AY in v2 should have enough speed and power to stalemate hiruko.
True Sasori wouldn't be wasting his time focusing on Ay anyway, as he can fly. Flying will make Ay's Taijutsu less effective in this match up.
tsunade with her chakra enhanced punch should be able to break all the crystal release.
Using Crystal Release has not come to mind in this match up anyway. 3rd Kazekage jutsu will deal with her.
Mei can block sasori's line of sight by using mist release.
That will be useless as Sasori can use Ranton Black Cloads to even block the Gokages line of sight plus absorb their chakra it they pass through that huge cload it creates. The more it passes through chakra the more it grows. Not only that but he absorbed Chūkichi in these condition, which means he has the ability to sense chakra. Sasori has the advantage when it comes to block line of sight.
Oonoki prepares a jinton that hits Sasori and it's gg.
I am iffy on this one (if its true or not). If Dark Release has the ability to steal and adsorb KKG why not kekkei tōta? Thats in the air for me. But I am pretty sure it can use Meiton: Kyūketsukō then return the chakra back via Meiton: Jajimento
