Just gotta quickly chime in on this one.
Mirror matches have never proven who is better with the character.
Definitely true. I would (in my personal opinion) consider Madzin to be a better player than Tom but my money would 100% be on Tom in a sub mirror with literally anyone. His patience with sub is his strongest skill and that match is all about patience. Remember the Tom vs DJT mk9 mirror match with triforce commentary? DJT is pretty much without a doubt a better player than Tom but Tom wrecked his day in the sub mirror.
