What mechanism are you or other teams using to lift the balls up to your firing mechanism to be shot at the flags.
The most common ball lift mechanisms tend to be rollers or belts powered together with the intake system.
we are using a rubber band intake with a paddle belt thingy that travels up and falls (guided by plexi-glass) into our puncher. Flywheels are normally the easiest to lift ball to because the ball can go right into it from below but most other launchers need the ball to fall from above.

There are many examples of feed systems on other existing robots.
