OP-16: The Time of Battle

OP-16: The Time of Battle is the sixteenth official booster set of the One Piece Card Game and was released on 12 June 2026. The main theme is the Paramount War: the war at Marineford that turned the balance of power in the series upside down.

The set contains six Leader cards, one per colour. That is the layout Bandai has kept to in the more recent sets: every colour gets a new Leader, so there is something new to build in each colour pairing.

Paramount War was already the theme of OP-02, and that is what makes this set interesting: the same event, but with years of new game mechanics behind it. The parties around Marineford — the Marines, the Whitebeard Pirates and the Shichibukai — return here in versions that did not exist in 2023.

Above you will find what we have from OP-16 in stock, in both English and Japanese.
