Unison Rush

Unison Rush is a Advanced-class Friendship Command usable by Terra, Ventus, and Aqua in the North American, PAL, and Final Mix versions of Kingdom Hearts Birth by Sleep.

Mechanics
In Kingdom Hearts Birth by Sleep, Unison Rush involves all three players rushing around the field and attacking enemies with their Keyblades, prompting them to press the button on-screen for maximum damage, similar to a type of Shotlock. It is most effective during Mirage Arena battles. It takes up three slots in the Command Deck, has a maximum level of 1, and a normal reload time of 50 seconds.
