Bel'Veth

One of the hardest matchups. You want to avoid 1v1ing her at all costs, usually play opposite side of her, respect her invades, only play to fight her with your team having prio and helping you, make sure you know if she used her E or not early, cause she can block all of your burst with it. After form you should be fine against her though, still very tricky matchup, she can dodge your combo with her dashes, she can eat all your burst with her E.

Lee Sin

One of the hardest matchups, super strong early, decent camp clear, insane gank potential, runs a tanky build mid game where you can't oneshot him even if ahead. Generally, dodge his Q's early and you should be fine, play around your team and their prio to help you, otherwise respect his 1v1 and invades, after form you should be fine, but he'll still be hard, can kick you away, tanky, and he can be annoying for your team.

Master Yi

Super hard matchup, Can dodge abilities with his Q, can eat your whole burst with his W, has a very good clear speed, strong early 1v1 even if ahead. Generally look to avoid 1v1ing him, either counter gank him, or play opposite side of map from him. You will still struggle with him mid game cause of his w and q, being able to dodge your whole combo, so play around your team stunning him, and then use your abilities.

Rengar

Rengar is my permanent ban, this matchup is very annoying, he can heal your whole burst throughout the whole game with his W. He can invade you whenever he wants, and your mobility is nothing against his due to his bush jump passive. he can just stun you and your e is useless, he can jump around with your q's, has insane burst and early dps. has insane counter gank potential to you, cause he can camp bushes and just lock you down with his team if you want to gank. Generally I'd ban him, but if you want to deal with him, just don't face check bushes unless with your e, so you can have the Dot indicator that he's there, avoid him early, never look to fighting him unless you have form.

Rek'Sai

Not the hardest, but defenitely a hard matchup. Look for power ganking opposite side of her, or counter ganking her, she will always look for level 3 ganks, ward for your team, and ping them, or just go there to counter gank if possible. Avoid 1v1ing her, she's 10x stronger than you early, you will need edge of night in this matchup for sure. After form you should be fine though.

Udyr

Super hard matchup, he's super tanky throughout the whole game, even with form you will barely touch him. Has insane mobility, gank potential, fast clear, good objective control. overall, I just avoid Udyr throughout the whole game, and play oppositely, get form, and keep forcing on backline, play for your botlane, cause usually your adc is the only one that will be able to deal with him.

Xin Zhao

Annoying matchup but you outscale, you have faster clear, he has good gank potential and decent early/mid game, just respect his early, and his Q knockup locking you down with his team, and you should be fine.

Wukong

Annoying matchup, but you outscale. He has decent clear, his jump and W can be annoying for you to land your abilities, his passive gives him a lot of arrmor which can make you not able to one shot him. His knockup can be very annoying aswell. But generally after form, you should be fine.

Amumu

Ekko

Diana

Evelynn

Whoever gets fed in this matchup, ends up stomping, but, you can play it properly and kill her, using your e to give vision on her, and fast combo to one shot her and get the shutdown.

Fiddlesticks

I would say fiddle is a matchup I win most of the time, but he's annoying nonetheless. I would say you can easily predict his next moves, since he follows a full clear almost every game, and camps for ults, so with good vision, avoiding dumb fights where you will get 5 man ulted, you should be fine, also buying edge of night helps, and avoiding him and going for other squishy teammates.

Gragas

Graves

50/50 matchup, he gives you blue orbs, but punishes you early with invades, just be smart and avoid his invades if your team can't help, and invade opposite side, I usually split map against graves players till I get form, then it's easy from there.

Hecarim

Generally easy.

Ivern

This one is a tricky matchup, you need to learn how iverns path, they usually put their passive on wolves, blue, gromp and go to their botside then go back to their topside and look for a level 3 gank. You can even spectate them to get a better idea, Just make sure they don't invade your camps, and if they do punish them back, and look for either playing opposite side of them, or counter ganking them, ivern gives blue orbs aswell, so its a 50/50 matchup I'd say. Very laners reliant.

Jarvan IV

Jarvan has the upper hand in this matchup, his clear is very good, his mobility is really high, his early ganks are insane, and his midgame burst and tankiness is just unmatched. Generally he's like a tank you can't match throughout the whole game, so I'd just play opposite, get form, ignore him and play for backline flanks, unless he's too behind and I have cc on my team, where we can lock him down.

Karthus

His clear is just insane, he'll never be useless, but it's 50/50 cause he will give you alot of orbs, you can punish him in correct situations and he can't kill you back, and even if you fall behind, most of the time you'll still be able to one shot him and his team.

Kha'Zix

I'd say you have the upper hand in this matchup if you're a good Kayn, just avoid facechecking him early, track his pathing, respect isolation, play for form, once you get form, even if he's 5 kills ahead, you can oneshot him before he oneshots you.

Kindred

50/50 matchup, she invades a lot, very good early, can punish you, still gives you blue orbs, if you counter gank her, or make her face check you, you can play around that, basically respect till form

Lillia

Gives blue orbs, but very annoying and fast, builds zhonyas, tanky builds with a lot of HP aswell. I would generally say a good Kayn wins her, but it's a skill matchup

Maokai

Can be annoying with his sapplings delaying your E, he's tanky, pushes you away from your Q animation, but still, can easily out farm him, out gank him, and out impact him after form by killing his team, he can't stop you.

Nidalee

Some people find this matchup hard, I would say it's annoying, but if you're a good Kayn, you'd outscale and win a Nidalee 9/10 times. Respect her early, play really aggressively oppositely to get form asap, after form, you should run her over.

Nocturne

Annoying matchup, but you out farm him, out gank him early, have generally more impact, just in long 1v1's he's better, you can still oneshot him once you get form, only thing that's annoying is his ult blindness, you can buy edge of night for that though.

Nunu & Willump

easy

Poppy

Ugh, that word simply describes this matchup, very annoying, positive side though, you will outfarm her, generally I'd ward for my team against her, avoid her cause her whole kit counters me, invade her and power farm, and play for opposite side, then once I get form, I'd be like 2 lvls ahead, and stomp her team. Generally never all in on her, or even near her, play around walls and flanks to the backline.

Rammus

Generally easy, he's a tank, you win him early in every aspect, then if you get a lead, kill his whole team, you should be fine

Rumble

He has decent clear, annoyingly strong early, but you generally can get away with it early, and once you get form you're fine.

Sejuani

it's a 50/50 matchup, generally you'd be stronger, but she's really annoying, with alot of cc, and if she has winning lanes, you can't play much around her, I'd only take secured fights against her, get a lead, avoid her cause she's still a tank, and just look for destroying her backline.

Shaco

Shaco's are generally easy, just respect ad shaco's burst with ignite, and sweep against ap shaco's boxes, and you should be fine throughout all the game.

Shyvana

easy

Skarner

Thank god this pick is not meta, this champion is insanely strong against you, has insane clear, insane objective control, annoying amount of cc, and he's super tanky, with alot of damage, godbless hes not picked alot xD

Sylas

Zed

Zac

You can control the game by power ganking before he scales, but becareful of getting baited by his aggressiveness when he has his passive up, generally you play it like any other tank you play against, you out impact them early, out farm them, then get form and ignore them all game

Warwick

Volibear

Viego

Easy matchup in my opinion, this guy doesn't have anything better in his kit, and even if he's 5-0 early, once you get form, your team can easily cc him down, and you can burst one shot him and get shutdown. You might struggle if he buys deathdance 3rd or something, but then you simly avoid him.

Vi

Talon

Better assassin wins. Gl

Taliyah

Easy, she gives you free form, easy to abuse, easy to counter gank
