|This article is about a/an set of transformational implements in Kamen Rider Decade.|
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 Raidā Kādo?). 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.
Kamen Ride Cards
Decade's Kamen Ride Card
The Kamen Ride Cards (カメンライドカード Kamen Raido Kādo?) 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.
- 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. He is also able to use Clock Up without using the Attack Ride: Clock Up card, first shown when battling the Go-Busters.
- 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
When Kamen Rider Decade is in his Complete Form, he uses the K-Touch to summon the Final Forms of the previous Kamen Riders. After he presses the Rider's symbol, a card of that Rider's Final Form appears in a set of nine on Kamen Rider Decade's chest.

Diend's Kamen Ride Cards
Unlike Decade who transforms into another Kamen Rider, Diend uses his KamenRide 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.

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.

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 and Diend's most powerful attacks, used for finishing off enemies.
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. 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.
- When used by Decade Complete Form, the Dimension Kick becomes the Enhanced Dimension Kick.

Decade performs the Final Dimension Kick, a variation of the Dimension Kick, transforming the Shōwa and Heisei Riders into KamenRide cards for Decade to travel through as opposed to Final Attack Ride cards before hitting the target.
- In Kamen Rider: Climax Heroes, Decade has another final attack, Decade Unlimited, Decade Complete Form's Rider Kick, in which instead of Final Attack Ride card holograms, Decade locks the opponent in a dimension that depicts the nine original worlds and then the ten Heisei Rider symbols appear in the same fashion as the Final Attack Ride cards as Decade hits the target with the Rider Kick.

- Den-O: Momotaros executes the Decade Liner similar to Den-O's Extreme Slash, labeled by Momotaros as "My Finisher Attack, Decade Version" (俺の必殺技・ディケイドバージョン Ore no Hissatsu Waza: Dikeido Bājon?).
- 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 Akanetaka transforms into the Hibiki Ongekiko and attaches to the target and allows Decade to perform his version of an Ongeki Da finisher using Hibiki's Ongekibou Rekka.

These cards are seen used by Diend's most powerful attacks, used for finishing off enemies in the series and movies.
- Diend: Diend performs the Dimension Shoot. Nine rings of cards showing the previous nine Heisei Riders appear before the Diendriver. Diend then sucks in any Riders summoned by his KamenRide cards before firing a shot from the Diendriver at the target, coming out as a green and black beam.
- When used by Diend Complete Form, the Dimension Shoot becomes the Enhanced Dimension Shoot which shoots out a gold-colored beam of energy.
- Kiva: With the Kiva Arrow, Diend performs the Diend Fang which fires the arrow, unfolding to hit the target in similarly to Kiva's Darkness Moon Break Rider Kick. Unlike Decade, who holds the arrow vertically, Diend holds it like a crossbow.
- Blade: With the Blade Blade, Diend performs the Diend Edge where the Blade Blade charges with electricity then Diend slashes the enemy, making a huge electric shockwave similar to Blade's Lightning Slash
Decade's Showa Kamen Ride Cards in Final Kamen Attack Form Ride
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.
The Rider Cards, along with the other Rider Powers, were stolen from Decade by Amadum in the world within the Magic Stone, who explained that they were already his due to the Riders' powers being from the same source as evil. However, the power was soon returned thanks to the appearance of Kamen Rider Gaim, with the return of the Rider Cards immediately transforming Decade into Complete Form.
Behind the scenes
Influences to and from Super Sentai
- The "Kamen Rides" preceded the Gokai Changes of Kaizoku Sentai Gokaiger. Like the Kamen Rides, the Gokaigers could transform into any past sentai.
- However, Super Sentai came first with heroes transforming into past heroes in AkaRed, who appeared in GoGo Sentai Boukenger vs. Super Sentai (2006). AkaRed had the ability to transform into past Sentai Reds, he also appeared in Gokaiger.
- In the same vein, the Final Form Rides preceded the Inordinate Power of Hikonin Sentai Akibaranger as like the Final FormRides, the Akibarangers could transform some past Red Rangers into weapons based on their motif. The transformation, however, isn't nowhere near as graphic as in Kamen Rider Decade.
- A nod to the Final FormRides previously occured in the finale of Gokaiger, where Gokai Green, having Gokai Changed into Zubaan from GoGo Sentai Boukenger, changed from its humanoid form to Sacred Sword Mode, expressing discomfort both during and after the transformation, while the original Zubaan in Boukenger was not a human but the Golden Sword Precious itself, being able to assume a humanoid fighting form when the seal on the sword was turned.
- The Rider Cards of Decade and the Ranger Keys of Kaizoku Sentai Gokaiger were noted by Narutaki as one of the similarities between Decade and Gokaiger in the Super Hero Taihen net movie The Grown-ups’ Narumi Detective Agency Ep. 1: Is Gokaiger a Ripoff of Decade?.
- The design of the Rider Cards are similar to PreCards from the 2014 anime series Happiness Charge Pretty Cure! (coincidentally also a 10th anniversary season), both have a barcode on a side and a magenta border. Both are also used to access forms and powers of the main protagonists's abilities.
