“Mundo is never a problem because his early game is just terrible in my opinion, consider buying an executioners calling in this matchup to make his healing even worse, you can usually kill this guy many times before he hits level 11 and that's when he becomes a decent tank where his ultimate actually heals something, look for all ins at level 6 once you have your ultimate as you should win them everytime since his abilities basically hurt him and you have consistent damage and his level one ultimate hardly heals anything especially if you have an executioners calling. Also block him from farming cannon minions by tanking his cleavers.”
“Really the only thing needed to be taken into consideration while fighting a Mundo, is straight up his cleavers and his massive sustain. He will spend quite a large amount of time keeping his distance and landing his cleavers to last hit. He will become a threat the moment he keeps landing cleavers on you since he can proceed to run you down. A more mobile and poke approach is more favorable. Each time he kills a minion with his (Q) it grants him half of the life cost spent. You can body block cannon minions to prevent him some gold. Watch his body language to avoid getting caught out with his allies gank.
“Avoid his cleavers as they slow you quite a bit aswell as deal hefty amount of damage. You have low kill pressure on him once he get's a few items. Blade of the ruined king is pretty good against him. Again, Excecutioner's Calling is a great choice against a healing champion like Mundo.”
“Very easy early, just poke with Grasp and kill with Ignite.”
“TL;DR - EASY LANE. DON’T GET HIT BY FREE CLEAVERS. FREEZE LANE AND RUN HIM DOWN. CONQUEROR RECOMMENDED. EXECUTIONER’S CALLING IF HEALING BECOMES A PROBLEM.
Mundo can be somewhat annoying to deal with but he is an immobile tank. He actually has no way to outtrade you unless you get hit by every single one of his cleavers. And that is essentially the only trick you need to know in order to beat Mundo. Either dodge his cleavers or stand behind your minions. All he can do is throw his cleavers and farm from a distance. But doing this will actually lead to you being able to freeze better as he will be actively damaging the wave. Since he essentially has no escape from you, you can simply run him down if he walks up too far and tries to aa the wave. Ghost is more than enough movement speed but if you struggle to chase him through his cleaver slows, you can take Phase Rush. Conqueror is nevertheless, preferred though, as you need to punch through his health. Mundo will be stacking up his health quite a bit, which is why you need the extra damage. Another thing to remember is that his ultimate costs a decent chunk of health, which might leave him low enough for you to oneshot with your fully stacked ultimate for a splitsecond. If a Mundo gets fed, your team will hate you a lot, as a fed Mundo is actually impossible to kill. If his ultimate healing becomes a problem for you, which it shouldn’t, then a quick executioners calling will do the trick. ”
“Mundo is a bit of a meme but it's tricky to really do anything against him. His R outruns your R, his Q chunks you if you're going tanky. Best to shove lane and try your best to peel him off your team in teamfights.”
“Dodge his Qs, get early Executioners. Punish his pathetic early game as he has 0 ways of dodging your combos. His midgame spike is insane though unless you managed to get ahead far enough.”
“This match up is pretty easy just because in most scenarios Mundo just lacks kill pressure to punish you in lane. He also does not have any dashes or escape tools other than his ultimate (which you can just build Mortal Reminder against or ignite him) so it is very easy to dive him as well.”
“Theres no much you can do against mundo.
His Q scales from your Hp and his W reduces the duration from your W and gives him more MR.
But from mid-late game and if you have grievous wounds he should be easy to kill whit R.”
“Dr Munso will become unkillable and can also constantly run at you by throwing Qs. His Q does % health magic damage which counters both your health stacking and Thresh soul passive (because Thresh does not gain mr). I would build chemtank in this lane and rush a bramble vest (or executioner's calling) to deal with his ultimate. You could even consider taking tenacity runes because it's hard to get away from him.”
