Depending on the opponent's DI, you may be able to hit them with a shine, turn around, and immediately aerial, sending them very far offstage.
“just back air instead
you can also aerial double shine
but like the shine bair is essentially just optimizing the DI in punish
gets you +5 damage for your bair basically
its a read that they will DI in but its also fine if they DI away cuz shine is good
but like if you KNOW they will DI away then just bair
but eveyrone [sic] and their mother will DI in there because if they DI away on a back air they will just die”

This is hard to execute and requires you to hit their lower body with the shine, but when successful, it has no real drawbacks.
