One Piece Card Game OP-18: God's Knights Super Parallel, Saint Gunko, and the Latest Card Reveals

Spoiler season for The Dominance of God is well underway, and Bandai has been drip-feeding OP-18 card reveals on the official One Piece Card Game X account under the series tag "OP-18カード紹介". With the Japanese release confirmed for 21 November 2026 and the English version following on 20 November, there is plenty to digest right now.

A Brand-New Rarity for the 4th Anniversary

The headline reveal from a collector's perspective is a rarity that has never appeared in the card game before. A new treatment called the God's Knights Super Parallel — 神の騎士団スーパーパラレル — has been reported for Saint Gunko (Saint Gunko / 軍子宮), one of OP-18's marquee characters. Bandai announced OP-18 at ONE PIECE DAY'26 as the second 4th-anniversary booster after OP-17, and this new Super Parallel rarity appears to be part of that anniversary celebration — a direct response to the community's appetite for premium treatments on the most sought-after cards.

For UK collectors who chased the Amano Secret Rares in OP-17, this new rarity tier is worth watching closely. If previous anniversary sets are any guide, God's Knights Super Parallels are likely to command meaningful premiums at launch.

Holy Knight Debuts: Gunko and Shamrock Enter the Game

OP-18's official product page confirms two first-time appearances in the card game: Saint Gunko and Saint Shamrock. Both are Holy Knights of God, the powerful antagonist faction that has loomed large in the manga's Egghead and Mary Geoise storylines. Their debut adds genuine meta weight — Holy Knights have been narratively significant for years, and their absence from the card game has been a talking point in the community. Bandai is clearly using OP-18 to bring that faction to life mechanically, following on from the Water Seven and CP9 themes that the set also covers.

Water Seven Returns

Alongside the Holy Knights, OP-18 revisits Water Seven — one of the most beloved arcs in the entire series. The September 2026 reveal wave included a card featuring 海ネコ (Sea Cat), a minor but fan-favourite Water Seven character, suggesting Bandai intends a broad sweep of the arc rather than just its headline fighters. For players, Water Seven support could breathe new life into Blue and Black strategies built around CP9 and Galley-La characters introduced in earlier sets.

As of 1 October 2026, nine OP-18 cards carry confirmed numbers per Japanese card-list trackers Tier One and meli-melo, with more being added to Bandai's X feed regularly.

What to Expect Before the UK Release

The English release is lined up for 20 November 2026, slotting neatly into the pre-Christmas window. With OP-17 having landed in late August and the Heroines Special Set covering September, OP-18 gives the UK market a clear focus point for autumn. The set will follow the standard English format of 24 booster packs per display box with 12 cards per pack, and carries a total of 127+1 card types — a count consistent with recent mainline boosters.

Pre-orders are already live at several UK retailers, and given how quickly OP-17 allocation moved at launch, it is worth securing a spot sooner rather than later if you are planning to crack boxes.

Keep an eye on the official One Piece Card Game X account for further daily reveals as we head through October — the pace of drops typically accelerates in the six weeks before a Japanese street date.
