Launch is move in Grifball where one uses their hammer on the ally runner as he jumps, and the gravity effect of the hammer sends him flying. A perfect launch can send the runner farther and higher than a flower would. It’s also quicker to have your teammate launch you than it is to drop the ball on the ground and flower. The only issue with a launch is that the runner usually ends up with low or no shields from his teammate’s hammer. In that regard flowering can be better.
