The Fourth Raikage. All of Deidara's bombs would be ineffective, and he'd resort to blowing himself up, which would also be ineffective.
Remember, Blast Release is weak against Lightning Release.
Oh really?bullshit. only earth release is. If deidara can explode his bombs before ay uses lighting on them, he wins. Ay is stupid. Deidara is smart. He'll outsmart him.
Deidara wins. mid/hi diff.
