Justice
Warrior
I used to think that mirrors proved who was the better player but after some thought, I think I have to tweak this a little. I now think that it proves who is the more well-rounded with a character. Since hovering in your ideal spacing is out of the question, fundamentals and mind-games are much more important. Mirrors also encourage you to use tricks, moves and tactics that are either outdated, "useless" or just not included on the flowchart of said character.
Let's take a simple example: the Sub Zero mirror.
Now two flowchart SZs will most likely hide behind clones until a time-out draw. Once one person decides to get brave and test the other's defences and knowledge of the hows and whys of cloning, then that player is far out of his comfort zone and forced to do things he's not used to. This could possibly even lead to learning new things about SZ in the process.
