A Deidara employing physical traits isn't quite equipped to battle a Shinobi who could bypass his physicality via Air Palms, 63 fists, 82 palms and the likes.
it’s just a very bad match up for Neji, all the Taijutsu in the world still won’t match those bombs. Deidara is seriously underrated in general and is definitely one of the most original characters to me.
Agree on Deidara being underrated. Doesn't prove anything in this thread though.
You need to prove how his specific strength relates to Neji. How it beats him.
Air Palm already dealt with the ground specialist Kisame, who is a specialist compared to Deidara, so there's no reason Deidara will dodge it. In fact, his anti-genjutsu strength is a weakness here because lack of chakra-vision (from a natural eye) means even the big hits Neji preps will be undetectable (when chakra is strong, it becomes dense enough to be seen by naked eye) or at least half as detectable. So Air Palms hard counter Deidara.
