Fizz

A very dangerous matchup, Zhonya's or Banshee's are required. Before level 6, if he initiates trades using his E and Q, use your Q first, then W, and Q again to trade as effectively as possible.

Kassadin

My personal ban. Kassadin is literally designed to counter mages like Aurelion. He takes reduced damage from your abilities, his Q interrupts your Q and W, high mobility allows him to dodge your E and R. The best you can do is start with Cull and farm while harassing him with autos whenever you can.

Yone

Yone is incredibly troublesome, being very strong in the early game due to Lethal Tempo. As Aurelion, you're forced to farm from a distance using your Q in the early game, which makes you stationary, and during this time, he can easily chunk a significant portion of your HP. You need to anticipate his Q hits and keep yourself very far away when his 3rd Q is charged.

Naafiri

Not as strong as release version, but still dangerous. Keep distance so she will not Q you. Try to farm her wolfs and if she all in, click W and DO NOT hold Q so you can keep distance

Qiyana

Qiyana is dangerous due to the amount of her crowd control, which makes assassinating you much easier. To win this matchup, it's crucial to position yourself well against her and maintain distance. Crown build would be Great

Zed

A lot depends on how good the Zed is. Certainly, Zhonya's is a must. Don't get within the range of his Q. It enables him to land his entire combo on you. When he approaches, similar to dealing with Talon, use your W to disengage. Harass him whenever you can.

Talon

Talon is literally the definition of an assassin, and those will always be an incredible problem. Talon becomes incredibly powerful as early as level 2 thanks to his passive, which deals massive damage right from the start. Play at a distance large enough so that he can't hit you with his W, and when you see him approaching to do so, move away using your W. Zhonya's will also be helpful.

Diana

Diana is a bit like AP Talon; she'll try to hit you with her Q, and once she succeeds, she'll engage and try to one-shot you. Keep a distance large enough to be able to dodge her Q; without it, Diana loses a significant portion of her damage. However, if she does hit you, maintain distance until her mark disappears from you.

Irelia

Be cautious against Irelia; her high mobility and how easily she can engage are the biggest threats. You can take First Strike against her and harass her. When you see her setting up her first E or starting to engage, immediately use W backwards to position yourself in a safe spot.

Akshan

Akshan will be terribly annoying. You have a greater range than his AA, so keep your distance and farm. When he uses his E to engage, use your W and disengage. If he's foolish enough that your W isn't needed, use your Q to trade back, and when he retreats, use W and Q to win the trade, possibly even get a kill.

Pantheon

Just maintain distance, don't let him get close for his W, take First Strike, build Zhonya's if they have more AD, or Banshee's if they have more AP. However, if he gets fed, build Crown."

Tristana

Tristana is an incredibly tough matchup, very aggressive and can zone-shot you quickly. In this case, maintaining distance won't help. When she uses her W, retreat using your W as quickly as possible. Ask your Jungler to stay close to mid to help you in such situations, possibly even securing a kill.

Ekko

Just like with Diana, keep your distance and don't get hit by his Q, and you should be fine. If he decides to engage on you without landing his Q, using only his three autos, use W in the direction he'll retreat, while continuously hitting him with Q.

Katarina

Katarina can be problematic because she quickly becomes very strong. In the early game, avoid engaging her, as she can easily out-trade you. Your W won't help much here because even if you fly away, she can stick close to you with her E. Outscaling her is the key, so if she's not too far ahead, she shouldn't be a major problem."

Xerath

Xerath is a typical artillery mage. It all depends on how well you can dodge his abilities. If he uses his stun aggressively, you can engage him using your W and take away a significant portion of his health.
