Itachi doesn't need Genjutsu when he can just LOOK at Deidara and oenshot him with Amaterasu.

Keane has no counter to massive,crater making iron sand cubes.

Itachi doesn’t have any knowledge on the jutsu that Deidara kept hidden. I don’t even know why people keep on insisting that. Sasuke did not escape C4.

Itachi oneshots with any of his techniques, and there's a reason he was considered one of the greatest shinobi of his time, genjutsu or not. Garaa deflected it with regular sand.Itachis only hope against iron sand is life draining Susanoo. He can’t hop out of range if he doesn’t know what it is tbf. Hell, if Itachi can see it he'll instinctively know they're tiny explosives because they look exactly the same as his normal ones just smaller and less detectable. Itachi doesn’t even know about it. so he was a lot weaker than he would normally be. I don't remember if there's more examples against people. Sasori can manipulate his one hundred puppets from the air, supported by Deidara's explosive creations, to keep a constant attack going against Team 1.

AOE carpet bombs which would be harder to avoid and can damage Itachi if he doesn't have susanoo up,C2. @chair-sama: Can't believe this guy....lmfao....Itachi starts off with genjutsu like Deidara is gonna be standing their right in front of him looking in his eyes....lmfao....How about Deidara enters the battlefield dropping homing bombs flying high in the sky like he did against Sasuke.This wank is rediculous. A literal fodder samurai was able to survive a prolonged burning while in metal armor due to this fact.

He get a turned into tuna fish.8. iirc ,when he used it to break out of jiraya's toad stomach he was in quite a bad shape , not completely out of fight but quite tired and said that he will need some hours or days of rest to be back in full . It's not that fast. yep , if sasuke could do it, itachi can do it just as easily . Sasori and Deidara typically fight standing side by side, so they'll be in dispel range pretty much the entire battle.Sasori and Deidara are also both extreme long range fighters, and Deidara has the ability to fly and carry Sasori via his clay sculptures.

This makes Kisame a perfect counter thanks to Samehada. Burns slowly if it does hit and 3.) While Itachi can be beat by Deidara's C4 jutsus, that's if the fight gets that far. Itachi's only real long range attack is Amaterasu, which can likely be blocked by Third Kazekage's Iron Sand just as it's often blocked by Gaara's sand, and if Itachi tries to spam Amaterasu it'll make him go blind. And some of them are true since Itachi can use Susano that intangible to attack and cannot be destroy and also Kisame with Samehada which help heal him if he's wounded Sasori uses chakra strings to manipulate his puppets & himself.

They would both have to defend deadly attacks coming from all directions, even underground. Itachi is fast enough to escape C4 just like Sasuke did

It really wont, he has no way to take down Itachi and Itachi has the totsuka blade. Ama also burns slowly, so Deidara can take off his cloak depending on where it hits.

Assuming Deidara will be in range for Totsuka to cut him.

Amaterasu has a chance of tagging Deidara though as I said before it 1.) This is how he escaped. The problem here is that Itachi isn't Sasuke and Deidara knows how dangerous Itachi is and he might pull his cards. amaterasu would take care of his multiple puppets if they are used, on top of kisames giant shark bomb being more then enough to crack sassories armor. This is how he avoided the first one though. Be caught by surprised when there is no explosion from the big Deidara

Using it once isn't going to completely annihilate him. I don't know if he could even catch Deidara with Amaterasu.

Alright alright you won. Deidara is VERY aggressive and won't hesitate to blow himself or his allies up if it means killing his opponent.Then he retreats, Sasuke attempts another blitz and Deidara lets off a small bomb to cover a get away.

But this is just my opinion and is just one way of many he could win, but Deidara won't go down easy. LOOK at him. That required Sasuke to get into MELEE range.
