“Amumu can be a little annoying for Lillia because of his ability to lock you down with his Ult and Q. However, you do have better ganks and farm. Keep your Q stacks up and he should never be able to land a Q unless he ults you first. Definitely build merc treads earlier than later in this match up.”
“You can dodge his Q and Ult, you can still use your W in his Ult.”
“Not as much countered as you think. Early AP amumu isn't a joke nowadays, lategame he is a beast, and with the new jungle and Purple Smite he can farm freely even if you steal his blue.
What can you do here? Kill him on his jungle over and over. clear his big monsters so he cant farm, take EVERY SINGLE DRAKE of the match and try to win as soon as possible.”
“You beat Amumu early game on equal footing. Do not fight him however if he has an HP advantage.
Mid game it can become quite hard to punch through his Aftershock keystone as base Kayn. If he has another keystone you are able to out-duel him. Try your best to dodge his Bandage Toss (Q) with your Reaping Slash (Q). Avoiding stuns is crucial to winning a fight. Consider building Mercury's Treads.
As for late game, Amumu becomes jungle food if you have chosen to go Rhaast. Your Black Cleaver will melt him.”
“Haven´t played this match up (will be updated whenever I have played against Amumu as Graves)”
“Dog champ, just counterjungle him, what's he gonna do? cry to his mom?”
“Helpless mummy can't do much about you, he does not have the damage and outside his ultimate he doesn't have enough reliable crowd control. If he's in a bad position you can easily kill him as he has no reliable escapes either.”
“Useless champ against you, just take conq and you will out damage him, super easy match up for you”
“He just sucks to play against. Lots of cc for both blue and red Kayn. Also really good at stacking armor which naturally, blue Kayn hates. Red Kayn he's not so bad, just peel for the people he Q>R's. He's really broken right now, might be a good ban choice on Kayn
Honestly on both forms don't 1v1 him. heal cuts if he has conq. on Blue kayn.”
“Easy, little kill pressure vs EVE, slow clears, unhealthy clears, bad scaling”
