Your reward keeps increasing. I´m not sure but as far as i know your reward increases from x10collosus & x15missle strike to x10collosus & x20boulder strike. After that your reward becomes 1 skull nuke. The next reward then is x3zeppelin & x3 star battery. So if you train many friends you´ll reach your reward.
