The first enemy hit, charming them and slowing them by 65%. So i want say Ahri good vs all midlaner champion with out Zoe because u can out play all midlaner champion so easy. Back to Zoe now, she have so much mobility thsi is why hard to kill her and she have too much DMG on Q and have cc to (E), Zoe, Ahris counter champion.
