Nice we get to see more of hiraishin.
Interested in what Minato said when he said he'd have to jump with it. Most likely to protect naruto/sasuke and take all the damage, or if he teleports he will automatically take it with him by default.
Also interested in what tobirama claimed concerning clones and hiraishin, its too vague. Whether only the clones speed of the jutsu suffer or the originals as well since, it must be chakra taxing.
What hit me the most is that tobirama claimed the last time obito attacked him he put a mark on him. I might be wrong, but after that, obito underwent a transformation which somehow erased minato's marking, so how is tobirama's marking left on him. Unless i am being told:
A. I am reading it wrong
B. plot
C. Tobirama's marking is superior
