I have been wondering ever since i passes 600 000 SP and start getting support style, what they are for???? All the characters u get before 600 000 SP u can sue the for supports, so what are the ones that show up after unlocking all characters???

Also another thing is about substitutuions. After each boss battle a new substitution style unlockes and then u can sue them in free batlle, but do they do?

Can someone answer to these questions plz? I would appriciate it.
