These cards are held in the Riders' Advent Decks and can be scanned via their Visors. There are a wide array of different Advent Cards that are attributed to each Rider. Some are unique, but most Riders share a select few amongst each other. With the exception of the Contract, Seal, and Survive Cards, all Advent Cards are named with "(Blank) Vent". In Ryuki, the cards of the Alternatives are of a very different design than the normal Riders' cards, having been made after the fact as an attempted imitation; in Dragon Knight, the Advent Master's cards differing in design is not addressed, though they may represent a prototype stage.
