They destroy landscapes, but the Kunai will only be moved, nothing more nothing less. Minato's ST barrier can still be used.
Naruto isn't moving at any super high speed when in the Kurama Avatar, and if he isn't in the avatar, he gets shitted on with ease. Take your pick cause you can't have your cake and eat it too.
-Scans of these giant Enton Magatama? Oh wait, you have none.
Cause the Buddha is only 17 feet in length amirite?

Stop. Not to mention he literally only has to open the barrier in their line of flight, and they'll soar right into the warp hole.
Minato can sense chakra in BM, and can move his teammates around via Hiraishin as long as they are marked or connected to his chakra. (Which he will do) So uh....Kamui is avoided by Hiraishin. With ease.
Naruto redirecting standard Bijuu Dama doesn't mean he can do the same with Bijuu Dama which are the same size of his own, try again. Madara's PS has no feats to let me believe it can smack away Bijuu Dama, especially one of the sizes Minato can make, which are equal to BM Naruto's.
Kamui=/=Amaterasu, so no. Unless you have some proof, it won't be at such a size.
Bijuu Dama blades inside of rapid fired Bijuu Dama took out Shinsuusenju's hands at the cost of PS being broken open. If he throws the PS's blades, they will move much slower since I have seen no feat from PS which lets it throw its blades as fast as a Bijuu Dama moves, nor have I seen
Shinsuusenju is bigger than the Juubi, your point? That was merely the size of Chou FRS, which rivaled Gamakichi in size, who isn't even the size of a full Bijuu. Shinsuusenju still plows through it and busts open PS.

-Gonna need a scan of him using an FRS the size of the Rasengan Minato used.
-You act like it matters. Shinuusenju was able to snatch up Full Kurama in its hand, that Rasengan was smaller than BM Naruto and BM Minato.....who are smaller than Full Kurama. :| Please stop wanking Naruto.
-Nothing is stopping Shinsuusenju from continuing its punches uninterrupted since they have no way to take it down.
They can warp away, but its counted as BFR since they are leaving the battlefield, and he's not going to be able to warp both of them before Shinsuusenju and Minato's BD finish them off.
