One Piece OP-18 The Dominance of God: release date, products and pre-orders (UK)

One Piece Card Game OP-18, officially BOOSTER PACK -THE DOMINANCE OF GOD- [OP-18], releases on 20 November 2026. Bandai lists 127+1 card types. Saint Gunko and Saint Shamrock make their debut, and two cards are illustrated by Yoshitaka Amano. English booster boxes hold 24 packs of 12 cards. Iconic Trading Cards has both the OP-18 booster box and single packs on pre-order now.

When is OP-18 released?

Bandai's official English product page gives 20 November 2026. Earlier in the year Bandai's English account only said "November 2026", and some retailers listed other November dates. The official page is the one to trust, and it's the date we work to. Iconic Trading Cards dispatches OP-18 pre-orders on or around 20 November. Release dates are set by Bandai and can occasionally move. If the date changes, we update the product pages and our OP-18 pre-order page first.

What is The Dominance of God about?

The title points at the Holy Knights of God, the enforcers of the Celestial Dragons. Two of them, Saint Gunko and Saint Shamrock, make their One Piece Card Game debut in this set. That makes OP-18 a set built on some of the most talked-about characters in the recent story, which usually means strong demand for the Leader cards and their parallels.

The other headline is the art. Bandai's English account announced that OP-18 "features 2 colossal characters illustrated by the legendary artist Yoshitaka Amano". Amano is famous for his Final Fantasy artwork. Expect those two cards to be the ones everyone opens a box hoping for.

What's in an OP-18 booster box?

Product	Contents	Best for
Booster box	24 packs × 12 cards = 288 cards	Opening the set properly, building the new Leaders, chasing the Amano cards
Booster pack	12 cards	Trying the set, adding a few packs to an order, gifts

Bandai adds its usual warning: because the product is randomised, you can get duplicates, and one box may not complete a set. If you need specific cards for a deck, singles are cheaper than chasing them. If you want the full experience and the best odds at the top rarities, the box is the only sensible buy.

How much does OP-18 cost in the UK?

Bandai publishes a suggested US price of $4.99 a pack but no UK RRP. UK prices are set by each retailer. Ours are shown on the product pages, and UK delivery on sealed product is £3.95.

Is OP-18 tournament legal straight away?

Bandai says the cards are legal at your local game store from its pre-release date, and in official tournaments 7 days after the release date in your region. If you play at a local store, you can bring OP-18 cards to events as soon as the store has run its pre-release.

Where does OP-18 fit?

OP-18 follows OP-17: The World's Strongest Warriors, the fourth-anniversary set released in August 2026. That set is still available in our OP-17 collection. If you are new to the game or coming back to it, our One Piece Card Game UK guide covers the sets in order, English vs Japanese, and where to start. Loose packs from earlier sets are in One Piece single packs, and the full range is in our One Piece collection.
