You're only stating Itachi's jutsu (which I'm well aware of), but aren't validating how they'd affect Deidara. You can't just say, "Ohh, Itachi has long-range tech's too, so he'd win". Do you not realize how high in the sky Deidara was when he fought Gaara? There is no tech Itachi could hit Deidara with other than Amaterasu (I've already stated how Deidara could counter Itachi's Amaterasu) if Deidara takes flight with his bird. Also to whoever said Deidara is incapable of planting his bombs, during his fight with Itachi, he made a centipede, allowed it to travel under the wood floor, and sprout up and wrap around Itachi (I'm aware this was in the genjutsu, but it proves Deidara can create clay creatures that can burrow underground). Like I said, give it up. Accept the fact Itachi isn't invincible and can be solo'd. I'm not trying to diss Itachi in any way, he's a monster, but you all are just making claims and not backing them up.
