Rasen Shuriken wouldn't get to him. We've seen energy based attacks are still aged. Amaterasu shouldn't reach him either. It doesn't last forever even if it does last a long time. And even if it did Baraggan can still side step it easily with time dilation. Genjutsu, well i don't know if Sasuke will have much opportunity to look into Baraggan's eyes......who has no eyes in release. And on top of that, genjutsu is performed I believe via the user distorting the victim's chakra with their own. Once again I'm not so sure that chakra will even get through a respira. A biju dama is the biggest problem, but fortunately for Baraggan, it does not explode until it makes contact which it won't due to his time manipulation, and given that he fights in the air, it couldn't even explode near him.
