Malphite can crap on any AD top. Vayne can out lane him from 1-5 because of knockback. The second he hits 6 you're done.
I'm going down the champion list and it's hard to find people that can dump on Malphite. Some APs like Rumble/Vlad crap on him, but he can just Gold Items and Farm on them.
Kayle is really the only AD who can trash him because her slow has longer range(slightly) and she can kite his ass with E/W. IF you can smart cast her Ult against his Ult it gets ugly.
