Despite being more technical than just mere power, Tohno would fall prey to Tezuka's Hyakuren. Hyakuren can double everything, and Tohno's executions are no exception. I see Tezuka returning them and I don't think Tohno can overcome his executions back at him with twice their normal strength.
If Chitose could use Saiki in doubles, and it'll be possible because that weakness needs to be overcome at some point, he could see when Tohno's going to hit one of his executions. Also, Tezuka Zone should work on them.
Ochi will score past Chitose with Mach, but Tezuka should be able to comfortably return it. Moreover, he has his Mental Pressure, but Tezuka will overcome it eventually.
