Lol no it's hard to figure out your own student when he has half of Hashirama's chakra/body and Madara's chakra/ eye running through him.
And Kakashi's sharingan can all of a sudden see through clones? Lol.
The only reacting require for FTG is thinking/brain.. No physical movement is needed for reaction while using FTG after the kunai is spread.. again decent level ninja can use FTG effectively If they know the jutsu.
Lol. Which have defeated more opponents, exploding clones or genjutsu.
1. Exploding clones = 0
2. Genjutsu = thousands
Save the BS.
"Which have defeated more opponents, exploding clones or genjutsu."
Genjutsu alone : barely any
Feints : too many to count
Genjutsu thanks to feints: plentiful
