Camille Minor I feel she's a stronger laner, not sure about he clear speed. Seem's cooldown relient tho so dodge abilities and slow with Q like with most matchups. Focus on counterjungling and counter ganking. She has some surprising burst and good counterganks so be careful.

Graves Minor Unless he get's handfed bib and all he won't be any problem especially after 6. As long as you dodge his Q and hit him with yours he will start to run and at the point you've already won as another Q + E and Tiamat will be more than enough to instantly turn the tide on him. If he does hit u, Q him and kite away. He's still somewhat squishy early game too so don't be afraid to punish an early mistake. Out scale him and keep taking his Raptors. (7.7 Nerf) His true grit doesn't grant him MR anymore so your Q / W do much more to him therefore I moved him down in difficulty this patch. (8.1 Slight Buff) Be more careful of his smokescreen, try to deek / have ghost or flash ready.

Hecarim Tiny Your Q slow's him for 40% for 2 seconds allowing you to successfully lower his damage as well as catch up to him with ghost and [[Sadism]]. Try to keep him slowed as he will usually ignore you and dive your squishies. Peel peel peel. Counter Jungle him often as he is somewhat slow and can be low sometimes around red or Krugs.

Kha'Zix Minor Same deal as Graves. Unless he gets spoon fed he really can't handle your shenanigans at 6. He's generally really squishy and very low in the jungle as his W is his only heal other than lifesteal. Take advantage of his early clears and steal a buff potentially while he's doing it. If he does get a little fed, nothing some armor and a Sterak's Gage won't solve. Try to peel for your team when he's MIA.

Master Yi Major Most high attack speed champions will take advantage of BOTRK and Bloodrazor Enchantment. To counter this build a Randuins, Thornmail, Sterak's or GA as armor is better than HP vs those items. Generally speaking get Skirmishers earlier if he's 1v1ing all the time. You can pick up a Phantom Dancer for a total of 32% Damage reduction. You can keep up with him when he ult's if you're close distance with ghost and Sadism however you can only slow him when his Ult his down. Again peel for your team and warn then when he's MIA. He loves performing a clean up on your team with his kill-resets. If your team has a snare get them to save it for Yi and burst him down easy. Other than that focus on power farming, ganking, and stealing Raptors. I wouldn't go too far counterjungling him unless I'm ahead.

Lee Sin Even Position Position Position. Make sure to dodge Q's and land yours when his is on cooldown. Be very map aware and be sure to get a deep Ward on him so you can track his pathing better. The last thing you want is him to ward jump, flash and ult you into their team. #1 Lee sin has trouble clearing Raptors so take advantage of that and Clear yours and his every 1:40. This is my focus every single time I play a Lee sin. That and killing him or zoning him well before a Dragon or Baron. He's got one of the easiest steals in the game due to high mobility. Keep warding outter crust of either pit and you're gravy. Be alert and ready to fight Lee in your own Jungle as most of the time you can pull off a kill if your ready. Otherwise ping a Lane to help.

Olaf Major Olaf generally counters your kit as he has high lifesteal, true damage burst, a slow similar to yours and an Ult with CC-immunity. Like with Master Yi you can't Q him when he ult's. However I only feel he's 8 out of 10 because he's basically kite-able all game when his Ult is on cooldown and pretty predictable when he does. You can simple ghost or Ult or both in worst case scenarios dodging his Q's when you can. This matchup is very skill based 60-40 him IMHO. You can out farm, out gank, but not trade him 1v1 unless you're ahead or get a good HP lead / PD or Skirmishers. I've never really had an issue with Olaf because his early is almost as terrible as Mundo's. Focus on Raptors both sides and counter ganking him when possible. Try not to 1v1 him unless you know you will win it. Build a Warmog or Sterak's for the True damage as you need a bigger health pool. Beware of BOTRK if you do though.

Volibear Even Exact same deal as Olaf but more tank less spank. Don't engage 1v1's counter his Jungle and anticipate his pathing as he can counterjungle you / gank you, especially before level 6. His passive is 30% HP over 6 seconds (120 CD). Your Sadism is 60% over 12 seconds (70 CD)(max rank). He's basically a mini Mundo. You can get a Banshee's vs him so he's forced to waste either his Fling, Frenzy or Fear. Generally the burst on your team and a Titanic Hydra + Sterak's Gage works well for burstin' yogi bear.

Vayne Extreme Get a Dead Man's Plate, Titanic Hydra, Randuin's Omen, Scanner and possibly Sterak's if one Titanic burst isn't enough to kill her. Generally speaking you need to get your team on board with saving their cc and burst for Vayne. Be sure to ask someone with mana to grab Frozen Heart as it lowers her attack speed an additional 15% (stacks with 15% on Randuin's) . You may want to take care of vulnerable targets first if she's playing safe but as soon as she starts engaging, scan when she ults, hit her with the Deadman's AA + E with Titanic Active and Use Randuin's / Q when she tumbles. You may need to hit Q / Randuin's first before the Deadman's. You will learn how to deal with vayne's the more you play Mundo.

Kog'Maw Major Same idea as Vayne but without the annoying tumble and invisibility. Just dodge his skillshots especially his Q. He's a lot easier to lock down than Vayne but has a longer range with W on and can shred Tanks (You) like nothing. Get the same items mentioned for Vayne.

Nocturne Major I really love watching terrible people play my Main against me. If I were queue'd up as Nocturne vs a Dr.Mundo my immediate reaction would be to deep ward, look to steal a buff (usually blue as an intelligent Mundo would start raptors or red). What Nocturne generally will want to do against you is W your Q then Q + E you and if he has Ult he will save it for when you Ult. So to deal with this. Don't throw obvious Q's at him, and make sure he's at max distance when you do throw them at him. If you ever see him W and you didn't throw a Q, wait for it to go away, Q and punish him as it's a 20 / 18 / 16 / 14 / 12 Cooldown. Having Mercury's Treads + Elixer of Iron + Burning Agony Active will make his fear basically useless against you. Randuin's will lower his attack speed and crit if he was dumb enough to get some. Most noct's build lethality / botrk / bloodrazor / maw and have 1-2 tank item's possibly. The basic AD counter build works against him. Another thing to note is when he hit's level 6 and starts ulting into lane's destroying your allies, you have to take advantage of his position. If he is diving you can countergank and kill him. If he's good he'll get in kill get out no problem. Therefore for example if he ganks bot lane, gank top or steal his top buff and raptors. Keep to the opposite side of the map of him and keep farming scaling and stealing his buffs. It's basically a gank war with Noct so you gotta make quick decisions. Sterak's Gage also help's quite a bit against Noct's burst.

Vi Minor A lesser evil lee sin basically. Avoid long fight's with her to avoid her stacking denting blows. Instead keep her Q kite'd until she gets frustrated and tries to kill you eventually. She wont be able to lock you down as you have Burning Agony and Sadism available. I usually have no problem trading with her, it's usually more a problem holding her down as she like's to Q into and ally and 1 shot them with 0 items. She's pretty broken as far as kit goes but she's ok right now with the recent nerfs. I usually ban her or lee sin as she is also good at stealing dragons and baron alike. I'd suggest an early invade with your team to take a buff or deep ward and gank / steal it. Make sure tell allies to keep their distance from her when in teamfights as she can Q and R and close distances fast. If you're nearby you can usually slow her and have your team cc / kite her to death. Focus on peeling mid-late vs her.

Shyvana Tiny After he W nerf (20% bonus damage to monsters) she only deals 20 magic damage per second compared to Dr.Mundo's W dealing 35 (at level 1). At level 5 Shyv's W = 70 and Dr.Mundo's W = 95. This is only counting the AOE damage not Shyvana's on hit magic damage on W which eventually does more by her 3rd hit to her main target only. Her e allows her auto attacks to deal 2.5% of your max hp so avoid building a Warmog and build a Randuins / Dead Man's Plate instead. She tend's to get tanky so your Q's will start doing a lot to her. Your clearspeed is faster than her this patch due to the nerf and if you get tiamat and she doesn't you will be ahead. Deep ward and take a buff or raptors if she's not around. Counter jungling often isn't too effective against shyv as she clears just as fast as you and will take the opposite side camp's. Now what I like doing is stealing Blue, Ward my Blue and clear my Red. If i see her go for blue my Mid / Top will destroy her immediately let alone me gently strolling by and smiting it or Q'ing her from fog of war. Build some MR against her first then some Armor. She's around 60% AP 40% AD.

Xayah Minor Don't throw an obvious Q at her save it for after she ult's and keep juking her horizontally. Keep note of where her feathers are, do not stand between them as giving her a free snare can be very punishing / deadly. As soon as you're in her face like and ADC you will be too much to handle. Care her lategame.

Rakan Tiny Even if he pop's you up or ult's you, with level 1 W u have 30% tenacity with the Swiftness mastery. Mercs and Elixer of Iron can help with his CC or anyone's in general. With level 2-3 Sadism (Ult) you'll be able to keep up with him and ghost if you need it. He's very squishy just a Q or 2 and he'll dash. Not that bad a guy. Try to save your Qs for after he dashes, and note he's has 2.

Udyr Minor As long as he's not spoonfed you're extremely safe in this matchup. He can't really catch up to u if you keep him slowed with cleaver. Kite him. If he flash bear's turn on w, ghost, ult and run he won't be able to stick to you unless he has allies CC'ing for him as well. Build merc tread's if that's the case and buy elixer's of iron regularly for the Tenacity. If he's ahead you can take a zeal instead of tiamat and go phantom as it will allow you to skirmish him if he's taking you to lower hp's. Also sterak's helps a lot with this build as it allows you to be a lower health's longer and safer while giving u some massive base damage synergizing with your E. Crit's with E are no joke and can do roughly 600-700 mid-lategame.

Jarvan IV Minor His clear's aren't ideal and he's pretty easy to counter-jungle in most situations. He's a burst AD so Sterak's, Tabi, Randuin's help greatly. Your Q's do a lot to him if he's building tanky / a lot of hp. Generally speaking you melt him down, just avoid his flag jump as he'll ult you. Take Flash vs him if he has a team with good initiation / cc as you will need it to get out of his ult. He's somewhat kite-able so abuse your Q range.
