The card-drawing strategy focuses on Main Planet and Precision. For Wind Song, only pick up excellent attack speed components. The absolute core items are Sheet Music Galaxy, Telescope, and Black Star. Pilots can also use Machine Guns and Gatling Guns; the advantage of the Flower Stick lies in its blocking capability and freedom of movement.
