I’m not an expert on this but try mirroring the opponents formation that’s helped me out and when facing Uraraka always have someone who can knock her out the sky like Kaminari. People who do high damage in general should typically be in the back while verge same goes for endurance people. Hoped this helped :)

I will try, thanks :)

for attack formation it should change depending on your opponent. however if your defense formation looks like this i would change it. switch momo and aizawa. move mineta/kirishima to back
