No prep-time has been pretty well covered, he can take the folks at or just above peak human, including Cap and Winter Soldier. Panther's suit might be a bit too much for Batman's regular arsenal to handle.
With one-sided Prep-time and the first move, a lot of it would be the same kind of BS from Tower of Babel, exploit weaknesses and or try to disable/contain the ones he can't beat.
Hulk: get him in a room and flood it with enough "happy" neurotransmitters to bring him out of hulk (or keep him from changing) and lock him in there.
Iron Man/Warmachine: try to find an exploit in the armor? Warmachine's the easier of the two but Stark's newest suit might be impossible to deal with
Spiderman: Ethyl Chloride, his own version of kryptonite that can shut him down hard
Vision: Electricity might slow him down (at least in Civil War) though it becomes a matter of using enough to trap him without letting him blast his way out
Thor: Making him unworthy wouldn't be enough since he'll still be to strong and fast to contend with, probably go the Wonder Woman route from Tower of Babel and use hallucination inducing nanites to keep him fighting illusionary opponents forever because he has no real way to actually beat him
Black Panther: Electricity?
Ant Man / Wasp: Assuming he can't create a counter to Pym Particles, best he can do is try to lead them into a trap/containment field.
Scarlet Witch: He has one shot to take her down while unaware before she mops the floor with him
Quicksilver: His plan for the Flash actually worked so this one would could be prepped for
Doctor Strange: Good luck, unless he can find some form of magic immunity, the best he can hope for is a one hit KO with complete surprise.
With prep, he might be able to take half the ones he normally couldn't, but that's with stacking him with the first move advantage and one-sided prep.
