if its km naruto, instead of km naruto clone, then km naruto has v2 raikage level speed, and can summon at least 13 km clones, the same ones that beat the third.
We saw that against one km clone and its chakra arms, its almost impossible even for the raikage to avoid rasenshuriken. He's going up against 13 of them, and one real naruto who is even faster than he is.
One rasenshuriken has been shown to destroy the raikage's raiton armor and slightly damage him. Without his armor, the raikage gets shredded by attacks as weak as temari's wind net.
Naruto clone hits him with one rasenshuriken, raikage's armor is gone, and the next clone follows up right after. Raikage is obliterated.
