[HMM V OFF TOURNAMENT] "Wise Hero"

I'm signing up, but I have a couple of questions: 1. What's with the final battle? Isn't this a tournament where the goal is to defeat opponents, not necessarily enemies? Maybe it doesn't have to be on the last day, or maybe it just means the last match? 2. Why can't we use Astral Gates, Subjugation, and Mentorship (Mentorship is understandable, but I don't understand why not the spells). Well, let's see... I'm aiming for first place.
