OP-18 The Dominance of God: release date, booster box contents and pre-order in Belgium

OP-18, The Dominance of God, is the next One Piece Card Game booster set in English. Here is what we know about the release, what is inside a booster box, and how to get one shipped from Belgium on release day.

OP-18 release date in Europe

The English version of OP-18 is released on 20 November 2026. Pre-orders are open now, and every pre-order is reserved from our first shipment, so your box ships the day the set lands in Belgium. You can see all upcoming dates on our One Piece release calendar.

What is inside an OP-18 booster box

• 24 booster packs per display
• 12 cards per pack
• 126+1 card types to collect
• Alternate art cards and parallel foil designs

The box is also called a display. It is the standard product players open to build decks, and the one collectors open to chase the best cards of the set.

Sealed or unsealed: which one should you get?

We offer OP-18 in two versions with exactly the same packs inside:

• Sealed: factory shrink wrap intact. The best choice for collectors and anyone who wants to keep or resell the box.
• Unsealed: we remove the shrink wrap, so you get the same 24 packs at a more accessible price. Ideal if you are going to open it anyway.

English or Japanese OP-18?

Japanese sets come out months earlier and are often cheaper per pack, but you can only play English cards at official English events. If you play locally in Belgium or the Netherlands, English is the safe choice. Our guide Japanese vs English One Piece cards explains it in detail.
