Mistu isn't that broken IMO. He's linear from long range and his mid range comprises of quick pokes. You may eat a little bit of damage from 2 wrong guesses but you really shouldn't be getting launched that often or eating predictable 2k BEs. Don't even worry about the sweep til he has at least a bar or 2. His mist stance is taken care of with 6a+b and smart backstepping and ducking cause all his tools are either high or slow in that stance.
If you have good throwbreaking skills and patience the fight is definitely winnable.
