Darius

Just permaban this champion. Darius already screws over most melees in the game, but in the case of Rengar he can just obliterate you so easily that the moment he gets ahead you are pretty much done. You need to put in at least 10 times the effort he needs to beat you in order to go even in lane, and, taking into account he is very popular nowadays... banning him is just the better option.

Garen

Similar to Darius but somewhat more manageable. Early levels you can deal with him fairly well, try to whittle him down constantly so he can't heal with passive before going in for the kill. Try to save up your stacks for his Q silence so you can double W and come away fairly unscathed. If you get a significant enough advantage it will turn into a farm lane, a fact which you can use to pressure anywhere else. If he gets to 6 without you having secured a lead however the match will go downhill for you. I would recommend either a bruiser build (sustain works wonders) or stasis. If he gets ignite however this matchup becomes significantly harder, but if you get help from your jungler you can push top somewhat soonish and help elsewhere. TP+Flash recommended, either conqueror or grasp work fine.

Yorick

His W wall is bugged up the *** and the moment he gets his core build he will wreck your **** because of his ult. He is very rarely picked however, and you can screw him up considerably early game. Pushing against him is hard however, and his late game pressure is hard to match. Bruiser builds work wonders here, specially sustain and aggresive, but do note that the moment he gets his full build 1v1 him is an ill-advised proposition. Ignite+Flash is good if you want to pressure him early, else Flash+TP. Conqueror or grasp can both work, but he is favored in prolonged trades, so keep a note on that.

Gangplank

You wreck his **** so hard it's somewhat sad. Barrels just give you gold and a place to jump to if you time it right, he is squishy as hell and the only annoying thing about him is the fact his W is just a lifesaver. In the worst case scenario, lane will turn into a farm lane, but even then you can still pressure him somewhat. He scales pretty hard however and his ult gives him global pressure, so the sooner you end the game, the better; else you will just be eating powder the whole game. Flash+ignite is a good pick if you want to wreck his **** ASAP. Most rune pages work well here, but you might want either conqueror or HoB.

Aatrox

Early to mid game oriented champion who can act as a drain tank. Depending on how you both play this lane, either you leave him into the dirt unable to do anything but farm, or he becomes a sustain nightmare that you need 3 people to take down. He is fairly weak until level 7-8, which is where his Q's base damage starts skyrocketing, so you want to put pressure on him ASAP. He can deal fairly well with your all in if he times his abilities right and if he gets ahead the game goes downhill real fast, so you might want to take flash + ignite to secure the early advantage. Conqueror works fine but aatrox likes extended trades to a degree, so you might want to consider grasp or HoB.

Mordekaiser

Snowball lane. If you get an early lead he will be unable to do jack**** about it, but if he manages to get seekers + liandries soon-ish, he will hurt, A LOT. He is also AP, so defensive options are limited. Do note Morde LOVES extended trades, so try your best to avoid his passive proc, else you will lose every trade because outhealing his DoT with W is impossible. Do remember your emp W cleanses his ult, but if he is smart he will wait until you have used your stacks to send you to his death realm. Also asking for ganks after 6 is wasting your jungler's time, since he will just ult one of you and either manage to survive or even kill one of you. Overall manageable, if volatile lane. Either ignite+flash or TP+flash works well enough. Conqueror is preferable.

Riven

Frustrating matchup for the most part, you can pressure her heavily from the very early game but from level 3 onwards she will just dash away from everything you throw at her. Early is in your favor, however if she gets to level 6 without any problems she can start wrecking your ****, and she gets more annoying the longer the game goes on. If you do manage to snowball however she will be left behind into the dirt and have a hard time coming back into the game, which you have to abuse in order to end it early.

Cho'Gath

He telegraphs himself a lot and his early levels are not that strong. He gains a significant spike once he gets 6, but if you manage to dodge his Qs and bait his W silence with your empowered W you will make mincemeat of him. If you ever get a sizeable lead on him just push as much as you can so you can take down turret fast and roam, since he will do jack**** for the rest of the match. Do note he can set up fairly good ganks, so watch out. If he gets ahead he just becomes a very annoying meatwall if he went tank, but he can give you trouble, so watch out. Either Ignite or TP works fine, and you can take most runes into this matchup.

Akali

Very annoying champ who can poke you down with ridiculous ease and confuse the hell out of you with her shroud. However, she is very snowball reliant and if she falls behind she won't come back. Early levels are in your favor until she starts getting more and more points in Q, then at 6 you need to be careful or she will snowball out of control. If you are able to kill her at least twice you will be fine for the rest of the match, she can't do anything to you unless you **** it up majorly. Either Ignite or TP works here, and you can pick any runes you want, but if you REALLY want to secure an early lead then Grasp is ideal.

Fiora

The bane of most of the top lane melee picks, Fiora is just disgusting to face overall, and if she manages to get ahead of you at any point the game is done; however, since you can bait her abilities fairly well, you can actually kill her from levels 2-5, and if you secure a lead she will just be a particularly annoying cannon minion. Do note Fiora's level one is stronger than yours because of how her Q and vitals work; avoid facing her directly until you are at least level 2, then start going ham to try and make her fall behind. If she gets to 6 without you achieving a lead it becomes an uphill battle since she can hard outscale, but you can try and get a Bramble Vest + Tabis early to delay her from killing you, though it's not optimal. Ignite is preferable if you think you can kill her before 6, and Grasp works wonders against her (conqueror won't do much to help you duel her). A bruiser build (or an aggressive stasis one) are ideal.

Camille

(Placed in Even because of her scaling; if you win lane early, it's Minor). Surprisingly it's a matchup you can actually deal with rather well, since your early game dueling is FAR stronger than hers; just be careful around her shield, you need to always check when it's up so you can poke her, proc it, and then fight her once it's down. Even after 6 you can still somewhat reliably fight her, though it becomes much harder if she manages to snowball. Do note her E is a very safe escape spell because of how top lane works, so she can be slippery, but she sacrifices any potential engages she has early game to do so. Just be careful around her W poke and respect her gank setup potential (E is a very strong stun) and this lane should be a relatively straight forward one.

Ignite and TP both work just fine. As for runes, you can either go grasp to secure early dominance, or just conqueror if you want to ensure you will keep on winning. Any build works as long as you are ahead.

Irelia

It's actually surprising just how well Rengar can deal with Irelia. If you manage to dodge her E and fight her when she has less than 3-4 stacks of her passive, she can't do **** about it, since you actually outdamage her significantly early game. Good wave management will also screw her over since she will have a harder time stacking her passive, and the only really annoying thing about her is her W defensive steroid. If you manage to kill her twice then it's almost gg, since she can't risk farming without you beating the **** out of her. However, do note she can set up ganks quite well and if she gets too ahead she will make mincemeat of you, but you still have a lead.

Trundle

Trundle is basically an early to mid game mix of both Jax and Nasus. He does what they do, but earlier and much faster, at least at first, while also being a pretty good melee bully. He also loves to fight people with limited mobility that he can retain in his W AoE. Your mobility is limited and you are a melee assassin / bruiser without natural on demand escapes. Do the math.

Be very careful around Trundle at every stage of the game since if he plays it correctly he can completely **** you over and make you absolutely irrelevant very very fast. He is also a pushing monster, and was benefited from the changes to BotRK significantly, which gives him the option to get it and thus ensure your next 20 minutes of existance will only know pain. To be honest the only way you have to deal with Trundle as a top laner is to hit and run him and then flee the moment you've used up your combo before he pillars you into his loving arms. From 6 onwards fighting him with his ultimate up is suicide, you will need to bait it out of him first, flee, then try to go in again if he didn't beat you half to death with his club. The only saving grace of this matchup is that you can kite him decently and if he ****s up he will be put behind considerably. He also pushes pretty hard once he gets tiamat, which can be abused into getting him ganked.

I would recommend tp over ignite unless you are 100% sure your jungle will camp you early, since it's hard to kill him on your own. Either conqueror or grasp works fine, but DON'T go with a heavy defense build (like tank stasis or similar) because you will be giving him free stats in teamfights. Never focus him unless he is near death's door, he will never die from your burst unless you are superahead.

Renekton

Nasus

Always respect the cane. His early game is garbage, sure, but if he ever manages to scale you will do jack**** against him since you are a melee champion who is all or nothing, and he LOVES facing against those in the mid to late game. You will have a relatively easy time until he gets Sheen and 100 stacks, then with his ult he will start winning most fights. Keep the pressure going from very early, the longer you delay his powerspikes, the better, since it will allow you to snowball other lanes and win the game before he becomes a problem. Don't leave him too much on his own however; he can splitpush VERY hard with some stacks and you might find yourself short an inhibitor.

Ignite works well since you want to kick him out of lane ASAP. Conqueror is also nice, albeit you might want to consider changing bloodline for tenacity to deal with his slow. Bruiser builds work well against him, and you might want to consider getting BotRK.

Yasuo

It honestly depends on the ability of the yasuo in question. Bad Yasuos are a weeb minion, good Yasuos have to be respected, and great Yasuos can beat the **** out of you before you even notice what the hell was going on. To beat Yasuo early, focus on poking him down little by little, abusing the time his shield is down the best you can, then going all in once he is at 50% HP or so. His early game is fairly bad and he is one of the most item dependent champs in the entire game, so if you actually set him behind he can't do much - but if he gets a lead, the very same thing goes for you too. If he is smart he will rush phantom dancer, which means you will have to work around at least two shields, but if you are ahead it won't be much of a problem. Always be careful around his W, he can block your emp E and screw you over since your ferocity is down. Once he gets iE+ Zeal item + sustain his damage and dueling becomes insane, and you should only fight him then when you have around 2 to 3 completed items yourself.

Exhaust works well if you feel you will need to slow him down in fights, else ignite also does the trick. Conqueror or HoB are good for the job.

Sylas

Fairly easy match up after the heavy nerfs Sylas received throughout his lifetime. The only things you need to be wary of are his W heal and the fact his E ratio is huge, but his early damage is VERY poor and any sort of healing reduction item cripples him, which in turn opens him up for the kill. Do note he scales HARD as the game goes on and if he gets a lead you can be in for a world of pain, so make sure things don't get to that point. If you ever get ahead however congrats, it's become a 5v4.

Ignite is good if you want to pressure him early, but you don't strictly need it, so TP is an option. Conqueror and HoB work best.

Vladimir

Teamfight monster who actually has a relatively decent early game against most melees. He takes a while to get going, but the moment he gets his core or a lead, he will just bring bloodshed wherever he goes. Luckily, Rengar can deal with him fairly easily, even from early on. Just poke him when you get the chance, avoid his empowered Q so he doesn't get an increased heal, and keep a constant aggression up to make him lose farm. If you manage to kill him once or twice just focus on pushing top lane ASAP and roam, since you won't really get much from killing him and it's fairly time consuming if he has everything up. Be careful once he is 6 however, if you don't respect his heal and increased damage you might yourself short a couple liters of blood. An early executioners does wonders against him, and cripples him greatly for all-ins and ganks.

Ignite is recommended. For runes pretty much anything goes, but either conqueror or HoB can help significantly in making short work of him.

Quinn

Unbelievably annoying lane bully who can actually scale fairly well into the late game, while also having such a good roaming ult that she can afford going ignite without sacrificing global pressure. She is a ***** to deal with in lane, mostly because she can poke you for free and the moment she gets a proc or two of her passive on you that's 50% of your HP away. It's not completely hopeless, however: since she is an ADC, if she messes up with any part of her combo, she is dead, because she can't withstand your burst. She doesn't make it easy at all however, and the fact that she can see you in bushes every now and then with her W is frustrating as hell. I actually recommend going lethality here if you don't need a tank, since you can burst her down hard and ensure some semblance of pressure.

Either Exhaust or TP work fine. You can take ignite if you are 100% sure you will win early. Grasp or HoB are recommended here, you want either short trades or all-ins.
