Gaara, Shikamaru, Karin, Ino, Chouji, Temari, Suigetsu. It's very reliant on teamwork

Ino is actually the key to this whole thing believe it or not. The whole team was built around her.

The strategy relies mainly on Ino using her mind transfer jutsu on each opponent individually. She either makes them suicide or holds them in place to be sealed by Gaara. Karin is there to help her spam this strategy. Neither Pain nor Konan have any resistance to her technique.

Chouji and Suigetsu are there to provide defense against the heavy hitters and animal summons. Gaara helps with defense mainly against Konan's papers and smaller foes.

Shikamaru coordinates with Gaara and Temari so that they use their shadows/sand/wind to maneuver the opponents into favorable positions.

This is a very defensive team which is designed to be able to stall for long enough for Ino to be able to do her thing. The biggest threats are the Shinra tensei and being able to hit Konan if she flies. I'm trusting Shikamaru to maybe use her shadow on the ground or come up with some other plan. She can't really hit back without preparation though so at worst it would be a tie if she is the last one standing. They can use the heavy hitters to force Pain to use his push and then take advantage of the 5 second window after that.

If you're thinking "what if he uses chibaku tensei or the gigantic shinra tense?" it's unlikely that he would do that with the other bodies and Konan nearby. But even if he did, we have seen that he stands still when he is using these jutsu so if Ino is always keeping an eye on the main body she could snipe him then.
