One Piece DON!! Guide: Pay Costs, Build Attacks, and Keep Defense
DON!! is the decision that connects almost everything in One Piece. Spending enough to build a strong board can leave an attack too small. Giving too much to one attacker can leave a defensive Event stranded in your hand.
The ordinary resource cycle
Your separate DON!! deck contains ten cards. During the DON!! phase you normally add two to your cost area, with the first player's opening turn limited to one. During refresh, attached DON!! returns to your cost area and rested cards become active. Effects can change how quickly you develop or where DON!! moves.
Paying and giving do different jobs
Ordinarily, pay a card's cost by resting active DON!! in the cost area. Giving active DON!! from that area to your Leader or a Character supplies +1000 power per attached DON!! during your turn. A DON!! xN requirement checks the attached amount; it is not the same instruction as resting N DON!! to pay a cost.
Normal attachment uses active DON!!. Some card effects specifically move rested DON!! onto a card. Follow that permission when it exists; do not treat it as the default action available to every deck.
Plan a turn backward
Imagine six available DON!! and a four-cost Character you want to play. If you also need a one-cost defensive Event next turn, earmark one active DON!! for that Event. You now have one DON!! left for an attack increase or another play. Decide whether that increase creates a useful pressure point before committing it.
This is a planning example, not a rule that spending four and saving one is always best. When an opponent has no meaningful attack, more development can be sensible. When you are facing several lethal attacks, that one reserved resource may be the most important part of your turn.
Read DON!! minus carefully
A DON!! minus cost returns the required number from your field to the DON!! deck. It reduces future resources on the field until you rebuild. Count what remains before deciding which cards to play afterward. A strong effect can still leave an awkward next turn.
A practice exercise
- Place six DON!! in the cost area and choose a plausible hand.
- Describe a turn focused on developing Characters.
- Reset and describe a turn focused on attacking.
- Reset again and leave the resources your defense requires.
- Compare what each plan gives the opponent permission to do.
The useful habit is assigning every DON!! a job before moving any of it. You can revise the plan as effects resolve, but you should know what you gave up when you change it.
