Jarvan IV

Try to avoid fighting him early game if you have scaling health yellows. Otherwise, try to annoy him/steal some of his farm when trying to camp a lane. He DOES out-tank you, but you counter his ult.

Jax

Avoid fighting him at all costs. Generally he has a better brawl than you with this build. You DO out-tank him, so late game try to get him out of teamfights, he reks face.

Nocturne

Odd champion. He's ok and pretty mana reliant. So try to invade his blue early to put him behind. You out-tank him, and he's really shit lategame, just keep him away from your squishies.

Olaf

He's got a better brawl than you and is just generally annoying. His ult cancels yours, he has better chase than you. AVOID.

Master Yi

It's Yi. You Out-tank him.

Pantheon

Generally he's pretty easy. You can cancel his engage and ulti, he doesn't build as tanky as you, and he sorta sucks late game if he's not fed. Don't engage, but prevent him from getting fed. You out-tank him.

Rek'Sai

It's Rek'Sai. Don't pick Lee into rek'sai.

Rammus

He's got a shitty early game; however, he heavily out-tanks you, so avoid him in teamfights. Try to harass his jungle if you can early, but he can out duel you early.

Rengar

He's got sustain, but you can outduel him early, just make sure you avoid bushes. Otherwise, if you protect squishies and make sure he doesn't get fed, it's alright. You out-tank him.

Shaco

He sucks lategame, he can't do anything against you when it comes to dueling. He can invade you, though. So be sure to pink one of your buffs. You out-tank him.

Kha'Zix

Kha'zix is somewhat weak-ish now. Your Q counters his stealth and E if you and it, he's highly imobile, yet has shitty disengage. Be sure to stay near squishies, he shouldn't be a problem really.

Tryndamere

Tryndamere out duels you at all points in the game. Try to deny him farm by invading/harassing. Make sure to keep Dragon and your buffs warded. He's most likely going to hard-farm for the late game. Be SURE to buy thornmail when against tryndamere. You out-tank him.

Udyr

Udyr basically sucks if you deny him farm and harass early. You nullify him lategame, just make sure he doesn't split. Useless champion. You out-tank him.

Vi

Vi's pretty easy. You can deny her engages, force her to disengage, she's pretty weak. You out-tank her.

Riven

Riven hard-counters Lee Sin all game. She out-duels him and has a heavier finish. You CAN invade her and kill her in her jungle, though. Pre-6 she sucks. She can't solo dragon. You out-tank her.

Elise

Fiddlesticks

Olaf

Nunu & Willump

Olaf

HE'S NOT YOUR BRO.

Lee Sin

GG, EASY. FILTHY CASUAL.

Lee Sin

NO CHAMPION CAN BEAT LEE SIN.
