I want to adress few things:
Pain wins this
1-By hiding in his chameleon, he can camouflage himself and go invisible
2-By going aerial on his bird, he can avoid close combat
3-Correct me if I'm wrong but Team 1 has no way of taking down Cerberus
4-Asura missile spam eventually takes down Tsunade since she cannot regenerate indefinitely
5-Human Path can rip the souls out of them
6-Preta Path can absorb Ay's lightning cloak
7-Chibaku tensei
1) Byakugan sees through it.
2) Guy can jump on his turtle and take it down.
3) They don't need to, they need to take down the source of summoning. Rashinsho potentially takes it down.
4) She does not need to stand in its way, those missiles are not particularly fast (Chouji could outrun for some while). A wrecks it anyway.
5) With manga intel they will use distance attacks.
6) Theyhave intel. Even if it does, his chakra levels are high enough to have a new cloak or Tsunade refills him.
7) Restricted.
OT: Team 1 would win boths scenarios. Tsuande and Gai make an OP combo from the beginning adding A who can one shot some paths with his speed and Hiashi who has byakugan insight ensures victory. Second scenario is similar, Katsuyu acid or Lee/Gai's asakujaku takes down Konan.
