This should be re-named a fodder with abnormal breasts and a non-fodder and a snake who needs more screen time vs An Akatsuki Member.
Just because.
They aren't going to instantly blitz him, Hebi Sasuke is faster than both Tsunade and Jiraiya, Orochi is debatable but to move at speeds like such, he needs to turn into his snake slithering mode.
Deidara will begin the fight jumping back, using the C2, summoning the bird, or making clones to implant C1.
Summons are countered by Deidara's large flight area and their lack of flight, Deidara is far faster than all of their summons as the bird was running through the entire village of Sunagakure in not even a minute's time, while dodging at that.
Using the strategy he used against gaara, he will use his flight to store up clay for 2 options.
C4 or C3, either one works.
C4 might be the more liable one here seeing as it decomposes you at a cellular and even molecular level, countering both Byakugou, Orochimaru and Katsuyu.
C3 was able to take out more than 60% of Sunagakure, they aren't tanking it, once he drops it on them at point blank or suicide bombs it with a clone.
C2 is also Liable for ground combat if he is somehow grounded, and should effectively counter out taijutsu, rasengan and hidden shadow snake hands, all the while C1 bombs are being planted if not already there.
