Lux

All you have to do is dodge her Q, because in late game she can easily one shot you. Even if she's not fed. I'd suggest you to buy Zhonya's as second item...

Yasuo

Yasuo is easy, in early and mid game. If he gets feed, buys magic resist items and tank, then you have no chance so all you have to do is poke him. Remember, that, a good Yasuo will use his W to block ur ult so Shunpo up to him

Ahri

Everybody knows that Ahri will ult for 2 reasons. 1) Run away 2) She's ready to kill you with gank. So, in first case , try to poke her and dont take her charm because when she does it, it's because of gank. Ignite is necessary vs her. In second case, try to not get the charm and shunpo to minions.

Akali

Ok, tanky and AP Akali are cancer. So you have to take void staf as second item vs her

Anivia

Many people forget that Anivia has the passive so they ignite her. Do not forget. Ignite her when she has not passive or after she rebirths.Try to dodge Q

Annie

Ok, Annie is hard enough...when she keeps stun it's usually because she's ready to kill you with gank. Flash and ult...

Azir

Azir is known as the second hardest Kat's counter... you can easily one shot him. The problem is his ult...so Q him E to him pick the dagger, the thunderlord will deal extra dmg. W and E him. Ult ,he won't get in time to ult. Ofc,build has to be right.

Aurelion Sol

Ok, Sol isn't hard, but not easy too. His tanky items may be hard for you to kill him

Brand

Personally I think he's a bit hard but more easy. Just dodge the second skillshot he'll throw you

Cassiopeia

Cassiopeia is very annoying. Low CDs, and ult that can stop easily your ult. And her W too....

Diana

Diana is known as Kat's biggest counter. When she E you, ult her, her E is the only that can stop your ult, take care ,ignite can deal zero dmg to her. Becuz of shield.

Ekko

Ekko is easy. Dont see him hard, try to ult when he does not have ult.

Ezreal

An adc mid...well...the only bad, it's that his skills have so much damage with AP items. Dodge them.

Fizz

Fizz has so much damage...especially if he builds lich bane...I'd suggest to buy Zhonya's first item, because of ult. Stop his ult and he's zero

Galio

Shield...ult...tank...take care of teamfight. Do not go close to him. He will try to focus the whole team.

Heimerdinger

Ok, heim is annoying, everyone knows this. Kill his robots in early, and dodge his stun.

Karma

Getting hit by Karma's Q in Mantra or not, hurts. Poke her, so she'll be killed easily.

Karthus

An easy lane. Zhonya's is necessary in late game.

Kassadin

Kassa's Q can stop ur ult...he can run away from your ult with R. You can cast3 Shunpos, so ...it depends
