I'm sorry Mil, but you are seriously overstating Kojiro in some places.
1. Viltrification doesnt make him 100% immune to Mental Interference. If so, you're implying that his B+ skill is far superior to even Bravery A+
2. Knowledge of Respect and Harmony isn't "my attacks are literally unreadable", it's that the opponent cannot apply pattern recognition to his attacks. Saying shit like Instinct doesn't work is absolute bullshit, because that's exactly what saves Saber from him like half a dozen times.
3. Eye of the Mind (Fake) doesnt give you a free pass into looking at people's Prana capacity, Noble Phantasm usage, and so forth. You're trying to combine Eye of the Mind and a severely overwanked Discernment of the Poor (as in, DotP can't figure out people's prana, but by reading into people's true nature it might help him figure out that his opponent is trigger happy with their trump card), and it's dumb.
4. Average Yamato farmer doesnt have super-inborn anti-Mental Interference.
