A "card" from the Finest Fantasy 13 deck looks like an enormous compact disc, presumably a game disc. It is predominantly silver and has a white border. The upper half of a black Nobody sigil is present on the right half of the disc, and there is a small, white diamond on the tip on the left spike. There is a black Roman numeral 13 (XIII) on the upper left side.
Finest Fantasy 13 is one of only four of Luxord's weapons whose name is not drawn from one of twenty-two cards that make up a Tarot deck's Major Arcana. The others are The Joker, Fair Game, and High Roller's Secret.
The name "Finest Fantasy 13" is a play on the term "Final Fantasy"; "Ultimate Illusion" as a play on "Final Fantasy" has also been used in Final Fantasy XII as a move used by Gilgamesh. "Finest Fantasy 13" is also a reference to Final Fantasy XIII, a Final Fantasy game released for the PlayStation 3 and Xbox 360 within the same year as Kingdom Hearts 358/2 Days. The name may also be a reference to the compilation, Finest Fantasy for Advance.
According to Tetsuya Nomura in the Kingdom Hearts 358/2 Days Ultimania, this weapon was originally intended to be named "Ultimate Delusion 13" (究極妄想13 Kyūkyoku Mōsō 13?), but the idea was scrapped due to the complaints of the overseas translators.
Finest Fantasy 13's normal ground combo starts with a narrow spray of "cards" forwards and ends with an upward spiral of "cards". The -Combo can be activated after the first attack, and consists of Luxord performing a spinning leap, surrounded in an upward spiral of "cards", followed by riding a larger version of one the "cards" like a surfboard while performing a forward 360-degree spinning attack with larger versions of the "cards" held in each hand.
The aerial combo consists of Luxord throwing his "cards" forwards in a boomerang-like fashion, followed by a spinning leap, surrounded in an upward spiral of "cards", and ends by riding a larger version of one the "cards" like a surfboard while performing a forward 360-degree spinning attack with larger versions of the "cards" held in each hand.
