As others have stated you really just need to stop Hashirama from getting his barrier up to beat most Hashi teams. Unless the Hashi team has drastically more power then you stopping his barrier should reduce the damage you take enough to get by (unless you're lightning main). Ao is a good pick since he can't be stopped by their Iruka. Doesn't matter if you cant outspeed their naruto, just eat that damage and stop the wind main from using their mystery in round 2 and it should be over.
