When you enter into a battle, it will be between either you, another trainer and an updater, or it will be between you and an updater. The updaters will be the ones to conduct the battle. The only thing you have the power to do is to decide which commands and which Pokemon to use. The updater will determine the damage using Pokemon levels and attacks. If you feel you should have won a battle that you lost, you may contact me and I will review the battle.
This keeps the role-play fair, since many people out there will be unfairly invincible and will dodge every attack and catch every Pokemon on sight.
