Rider Cards

Like the Heisei Riders in Kamen Rider Ryuki and Kamen Rider Blade, Decade has card-based weaponry and powers: the Rider Cards. 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.

Kamen Ride Cards
The Kamen Ride Cards supposedly possess all the powers of the 9 previous Heisei Kamen Riders. 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 KamenRide Cards go black while fighting Dark Kiva, later they are regained.
 * 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 Yuusuke'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 the card to assume the form of Ryuki. Decade can also travel through mirrors like the original Ryuki.
 * Blade: Regained when Tsukasa shows Kazuma that even followers are important as leaders, Decade uses the card to assume the form of Blade.
 * Faiz: Transforms Decade into Faiz, initially sealed after being used once. Regained when Tsukasa teaches Takumi that protecting those dear matters regardless of who he is.
 * Agito: Regained when Tsukasa teaches Shouichi (and Yuusuke) 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.
 * 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 KamenRide 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.
 * In Kamen Rider × Kamen Rider Double & 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.

Form Ride Cards
Form Ride Cards allow Decade to assume any of the forms the Heisei Riders have. Accessing these forms grants Decade the use of any weapon exclusive to that form. Generally, Decade changes forms within one Rider's forms. However, Decade does not have to be a particular Rider to transform into one of that Rider's alternate forms.
 * Kuuga Dragon: Decade assumes Kuuga's Dragon Form.

Final Attack Ride Cards
The Final Attack Ride Cards (ファイナルアタックライドカード, Fainaru Atakku Raido Kādo) are Decade's most powerful attacks, used for finishing off enemies. 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. If the Final Attack Ride is used when Decade is in Complete Form, he can perform that Rider's signature move (in their ultimate form) alongside the summoned Rider using the Ride Booker to improvise if the attack uses a weapon.
 * Decade: Decade performs the Dimension Kick, Decade's Rider Kick. With the Ride Booker in Sword Mode, Decade can execute a highly charged slash called the Dimension Slash. While in Gun Mode, Decade can execute a highly charged shot called the Dimension Blast. All attacks involve the Decadriver generating large golden Final AttackRide cards, which Decade leaps/runs/shoots through, the final card having an image of Decade's attack before he bursts through it. These hologram cards can also stun the enemy before the attack connects and can line up to track the enemy. In the Ganbaride game, Decade has another final attack, Decade Vanish where he captures the enemy in energy barcode, scanning the target before finishing him off.

Decade performs the Final Dimension Kick (ファイナルディメンションキック, Fainaru Dimenshon Kikku), a variation of the Dimension Kick, transforming the Shōwa and Heisei Riders into Kamen Ride cards for Decade to travel through as opposed to Final Attack Ride cards before hitting the target.
 * Kuuga: While in Gouram form, Kuuga rushes toward Decade with the target stuck in his pincers while Decade performs the Mighty Kick-like Decade Assault flying kick towards the target.

 * Kabuto: The Zecter Kabuto charges at the opponent in a devastating mid-air body slam, Decade Meteor. With the target left vulnerable in mid-air, Kabuto and Decade execute their respective kick attacks while in Clock Up. The same card can be used by Decade in Kabuto's Rider Form to execute Kabuto's Rider Kick.
 * Hibiki: With Hibiki Ongekiko, Decade performs the Decade Wave, where Hibiki Ongekiko attaches to the target and allows Decade to perform his version of an Ongekida finisher using Hibiki's Ongekibou Rekka.
