Nami starts the list at number ten because she is one of the most popular characters in One Piece and this alternate art is one of the better-looking cards in the set. It may not be the most valuable card from OP-15, but the combination of character demand and strong artwork is enough to earn it a place in the top 10.

Lightning Dragon ranks ninth because manga event cards are visually stunning and still difficult to pull, even if they are not as rare as full manga rare character cards. These cards appear at roughly one in 144 packs, making them exciting hits for collectors. Of the manga event cards in OP-15, Lightning Dragon is likely to be the one many collectors prefer.

Zoro ranks eighth because treasure rares are language-exclusive cards, and this English-exclusive Zoro is one of the best-looking treasure rares released so far. Zoro is already one of the most popular One Piece characters, so combining that popularity with the low pull rate of treasure rares makes this a great hit from any OP-15 pack.

Sabo ranks seventh because this full-art special rare has strong visual appeal and enough character popularity to make it a desirable pull. This card originally appeared in the Japanese EB-04 release, and its inclusion in English OP-15 gives collectors another strong special rare to chase. Sabo may not be the most popular character in the set, but he still has a loyal fanbase.

Edward Newgate, better known as Whitebeard, takes sixth place over some of the more expensive special rares because of the strength of the artwork and the fact that he does not receive alternate art cards as often as some other major characters. The cracked effect across the card is a great way to represent his Devil Fruit powers and makes the design feel especially memorable.

Luffy sits fifth because he is the face of One Piece and one of the safest characters to rank highly in almost any set. Even when another card is rarer or more valuable, a strong Luffy card will usually be one of the most searched, most recognisable and most satisfying pulls for collectors. A special rare Luffy card of this quality was always likely to be one of the standout cards from OP-15.

Boa Hancock takes fourth place because her chase cards almost always attract strong collector interest. Alternate art and special rare versions of Boa tend to hold attention well, and this card is no different. While some previous Boa cards from sets such as OP-12 and EB-03 may have more striking artwork, this OP-15 special rare still has enough character demand to sit comfortably near the top of the list.

Zeus is not the most popular character in One Piece on his own, but the real strength of this card comes from Nami. Nami is extremely popular with collectors, and the inclusion of other Straw Hats in the artwork helps push this special rare even higher. It is one of the best-looking cards in OP-15 and a very strong pull for collectors who enjoy character-focused artwork.

Koby ranks second because he gives the English OP-15 release another major manga rare chase. In the Japanese version of the card game, Koby was the manga rare from EB-04. Because part of that release was folded into the English OP-15 set, Koby appears here as one of the biggest cards to pull. He may not be as popular as Enel, but the manga rare status makes him one of the clear top cards from the set.

Enel takes the top spot because he is the obvious headline chase card from OP-15. His value comes from a strong mix of manga rare status, character popularity and direct relevance to the Skypiea theme. Manga rares are extremely difficult to pull, so it is hard to argue for any other card above him.
