Rider Cards

Like the Heisei Riders in Kamen Rider Ryuki and Kamen Rider Blade, Decade has card-based weaponry and powers: the Rider Cards (ライダーカード). However, due to a seal placed on them all, Tsukasa travels across the world to undo the seals and regain the abilities the cards endow. These cards match up with Bandai and Carddas's arcade card game, Kamen Rider Battle: Ganbaride.

Like Decade, Diend has possessed his own set of Rider Cards.

Decade's Kamen Ride Card
The Kamen Ride Cards (カメンライドカード) supposedly possess all the powers of the 9 previous Heisei Kamen Riders, along with Shōwa Kamen Riders as seen in Super Hero Taisen. Because they were sealed, Tsukasa must touch the heart of a world's Kamen Rider in resolving an issue threatening that world. Though he regained his abilities from his journey, the Kamen Ride Cards go black while fighting Dark Kiva, but are regained later on. A Gackt Kamen Ride Card featured in the "Journey through the Decade" and the "Stay the Ride Alive" music videos.
 * Decade: Initial card; transforms Tsukasa into Kamen Rider Decade. Tsukasa must use this card first before assuming any other transformations.
 * Kuuga: Regained when Tsukasa gains Yusuke's trust. Decade uses the card to assume Kuuga's Mighty Form.
 * Kiva: Regained when Tsukasa acknowledges Wataru as the Fangires' King. Decade uses the card to assume Kiva's Kiva Form.
 * Ryuki: Regained when Tsukasa and Shinji work together to defeat Kamen Rider Abyss, Kamata. Decade uses this card to assume Ryuki's Ryuki Form. Decade can also travel through mirrors like the original Ryuki and can summon the Drag Saber without the need of an Attack Ride Card.
 * Blade: Regained when Tsukasa shows Kazuma that even followers are important as leaders. Decade uses the card to assume the form of Blade's Ace Form.
 * Faiz: Transforms Decade into Faiz, initially sealed after being used once. Regained when Tsukasa teaches Takumi that protecting those dear to him matters regardless of who he is.  Sometimes, Decade can summon Faiz Edge without using Attack Ride: Auto Vajin.
 * Agito: Regained when Tsukasa teaches Shouichi (and Yusuke) that you can't run away from your problems. Decade uses this card to assume the form of Agito's Ground Form.
 * Den-O: Regained when Tsukasa refers to Momotaros by his real name after calling him kind-hearted and restoring his sense of self. Decade uses this card to assume the form of Den-O's Sword Form.
 * Kabuto: Transforms Decade into Kabuto's Rider Form, used once before its power is sealed. Regained when Tsukasa taught Mayu the true meaning about her Grandmother's saying of looks being deceiving while praising Souji's family bonds. During Super Hero Taisen event, Tsukasa is shown to be able to summon the Kabuto Kunai Gun while using the Kabuto card.

 * Hibiki: Transforms Decade into Hibiki, used once before its power is sealed. Its silhouette turned black after Hibiki's metamorphosis into Gyūki.  Regained after Asumu becomes Hibiki and Tsukasa learns the true meaning of the Ongekidō.
 * Decade Complete: A Final Kamen Ride Card, manifesting after Tsukasa regains his ability to become Decade. By inserting the card into the K-Touch, it transforms Decade into Complete Form.
 * Black: A card containing the power of Kamen Rider Black. Diend borrows it to summon Kotaro from the World of Black while in the World of Black RX, as he claims that Decade cannot use the card. But in theory, this card allows Decade to transform into Kamen Rider Black.
 * In Kamen Rider × Kamen Rider W & Decade: Movie War 2010, Decade acquires Kamen Ride Cards for all of the Kamen Riders he defeats, including Skyrider, Super-1, and J. Amongst these cards is also the Kamen Rider Skull card but unlike the others, it is sealed (he later gave it to Kamen Rider Double). Decade kept these cards after all the Riders were restored.
 * 1: Transforms Decade into Kamen Rider 1. Unlike other Kamen Rides, this form is a full transformation as the Decadriver was concealed in the form of Kamen Rider 1's belt, the Typhoon. First used in Super Hero Taisen.
 * Diend: Tsukasa had to use this one while in Complete Form in order to perform Dimensional Shoot along with Diend. In the novel, which is a reimagination of the TV Series, Kaito died and Tsukasa had also use the card which turn himself into a cyan colored version of Decade in order to battle Narutaki's monster form.

Complete Decade's Final Kamen Ride Cards

Diend's Kamen Ride Cards
Unlike Decade who transforms into another Kamen Rider, Diend uses his Kamen Ride cards to summon other Kamen Riders. Diend is not limited to just the nine previous primary Kamen Riders, but has access to any Kamen Rider who has appeared in the Heisei period. The cards of the Extra Riders, including his own, differ from Decade's main nine cards using a white background as opposed to a black one. Eventually, Diend is able to summon Riders from the Showa period as well. Diend has summoned, at most, three different Kamen Riders at once.

When using Kuuga's Form Ride Cards, Decade gains Kuuga's ability to turn normal items or weapons into their respective weaponry.

Decade's Final Attack Ride Cards
The Final Attack Ride Cards, if used in conjunction with the Final Form Rides, can allow Decade to perform an attack with that Rider's Final Form (which usually resemble that Rider's own signature attack in some way). If the Final Attack Ride is used in conjunction with Kamen Ride Cards, they allow Decade to perform the signature attack of the Rider he is transformed into.
