Karthus

Has no mobility and you can easily dodge his abilities. If you charm him before he ults, his ult will not go through. You may get hit with a few of his q's but don't worry about that, you can all in him when you're level 6.

Aurelion Sol

He uses a lot of mana pushing in lane, you can charm him if he's trying to q you and if you charm while his stars are out they will be forced in. Push him under the tower, he can't cs under tower well.

Katarina

Don't stand near her daggers, you can dash out of her ultimate or you can charm her out of it. You can harass her early game.

Fizz

His ultimate prevents you from going far with your ultimate if it connects. If he e ins to try to kill you then you can charm him. Make sure you're not low or pushed up without help unless you're ahead.

Malzahar

You can easily remove his spell shield. His little minions can block your charm but you can charm him out of his ult if you use it before he ults.

Zed

You can dodge his q's with your ult. Remember his cooldowns and check his energy. Don't stand too close to his shadow while you're low health or he's level 6. If he wastes w you can go harass him pre 6.

Taliyah

She plays pretty far back, try to stay behind minions and harass. Watch out for her w.

LeBlanc

Skill matchup, try to harass her and when she goes in with her w charm her and use your abilities.

Akali

I can't really say, I haven't played against it. Don't waste your charm and don't try to land it when she's in her smoke unless she comes out to q you. Your w doesn't hit her while she's in it but you can still q.

Veigar

He usually stays too far back or you to hit him and if you walk up he hits you. You can't ult out of his wall, build banshee's and zhonyas.

Xerath

He's a squishy champion but he has long range and lot of poke, his passive allows him to get mana. Try to stay healthy in lane and watch out for his w. He would typically want to q you and the minions so don't stand too close to them.

Ziggs

He isn't much of a problem, all of his abilities are skill shot abilities. Just dodge his abilities and you're good. He does use a lot of mana early, if he tries to auto you with his passive charm him.

Twisted Fate

His harass in lane can be a problem, not hard to out harass him though. Try to hit him when he's using a card other then yellow. Always ping when he's lvl 6.

Teemo

Anivia

You can ult over his wall and away from his long range q. Don't forget to not kill him while he is under tower, he will just get all of his heath back because you can't kill him while he is an egg. His ult does slow you and increases the power on his e. He has a hard time pushing/farming pre 6 though.

Kassadin

He's supposed to be a mage counter, hit him when he doesn't have q and his ult costs more mana the more he uses it.

Swain

Too much cc and healing for ahri to burst down. Try to dodge his e and you should be able to fight him each time.

Gragas

Watch out for his q, full ap gragas does a lot of damage and can one shot ahri. His q is easy harass and he gains health back with his passive. You can watch panunu for this.

Azir

Watch out for his soldiers, shouldn't be a problem to fight him post 6, don't get too close or use all of your dashes trying to get close to him. He is squishy and should not be a problem for you. He will might likely stand behind minions so poke with q.

Ekko

Melee assassin, he does a lot of burst damage, try to charm him when he uses his e. Most ekkos use e+q at the same time, if you charm him you can dodge the second part of the q.

Yasuo

His windwall can block all of your abilities, try not to fight him when it's up. You can aa his windwall off and try to poke him in lane.

Annie

She has a lot of burst damage, try not to fight her when she has her stun up or 1 away from stun.

Brand

Extremely long range abilities, can easily out poke you. You can dodge his q easily after 6 if you're not too close. He does a lot of damage.

Vel'Koz

You can charm him out of his ult and and dodge his combos with your ult, should be an easy lane for you. Don't waste your charm.

Talon

Land your charm when he jumps on you, if he ults you ult away.

Diana

Diana is another very hard matchup for Ahri due to her having quite high burst and being able to stick to Ahri easily with her own dashes. Play safe and try to dodge her Q's, she can farm and harass you with it. Save your charm for when she dives onto you.

Heimerdinger

This match-up shouldn't be hard, you can kill his turrets with your orbs and you can dodge every other ability easily. Your charm does hit his turret so watch out for that. Only problem against him is his turrets, destroy them and you can beat him. Note this doesn't mean always focus on the turrets.

Galio

He has a magic shield and his e reduces damage. He is a melee champion so you can easily harass him in lane. You probably wont kill Galio but you should get a void staff or you can just build the items I recommended. Roam often because you have a low chance of killing Galio.

Cassiopeia

She does a lot of damage with her e lvl 1 (needs to be lowered). You can't use your ult in her w and you don't want to look at her when she's 6.

Syndra

She too far back for you to harass and if you try to go in she can knock you back.

Lissandra

She cc's you a lot, mobility is your strength and that's what she prevents. Bring cleanse and watch out for ganks.

Lux

She stays far back but doesn't do a lot of damage without items. She runs out of mana fast if she spams abilities, try to dodge her q so she can't combo you.

Aatrox

Irelia

Damage reduction with her w and it can not be stopped when you charm her. She slows and disarms you if she hits you with her ult. Hard matchup, all you can do is poke and not give her a major lead.
