So, I know you probably don't care, but I'm 18 years old person from Poland living in the UK. Played LoL since season 3 and stopped in season 7, then came back again in season 9. Pretty solid platinum player, I don't play with Ahri as much as I should've, but I mained her for some time in season 7, so thought why not start playing her again if I'm back to the game. Lot of you might disagree with this guide, so if you have any criticism or any suggestions to counters(Need more, don't get too many different matchups), or runes or anything else, just tell me. Also used to play dota 2 and a bit of hots.

Ahri gameplay isn't too complicated. Early might not be the best, but it's pretty easy to last hit all mage minions if you hit all of them with your q. Try to farm up to GLP and try to roam as much as possible. The slow will make it super easy to find free kills on other lanes. Just be careful as it can be stopped by any units like minions. On lane, look out for enemy jungler as you are pretty easy to kill before 6 or when your ult is on cd. Also, don't spam your abilities on your lane like crazy, if you are out of mana, that's it, your pretty much useless, so always keep some spare mana unless you are sure you will go back to base in a second. Try to get the carries as much as you can, as most of the time you can one shot them, unless they are super fed and they one shot you instead.

Didn't play a lot of games with ahri like most of the mains, therefore there isn't enough "data" for me to make this guide big. As I explore ahri even more, this guide will be updated as much as possible.
Hope you enjoyed, may you play well with my guide, cheers :)
