Two users run side by side while leaning their upper body forward, quickly getting into position and simultaneously executing a cartwheel. They then turn their backs around, performing a series of rapid backflips and coming to a sudden halt, crouching themselves to the ground while placing both of their hands on the field, abruptly springing and spinning towards the airbone ball. Once they close in on the ball, the surrounding area turns into a spacelike dimension, overheading it with both of their feet at the same time, covering it with bright orange energy as it briskly falls down towards the goal, changing itself into a planetary projectile spiraling in a veil of flames, akin to a meteorite.
