Well I won't go against you saying your decision is wrong, and I understand now that you have it under surveillance :) I was just concerned when I read the cs that it seemed very depending on wording for effect. And very dependant on having either smart opponents or at least two of rather simular strength. But it also don't point certain things out... Like if he was going to fight his powers limit to the strongest opponent... But dosen't specifify how it does so. It sounds like an effect that could be misused as long as he can just select any target 'player wise' as the strongest opponent. Like he fought against anyone and select the headmaster as an oppont to rise to his strength. Steam roll any student and abort before assaulting the head master. Ans his strengths seem to be slightly more than his opponent, meaning if someone could destroy an mountain he could do the same as long as he fought then. With his un magical fist. But that can just be me understand it incorrectly.
