ONE PIECE TCG Counter Battle
See the exact counter gap, the fewest declared cards that can cover it, and the odds an unknown hand contains enough live counter value.
attack power → counter gap → odds
Can they get above it?
Attack ties win. To avoid damage or a K.O., the defender needs strictly more power - not equal power.
This uses only counter values you provide. A Counter event needs its cost paid, [Blocker] happens earlier in battle, and card text can alter the standard sequence.
How much counter do I need?
Subtract the defender's current power from the attacker's current power, then add 1. Because normal counter values come in 1000-power steps, round the result up to the next 1000. If the attacker is already below the defender, no counter is needed: the attack loses the battle.
counter required = ceil((attacker power − defender power + 1) / 1000) × 1000
For known cards, the calculator searches every valid mix of the 1000 counters, 2000 counters, and event value you declare. It reports the fewest cards that get the defender above - not merely equal to - the attacker. This matters when deciding whether a hand can actually answer multiple attacks.
What the bluff model means
The optional probability is an exact multivariate hypergeometric calculation over the counter categories you enter. For example, it can distinguish a hand with one 2000 counter from a hand with two 1000 counters. The result answers a narrow question: “If an unknown hand was drawn from this stated composition, what is the chance it has enough value for this one battle?”
It does not know which cards your opponent kept, whether an event is payable, blockers, Life triggers, previous counters spent, or player behaviour. Treat it as deck-composition math, not a read on the person across from you.
Can they counter a 5000 attack with a 5000 leader?
Yes, if they can add at least 1000. The attacker wins a tie, so the defender must reach 6000 to make the attack lose.
Are 2000 counters always better?
They often preserve hand count for a single power gap, but the best use depends on the rest of the attack sequence. The Lethal Calculator lets you test a declared mixed pool across multiple attacks.
Does an Event count as a counter card?
Only if it has [Counter], is in hand, and its activation cost can be paid. This tool asks you to make that availability assumption explicitly.
