This is just my theory for how they can win: if someone manages to get the deleter bullet out of Aizawa’s severed leg and shoot it into Shigaraki they might be able to win. I’m pretty sure he has more than one though.
There were 6 if I remember right. But I do not know if he has all of them or they were destructed when he awakened. ( ̄へ ̄)
What about giant dude lol
But the poison already spread in Aizawa's leg. I don't think there's still poison in the bullet...
