Rip Hunter, Time Master Vs Iron Man (Stark)

Both characters get an equal amount of prep.

vs

Rip.

Erm..

Ok, Rip has SOME fancy future tech, but I don't see him as the sort to show up on a battlefield with loads of fancy tech, right?

So with prep, won't he just use time shenanigans? Which is an auto win?

He did against the Hyperfly, right? Multiversal level being, too.
