Graves

This guy can invade you from lvl 1 and will keep invading you if he knows what he is doing.Try to lay a ward down on his red and see where he started so you can adjust where to start so you don't fight for same crab or worst case scenario he invades and kills you.

Lee Sin

Same thing with graves but he just has way too much mobility. You cant fight him early because he can 1vs1 you pretty easily. Try to help lanes and look for objectives because lee sin players love to gank and you can sneak in rift or even drake while he is ganking.

Elise

Similar to Lee sin she is the queen of the early game. So much high dps, if 1 of her stun lands your health bar will get deleted early .Try to farm up safely and get other lanes ahead. Rack up on drakes and rifts and eventually you can get tanky enough that she will be useless mid to late game.

Amumu

Nothing scary about this guy until he reaches 6. His ult can be a game changer for his team. I would advise to look for ganks because Amumu players usually full clear and want to hit lvl 6 asap. Try to get any lanes ahead and dont let him jump in your backline. It can be very devastating since your carries will be dead if his teammates follow up.

Evelynn

Same as Amumu she wants to hit lvl 6 asap and will assassinate your carries from behind. Her early game is very week and she cant kill you alone. Punish her by ganking with your snowball and taking drakes. Eve cant do drakes alone until she has items or is extremely ahead. Lay pinks in tri bush since they reveal her in her passive after 6.

Hecarim

He can invade you can make you completely useless if you fall behind. His E cancels your snowball and his ult cancels your e and your ult. He can be very slippery and cna take objectives. Try to match him by counter ganking or getting bot lane ahead since a fed or semi fed hecarim can 1 shot adc's or control mages with his E. You are more valuable mid to late game since you can q+smite drakes and baron's. Also you provide your team abit more cc considering hec inn't in the fight. If he is running predator his is going to be useless late game.

Ivern

Farming jgler, try to gank a lot this match up try invading raptors and other camps of his since it takes a while since they are secured by him. Also do drakes and rifts and this game is a free win. Be careful of diasy's dmg and cc can catch you off gaurd.

Volibear

He can do everything as you but with higher dps. His ult can provide tower dives and can take down drakes easily. Try to get mid or bot ahead since voli gets tanky as later the game goes and your carries need the dps to burst him down.

Olaf

He will invade you lvl 1 and will keep up the pressure. Depends on his skill if he is tracking you or not. You can get solo killed by him and his ult provides him no cc which means your e, w or ult doesn't slow him down. Play for mid to late game and look for opportunities for objectives. Late game is all yours since you will get tanky and will out sustain him in team fights.

Kha'Zix

Early game jgler, will try to look for a full clear to reach lvl 6. Dont fght him 1 vs 1 because he just got buffs in his q and you will be isolated. He will deal dmg when he gets his items and his lvl 6 power spike is huge. Play around your teammates and look for dragon control.

Rek'Sai

Same thing with Graves, Lee sin and Olaf

Kindred

She will out scale you but you will have sustain. Try to catch her off guard with your snowball so your teammates can follow up. If she keeps distance she can kite you hard with her q and w and potentially kill you. Look for dragons and rifts early and try to get rifts ahead.

Warwick

Early game can be a real bad for you if he invades you, his dueling power is insane early on with q + fear. He will be useless as later the game goes but he can sneak dragons at lvl 4, ask laners to ward in rivers to see him and react accordingly.

Karthus

Early game very week and does full clear to reach lvl 6. You can invade his camps and get out before laners react. You can get drags easily and rift hearlds. You can also steal drags with q+smite and karthus cant out smite that.However his lvl 6 global ult can be devastating and can get kills. He scales extremely well, I recommend to build some mr or he can just pop you if you get 30% hp.

Kayn

In the early game he is useless, has no dmg to kill you. You can invade him and it will take him time to get his orbs to transform. He will most likely run red kayn which is a nightmare for you becashe his w and ult basically cancels your w and ult. He scales well and will heal alot. Build Bramble west and later down the line upgrade it to thornmail.

Trundle

He just got nerfed to the ground and his play rate droped significantly. However if you find a trundle in your game be carefull to trade with him, his pillar can trap you in and has great dmg. Look for ganks and drags when you can. If you fall behind you will not have a fun time against this troll.

Shaco

Sejuani

Tank that can make plays with cc just like you. Both of you should be fine but nunu can take drags away from her easily. I havn't gone against Sej in a while because no one plays her in solo queue much.

Vi

She deals alot of dmg and can ult you when you try to run away. Farm up and try to get laners ahead and place wards on drakes becasue she can solo them with ease. Dont take a fight you cant win in jg or anywhere, have team mates around you so you can cc lock her and hopefully she dies.

Zac

Same as Sej but abit more slipperly.

Shyvana

Very week early game but her ap scaling is a menace to fight against. She takes drakes the fastest with her passive dealing more dmg to drakes. Pink objectives and punish her by invading her early.

Rengar

A fed rengo is a nightmare to go against if the map is also ocean. Don't fight him in a 1v1 because he will destroy you. His ult can pop your back line. Get lanners ahead and take down objectives. You can sustain his dps when you get tanky.If he is on crab then just take the second one because he can just leap on to you and possibly kill you.

Jarvan IV

Same as reksai

Xin Zhao

Same as Warwick.
