Your first One Piece Card Game match probably felt strange in one specific way: there is no land, no mana crystal, no ink. Instead you have a separate little stack of ten DON!! cards sitting next to your deck, and every turn a couple of them slide into play. Then you discover you can also stick them under your Leader to make attacks bigger, and suddenly every turn has a puzzle in it.
That puzzle is the heart of the game. This guide explains how the DON!! deck works, the difference between spending DON!! and giving it, and how to plan turns so your resources are never wasted.
🏴☠️ What is the DON!! deck?
Every player has two decks. The main deck has 50 cards, with up to four copies of any card number. The DON!! deck is separate and holds exactly 10 DON!! cards. You never draw DON!! cards into your hand. They move from the DON!! deck into your cost area as the game goes on.
Your Leader card sits apart from both decks. It sets your deck's colors, can attack, and has a Life value. At the start of the game, you take that many cards from the top of your deck and place them face down as your Life cards.
You win by landing a successful attack on the opponent's Leader when they have no Life cards left. A player also loses if their deck runs out.
⏫ How does DON!! grow each turn?
During your DON!! phase, you move two DON!! cards from the DON!! deck into your cost area. The one exception is the very first turn of the game: the player going first gets only one DON!!.
So your available DON!! grows quickly until the DON!! deck is empty. At the start of each turn in the refresh phase, all your DON!! cards return to active (upright), and any DON!! you gave to characters or your Leader returns to your cost area.
| Turn (your own) | DON!! you can use, going first | DON!! you can use, going second |
|---|---|---|
| 1 | 1 | 2 |
| 2 | 3 | 4 |
| 3 | 5 | 6 |
| 4 | 7 | 8 |
| 5 | 9 | 10 |
| 6 and later | 10 | 10 |
These totals assume no card effects add or remove DON!!. Many decks do change these numbers, which we cover below.
There are also a few first-turn rules: the player going first does not draw on that turn, and neither player can attack during their own first turn.
💰 What is the difference between paying and giving DON!!?
This is the core decision of every turn. Active DON!! in your cost area can be used in two main ways.
Paying costs. To play a character, event or stage, you rest (turn sideways) DON!! equal to its cost. Rested DON!! cannot be used again that turn.
Giving DON!!. You can attach active DON!! cards to your Leader or a character. Each DON!! given adds +1000 power during your turn. This makes attacks harder to stop and helps your attackers beat the opponent's defenders.
Every DON!! you give is one you cannot use to pay for cards, and the other way around. That tension is the main puzzle of the game: do you develop your board, or do you push damage now?
Tip: At the start of your main phase, decide your plan before touching any DON!!: "This turn I play X and give the rest to my Leader," or "This turn I give everything to attackers and play nothing." Mixing the two without a plan often leaves you with an underpowered attack and an empty board.
A sample mid-game turn
Say it is your fourth turn going second, so you have eight DON!! available. Your hand holds a five-cost character you want on the board and a cheap event. Your Leader is ready to attack.
One option: rest five DON!! to play the character, then give the remaining three to your Leader for an extra 3000 power on its attack. Your board grows and your Leader's attack forces counters. Another option: skip the character and give all eight DON!! across your Leader and an existing character, aiming to push two Life cards in one turn. That is more aggressive but leaves you with nothing new on the board.
Neither is always right. If the opponent has a big hand and plenty of counters, developing the board is usually safer. If they are low on cards and Life, the all-in attack may end the game sooner. The point is to choose on purpose, not to drift into a half-and-half turn.
⚔️ How does attacking work with DON!!?
To attack, you rest your Leader or an active character and target either the opponent's Leader or one of their rested characters. Then the opponent gets chances to respond.
- Blocker. A character with Blocker can rest to take the attack instead.
- Counter. The defending player can discard character cards with a counter value from hand, or play counter events, to add power to the defender for that battle.
- Result. If the attacker's power is equal to or higher than the defender's, the attack succeeds.
When an attack on the Leader succeeds, the defending player takes one Life card into their hand. Some Life cards have a Trigger effect that can be activated when they are revealed this way.
That is where DON!! comes in. Giving DON!! raises your attacker's power so the defender needs more counters to survive. Forcing the opponent to discard counters from hand is a resource win, even when the attack fails.
Planning attacks with DON!!
- Which attack do I want to land most this turn?
- How much power do I need to force counters or get through?
- Should I give DON!! to the Leader, who attacks every turn, or to a character?
- Do I have enough left to play the card I need for defense next turn?
- Are there Blockers on their side I need to deal with first?
🔁 How do DON!! minus effects and returning DON!! work?
Some cards have abilities marked with a DON!! minus symbol, such as "DON!! −1" or "DON!! −2". To use these, you return that many DON!! cards from your field to your DON!! deck. This is a cost: those DON!! cards are gone for now and have to come back through the DON!! phase.
Other cards have the opposite effect, adding extra DON!! from your DON!! deck to your field or making some DON!! active again. These change the pace of your game.
Leaders and characters can also have abilities that check how many DON!! are given to them. A Leader might gain an effect if it has a certain number of DON!! attached, for example. Reading these conditions carefully helps you choose where to give your DON!!. When a Leader rewards having DON!! attached, giving to it first and paying for cards second can unlock an extra effect for free, so check your Leader's text before every main phase until it becomes routine.
Because DON!! returns to the cost area during your refresh phase, giving DON!! does not cost you DON!! permanently. It only matters for that turn. DON!! minus effects, by contrast, send cards back to the DON!! deck, which is a real cost.
🧠 What are smart habits for using DON!! well?
Experienced players handle DON!! in ways that become second nature over time. Some habits worth building early:
- Use all your DON!! every turn. Unused DON!! is wasted, because it refreshes next turn anyway.
- Curve your deck to match the DON!! growth. Have cards to play at each step, so turns with five or six DON!! are not empty.
- Give leftovers to the Leader. If you have spare DON!! after playing cards, attaching them to an attacker is almost always better than leaving them unused.
- Watch your opponent's hand size. A big hand often means many counters, so you may need extra power to break through.
- Save room for defense. Sometimes the right move is to play a Blocker or keep cards for counters instead of attacking with everything.
It also pays to read your opponent's DON!! the same way you read your own. Count how many they have available next turn and think about what that lets them play. If they will hit a number that unlocks a strong character or a big Leader effect, you may want to hold counters or keep a Blocker ready. Since DON!! growth is so predictable, you can often see the opponent's best turn coming one turn in advance.
The official One Piece Card Game site has a rule manual and play guide that cover these details. If you play in person, a local store event is a good place to ask questions and see how other players sequence their DON!!.
🏁 How does DON!! tie the whole game together?
The DON!! system replaces the usual mana in a way that makes every turn a choice. Each DON!! can either pay for cards or add power to attacks, and you rarely have enough for both. Learning to plan that split at the start of each turn is the main skill the game asks of you.
Use every DON!!, plan your attack power against your opponent's likely counters, and treat DON!! minus costs as real investments. With those habits, your turns will feel less like guesses and more like plans.
