i am wondering if this would be legal;

a dueling organization in which i would give members tc to duel with. each member would have to make me a certain amount of tc in a time given. the members would also be payed (25% of their earnings for example) and i would get anything else. every time i give a member tc they have to treat it like a loan, so if they fail to make me a set amount of tc they can not duel for me for a set time and must make me the amount of tc i originally gave them in a week and pay me back.

it sounds kind of stupid but if successful, i could make a lot of tc like this without really doing anything. so would it be legal?
