Darius

Darius will all in at level 2 or 3 and will harass you very early if you're within in his range, my advice is just play safe let wave push to you and wait for ganks to lower his health so he can't harass you while you farm. He will also freeze lane so you can't farm so play safe and be patient.

Renekton

Just like Darius he will all in at level 3 and burst you down to a very low health either forcing your flash or out of lane and not mention will freeze lane so you can't get near wave to gain XP or stacks.

Gnar

Gnar will kite you early to stop you from getting any XP and stacks which makes it really hard for you early game due to the fact he's ranged and can be hard for you to trade against. But you will scale harder late game and will be able to trade against him once he transforms as he won't have much kiting potential.

Mordekaiser

He will try to let you push in wave to put you in a very uncomfortable situation and in a position where he can bully you.

Heimerdinger

BULLSHIT CHAMPION! Just avoid him till pre 6. And build MR and go Dorans Shield.

Sion

Overall very tanky champion and will harass you early, scales infinitely with health and has hard CC which makes ganks hard to avoid.

Tahm Kench

Tahm Kench will harass you early game around level 2 due to the fact that you're very vulnerable early game making you a very easy target for first blood due to the fact he can all in very early due to his passive.

Teemo

Will kite you to force you out of lane and will also freeze so you miss out on levels and farm which make it hard force you early to mid game. Best choice is to rush MR such as Spirit Visage and Mercs.

Fiora

Scales early and late. Best way to trade against a Fiora is not trade at all until mid-game where you have power spike advantage, but around late game where she has 5-6 items she will kill you. So best to defend against a Fiora early is just build bramble vest and and a sapphire crystal just for extra mana.

Master Yi

This is self explanatory. Fed Yi = Your death, if you meet with a fed yi just wither and run because you can't 1v1 unless you're also ahead or fed.

Ornn

Wins from item advantage due to his passive and will be hard for you to trade against.

Olaf

He will go aggressive on you early game by poking with his axes so make sure to avoid his axes by weaving and get early ganks if you can so he can't ult from your wither. But don't overextend mid game as well as this match up is favored for Olaf.

Riven

Wins early as her kit scales harder early but once you hit level 6 you can bop the living daylight out of her.

Illaoi

Will harass with Q and E. So just play safe and if she does E just back away from her and stack from he tentacles which will make up for some of the minions lost.

Jax

Jax will harass you early from level 1 with his E to make your empowered Q worthless to trade against him. Just wait till mid game and you'll win with trades, but a good Jax will know not to fight you so don't bother chasing him and just be careful of ganks.

Camille

She wins short trades.

Dr. Mundo

He will out damage you early but once you get sheen and get ganks you win pretty hard.

Garen

Simply champion but still deadly early for you. Suggestion is just to let wave push to you and play it safe till mid game.

Irelia

Freeze lane don't overextend and just waist her time. If its a good Irelia she will try and get early pressure so don't get within her range.

Cho'Gath

Be cautious when he's reaches 6.

Fizz

Build MR.

Jarvan IV

Play safe early, don't let him pick on you, wait for ganks and wait till pre 6 and you'll win mid game.

Malphite

Can't win lane against you, just farm and try to force him out of lane so he'll have to make plays in different lanes which will make you be ahead by a lot.

Amumu

Alistar

Ashe

Aphelios

Azir

Blitzcrank

Brand

Braum

Caitlyn

Draven

Akali

Will play aggressive but will get minion aggro.

Cassiopeia

Ahri

Annie

Anivia

Aurelion Sol

Bard

Kayle

Skill based.

Gangplank

Can W your wither and can trade harder early and has a slow, heal, burn, and range poke.

Quinn

If you think you can't gain stacks or farm and have a hard time then put your points to E and start corrupting pot to help you sustain longer so you can rush bramble, tabi, glacial shroud, just something to counter her early to mid game.

Pantheon

Will harass early so play safe and let wave push to you. Mid game Nasus wins.

Poppy

Get 6.

Galio

Can't really stop you from farming cause he will end up burning mana, so overall you're fine in this matchup.

Kennen

Buy MR and whatever damage he deals to you, you can Q 1 or 2 minions to gain the same amount of health you lost from his poke. Also watch out for his dashes use and junglers, max wither and he's good as dead.

Jayce

Kassadin

Buy MR and no point in chasing unless he has no mana.

Rengar

Let wave push stay away from the bush's and wait for ganks, Nasus wins mid game.

Ryze

During mid game let him push freeze lane under tower and go ham on him, buy some MR and max wither.

Maokai

Nocturne

Don't go to deep early as he will kill you just let wave push to you and freeze it but getting last hits and wait for Q. You scale harder mid game.

Shen

A good Shen will play very aggressive whenever he gets a chance to pick on you and his W on your empowered Q is useless, best option is just to back away from him and wait for ganks. Also watch out for his taunts when he's diving with the enemy jungler. This is a pretty hard match up but not impossible if you know what you're doing.

Corki

Ekko

Skill based.

Elise

Evelynn

Just back away towards your tower if you have nothing up, other than that you destroy her.

Kai'Sa

Ezreal

Fiddlesticks

Jinx

Jhin

He can't do anything on his own.

Kled

Will play aggressive on you and let wave push to you.

Karthus

Gragas

Graves

Kha'Zix

Watch for early ganks get vision.

Yorick

Hard to trade against E his minions when they're aggro on you and just play safe against this champion.

Volibear

Play passive and wait till 6. He can't all in if he's too deep in your side so let wave push and freeze lane.

Wukong

You scale harder mid game.

Yasuo

Just buy bramble and you've won lane but do watch out for their jungler as that is what will make the lane hard for Nasus.

Singed

Don't chase wither him if he's chasing and just farm and get MR and watch out for jungler.

Udyr

Get some vision early because he will gank you if you go too deep in lane. But once you get you get some items around mid game you can fend him off.

Tryndamere

It's Tryndamere this is very self explanatory. Stay just far enough to gain XP and where he can't pick you and let wave push and freeze and wait for ganks. Just watch out he's slowly walking up to you.

Urgot

Play safe, freeze lane, and get ganks he's very squishy early and will try to poke you but putting pressure early on you. But you scale harder mid game.

Trundle

Will trade with you early as much as he can to throw you off so play safe and wait for ganks, watch out for teamfights as he has more of a advantage as he has his ult. Can also win mid game so take extra care against trundle.

Diana

Freeze lane and farm easy match-up for you. But you're susceptible for ganks if push to deep.

LeBlanc

Hecarim

Kindred

Use her ult to your advantage.

Kai'Sa

Kalista

Morgana

Can't wither with her spell shield up, and watch for that root.

Karma

Ivern

i mean, it's Ivern.

Janna

Fast...just very fast.

Lee Sin

Has fast ganks and hard to avoid if the top laner and lee sin are both on you so make sure have flash or vision early.

Sett

Sett's W won't be much of a problem since you won't be trading with him early on. Best thing to do against this match up is to just last hit with Q if he's freezing lane and if pushing tank the minions close enough to the towers so you can freeze with your wave. I recommend going ice born gauntlet over tri-force.
