[@Deluge] Alright, one thing that springs out immediately is that you have second years in your top 5. First and second years have their own brackets separate from the third years, so while it may very well be possible that some second or first year duelists are better than your top 5, officially they wouldn't be in the top 5. Considering the winning dorm's top 5 students all go pro if they win, it'd be awkward for a second or first year to end school early like that.

EDIT: Or, y'know, what Sat said.
