Every One Piece TCG set has its chase cards, but OP-18's two Secret Rares stand apart for a reason that has nothing to do with in-game power level.
Both are illustrated by Yoshitaka Amano, the legendary character designer behind the Final Fantasy series, working in a style that looks nothing like the game's usual art direction.
That makes these two cards a genuine crossover-art event rather than a standard alternate-illustration parallel.
Here is exactly what is confirmed about both cards heading into OP-18's November 2026 release.
OP-18 includes two Secret Rare cards with Amano artwork: Loki, a reprint of the OP-17 Secret Rare card now carrying new Amano illustration, and Saint Shamrock, listed as OP18-119, a brand-new Secret Rare Amano original for this set.
Both characters connect to the Knights of God theme running through OP-18, giving the crossover art a direct tie to the set's own story framing rather than feeling like an unrelated bonus insert.
OP-18's overall rarity breakdown lists only 2 Secret Rare slots in the entire 127-card-type set, which is on the lower end for a modern main booster release.
A smaller Secret Rare pool concentrated entirely on the Amano crossover means both cards carry outsized attention relative to their raw pull rate, since there is no split focus with other Secret Rare characters this time.
Loki previously appeared as a black Secret Rare in OP-17, tied to the Elbaf arc storyline, and OP-18 brings the character back specifically to showcase new Amano artwork rather than introducing a new card effect.
Reprints receiving new premium artwork are not unheard of in the One Piece TCG, but pairing a reprint with a completely different illustrator is a notable departure from how the game has typically handled alternate arts.
Saint Shamrock, numbered OP18-119, is a new character card tied to the Knights of God faction and marks the character's first appearance as a Secret Rare in the game.
As a genuinely new Amano illustration rather than a reprint, this card is likely to draw comparably strong attention from both competitive players and pure art collectors.
Reporting around the reveal points to foil-stamped parallel versions confirmed for both Amano cards, which typically means a base Secret Rare version and at least one premium parallel finish.
Exact parallel names and print run details have not been published in full yet, so treat specific parallel-rarity claims as provisional until Bandai's official card list goes live closer to release.
With only two Secret Rares total in the set, pulling either Amano card from a single booster box is genuinely unlikely, and most collectors chasing these two cards specifically will end up buying singles rather than relying on box odds alone.
That dynamic is exactly what tends to happen with crossover-artist chase cards historically -- box-opening demand rises, but the realistic path to owning the card for most buyers is the secondary market.
Whether you pull an Amano Secret Rare from a box or buy one as a single, the sealed box it came from is still worth protecting if you plan to keep any part of your OP-18 purchase intact.
A rigid display case is a practical way to keep an unopened box safe on a shelf while you decide whether to chase these cards through box openings or the singles market.
Bandai and the official One Piece Card Game English social accounts have been the primary source confirming details about Loki and Saint Shamrock so far, rather than general aggregator sites summarizing secondhand.
Following those official channels directly, alongside dedicated trade press covering the reveal, is the most reliable way to catch any updates to parallel treatments or print details before the November 2026 release.
