Free Step Dodge

I'm sure KI had something where you could fight your own shadow. It's actually pretty accurate and fun.

I remember hearing MvC3 having something similar as well but was lacking the mentality to perform in situations where the odds are against you while being a shell copying the attacks/setups you do.

DOA is unknown, not sure if the game could even do that...may even be pointless at that if it had such a feature.

Though fighting against yourself (literally an actual human being who probably even looks like you lol) would be hilariously new because some of the stuff you can fall for is something you wouldn't actually complain about because it works and would do the same.

You'll probably hit the mountain point where you Vs a character/player you see so many times and just hold everything due to how the player is with the character. (Not saying everyone of course, people can play differently).

Being in a situation where you do the same with the exception of guaranteeds, if a player is holding everything correctly (except the CPU obviously) you can't really complain from that since the game's mechanic allows you to do that.
