Can Deidara counter Tsukuyomi ( Itachi's ) ?
We all know Deidara trained his left eye to see through genjutsus.
I say no :
1- He is not immune to ocular genjutsus. He sees through them.
2- Tsukuyomi is near instant, as evidenced by Asuma's words : one second Kakashi was fine, the other he was almost K.Od
So I say, Deidara can potentially sees through it but that hardly matters because 1 second is all Tsukuyomi needs.
You agree or disagree ? Say why!
*Don't flame, I was just wondering if he trained for nothing. But hey he still has his nano bombs
