Gnar

He can kite you extremely well . Be carefull and never pick Orn into Gnar.

Cho'Gath

He can outpoke you and push faster than you . Most of the time a good Cho will establish lane dominance.

Darius

Never fight him alone and try not to do so early , you scale better than him so wait for your powerspikes.

Dr. Mundo

His Q and passive are really annoying to deal with but a little help from your jungler will trample him.

Garen

Be afraid of him if he goes attack speed , if he goes for a tank build just be patient and scale .

Illaoi

Dont fight her if she has a clone from her E , she will heal back a lot .

Irelia

The Irelia matchup is not good but not bad , try to freeze the wave in your side and then ask your jungler for help.

Jax

Try to poke him down and then go for an all in when he has no E.

Kled

This guy is like fighting 2 people at the same tome , untill he gets nerfed play safe and try to hold lane , not win.

Aatrox

if you stick up to him and dodge the outer parts of the first and second cast of Q then you can start slapping and poking him .

Malphite

If you poke him back eventually you will scale off better and then you may be able to get a couple of kills on him . But be aware of his R and keep vision in the river bush .

Maokai

After the recent patch he has become a braindead spammer to be honest , try to play safe and ask for help if needed .

Mordekaiser

The best thing you can do is build magic resist and don't R before he uses his R , it will not follow you into Morde's shadow realm.

Nasus

You can wi. early game but dont let him free farm because it seals your late game defeat.

Olaf

Be carefull of his lifesteal and R that makes him invulnerable to your brittle , second R cast and E .

Pantheon

Not great but not terrible, try to hold lane anp remember to ping ss because he can roam and abuse his R.

Poppy

You win late game so try to scale off with the lvl 12+ powerspike

Quinn

Quinn is a terrible matchup for orn , she outranges you a **** ton and also has a **** ton of mobility.

Renekton

Try not to fight extensively with him and you can lock him down enough for your jungler to help you kill him .
