Deck Command

Deck Commands are attacks, magic, and item commands that appear on the Command Menu in Kingdom Hearts Birth by Sleep. 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.

Deck 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.

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.
