Servos are a very bad choice because you will be shifting at top speeds.
You just need to have a pneumatic tank, valve, solenoid, all the basic components. You may be able to run off an external compressor, and precharge the cylinders!

Servo's aren't a very bad choice. They're a great solution if you're only looking to shift a few times a match while you're not moving.

Servos have very little output torque, as compared to a piston.

This is false, as pneumatic cylinders have no torque. You can also gear up your servo or use an alternate motor.

Also, designing the system with pneumatic pistons would be very easy!

Yes, but a servo is easier. The super shifter comes by default with a servo. You'd need to spend more money and assemble an extra cylinder mount. Also, you'd have to put tanks, valves, regulator... on the robot. I'd argue that servos are a lot easier.
