Deck Command (KHBBS)

Deck Commands are attacks, magic, and item commands that appear on the Command Menu in Kingdom Hearts Birth by Sleep and the Command Matrix in Kingdom Hearts Re:coded. The attacks, magic, and items are abilities that can be equipped from the menu and once used, have a certain cooldown time, depending on the depth of the ability. This system was described to be like the card system in Kingdom Hearts Re:Chain of Memories.

Battle Commands, Action Commands, and special abilities like Shotlock all have levels. When a command levels up, it will be more powerful, and can sometimes have special support abilities attached to it. A command can be leveled up by gaining Command Points from defeating enemies in battle, or by playing the Command Board.

Finish Commands only have one level, but must be mastered before they can be equipped. Instead of gaining experience from obtaining CP, each Finish Command has a specific experience requirement, such as activating a Command Style or slaying Unversed. Furthermore, only Finish Commands linked to the currently equipped Finish Command will accrue experience.

Attack Commands have a Keyblade symbol at the end of their slot, Magic Commands have a Magician hat at the end of their slot, Item Commands have a potion-like symbol at the end of their slot, Friendship Commands have a Hidden Mickey symbol at the end of their slot, Shotlock have a green circle with a three point symbol at the end of their slots, and Defensive Commands have a blue shield with a blue dot in the middle symbol at the end of their slots.

D-Link Commands
Each Dimension Link has its own unique Deck of commands, and while most of these are simply recycled from the normal list of Attack and Magic Commands, the Cinderella, Snow White, and Vanitas D-Link Decks are composed of completely original commands.
