I hear your argument and I agree with it. Here is the thing, so far @Sophia has been trying to take emphasis off of magic. Also, the way she has been describing the tournament, using magic is a disqualifier. (Andus hates magic.)
However, elsewhere in the thread, it has been hinted that the device used to detect magic will be altered in your match, Marxus’, or all of the above. So, magic will be used against you, even if you play by the rules.
