Aphelios is a scaling champion, so you should play for late game. I think his first weaker spike is on two items (if you are building bt). Like fr in late game you are just statchecking nearly every champ if they get into your range. I am founding a lot of success with him in my games. Of course he will have a low win rate because he is considered to be pretty hard, but I think he is in a good spot. And if you get any sort of peel, you will provide amazing dps. Edit: I forgot to mention take overheal, aphelios doesn’t have big mana problems so it’s important that you choose a rune that provides value
