neither player can attack on their first turn. You can still play cards and give DON!! on that turn, so you are ready to attack on your second.
Do I need a starter deck, or can I just buy booster packs?
A starter deck is easier because it is a complete, ready-to-play deck. Booster packs add cards to a deck you already have, so they make more sense once you have played a few games and know your favourite Leader.
Can I use the U.C.M app to learn the rules?
The app is built for identifying cards, not teaching rules. Use the official Rule Manual and Play Guide to learn how to play, then use the free U.C.M app to scan and organise the cards you own.
