Which AP mid champion vs tanky comp ?

Hi everyone ! Here my first post on Reddit so please be nice with me .

You have the question in the title. I main Syndra (top 200 EU), I really love to play with her but I have a problem : tanks.

When I play against a compo with at least 2 tank my game will be hard because even if I build with item to match, I don’t have enough damage to kill them, they just have to run on me, I can’t do anything (unless if I have a very good early game). For those who say that my goal is to kill the squishy ones, even if I manage to kill one, there are still the tanks to kill that are running at me.

So I’m looking for a new champ to play when there are a tanky compo against. I particularly like play mages.

I look forward to hearing your
