Amumu

He can't really kill you if he fails his stun, and if he gets you, you're able to escape if his team does not follow him up.

Elise

Skill match-up.

Evelynn

Try to get aggressive on her every time you can. If she falls behind hard, then she won't be able carry late game.

Gragas

The first getting hit by the other's stun usually wins the trade.

Graves

Long range and high damage, but don't forget you're an assassin, just let him ay his early game, here you must be concentred on late game where you delete everyone.

Hecarim

It's difficult to play against since he has good escape, damage and engage at every stage of the game.

Ivern

Steal his blue and he's useless. Just try to get 1v1s on him as you will most likely win if his team does not show up.

Jarvan IV

You can easily escape his follow up combo with your Rappel and kill him after.

Kayn

Rhaast is a problem, Blue Kayn is a problem, so you MUST get kills on him as soon as possible to get ahead enough so he can't 1shot you later or CC you to death.

Kha'Zix

If you land your Cocoon, you win, if not, get on your spider form and his damage will be halved.

Kindred

Another ADC jungler... let her get her early game, focus on getting feed on the other side of the map, since she can't kill you there :)

Lee Sin

How annoying is his kit? Try to dodge his Q moving or his 2nd activation with your Cocoon or Rappel, then you'll be fine to escape or kill him.

Master Yi

You have the early game priority, he has some troubles with his first clear, get on him there, if you kill him 2 times, it shouldn't be a problem anymore.

Nidalee

Has lots of damage, dodge her spear and all-in her at all stages to win.

Nocturne

Skill match-up. The first one geting CCed loses the trade normally.

Has lots of sustain in the jungle. Try to group with one of your lanes to kill him easily, but DO NOT CHASE HIM! NEVER!!!

Rammus

After 6 you can't really kill him anymore, just try not confronting him if not 1v1 at levels 2~5.

Rek'Sai

You can't kill her alone without your Cocoon, and even there, she might kill you, so try to get her low before all-ining her.

Rengar

Same as for Kha'Zix. Hit your Cocoon to win, use Rappel to dodge his first on you from a bush.

Shaco

Difficult to kill, difficult to chase, difficult to escape from... you should never 1v1 him unless you know 100% there are no boxes near you or he has already used 1. Try to camp him in his jungle.

Shyvana

Versus Tank Shyvana, try to not 1v1 her. Versus AP Shyvana, try ti not 1v1 her, usually you'll win 2v2s but not 1v1s, since she has more damage than you but it's single target.

Skarner

He's pretty bad without his crystals, so try to confront him without them around or controlling the nearest one.

Udyr

Never 1v1 him, you'll always need someone else to kill him, he has a very good kit to deny every assassin potential.

Vi

Try to 1v1 her at level 2, you can clear yoir jungle with more ease and you're a lot stronger then. If not, you can try ti steal her scuttle and kill her with your health and mana advantage.

Volibear

You can profit of his bad early game to kill him as often. But be careful about his team coming to help. In mid/late game you won't be able to 1v1 him.

Warwick

As Udyr, NEVER 1v1 him. He can easily get you low and heal up your damage.

Wukong

He can't really kill you, but can escape with ease, so try to wait for him using his invisibility before landing your Cocoon and killing him for sure.

Zac

You can't really 1v1 him, so try to counter jungle with your mid-laner and to get deep wards on his jungle to avoid his long-range ganks.
