“TL;DR - EVEN LANE IN YOUR FAVOR EARLY. DUMPSTER HER PRE-6. CONQUEROR IS GREAT. STRIDEBREAKER MAKES HER A FREE KILL. DON’T LET HER FARM. SHE IS A LATEGAME NIGHTMARE.
Kayle is not 5 due to her early laning. Though her slow and her poke are somewhat annoying, you should be able to stomp her easily pre 6. Wait for the wave to be on your side of the lane and then run her down with ghost once you get a pull or once she missteps. Make sure you kill her over and over again and try to prevent her from farming as Kayle can win lategame by herself. Phase Rush is recommended for this lane as it lets you run her down even without your Ghost as her slow won’t be able to stop you. A trick to keep in mind is that she cannot cast her ultimate when she is stunned. So if you/your jungler/whoever’s working with you possess the burst to kill her quickly, you can do so by pulling her and chain ccing her. But that requires too much coordination for soloq. Just something to keep in mind if you have a duo or something. After she gets her ultimate, it shouldn’t be too difficult to run her down still. You have two options. 1) Burst her down quickly BEFORE she can ult. 2) Apply stacks on her and get her low enough so that you can kill her with your ultimate AFTER she ults. If you are looking to burst her down before she ults, it might be a good idea to do your combo on her (AA+W+Q)and then pull her in. If she hasn’t ulted, you can opt to quickly R her as this will probably leave her low enough where you can kill her with 1 more auto after her invulnerability is over.”
“You absolutely dominate this match-up early game, however, if you don’t take advantage of this and let her get to level 11 or 16, by letting her free farm and split all game, you are likely to lose. Her win condition is getting to the point where she doesn't have to rely on stacking her passive. Push her out and keep her out. You have to be super aggressive against her. You completely counter her early game due to her reliance on getting passive stacks, through auto attacking. You can sidestep her (Q) which will slow you if you are hit by it. Just keep putting her down early with (Q) even if it means getting ganked a lot.
“ The key to this lane is zoning. Assume lane dominance very early and don't push the wave at all. Freeze the lane for as long as possible and don't let her get anywhere near the wave to farm. If you can kill her, absolutely look to do so but she will usually play too safe. If you get a really strong lead and the enemy jungle isn't a threat to you, proxy her off the outer tower to deny her levels. This is the perfect time for your jungle to invade enemy lines as well.”
“Kayle will scale HARD. Start Dorans shield. Try to abuse her early game as much as possible. Q poke her as much as you can and parry her Q to avoid the slow. She is hard to catch when she has fleet footwork. If she has ult, parry that damage. Try to stop her from free farming.”
“Both tiny and extreme. Pre 6 she kisses your feet, then post 6 you kiss hers. As of 10.18, she'll be a lot more present in lane, so you might just be kissing her feet the entire game. This remains to be seen however.”
“Kayle can easily kill your tentacles, and her slow can keep us out of range. Try to prioritize death's dance. She is squishy before 6, so take advantage of a jungle gank.”
“Kayle is usually an annoying laner for immobile champions like Mordekaiser but Morde has higher ranger so you can pretty much lock down the lane completely. Pre-6 she is free food. Post-6 she is also free food. The only reason the lane is difficult is due to the urgency of you HAVING to gather a lead. If you don't stomp Kayle, she will outscale EVERYTHING super hard and take over the entire game. You HAVE to gather a lead on her early. Land every CS, punish every mistake, get every kill.”
“Free Lane: at Pre 6, make sure to Root her with your Tangled - Barbs (E) when shes about to hit a CS to cause a lot of damage on her.”
“Punish kayle very hard pre 6 because she is meele until then, seriously do not let her walk up to farm in this lane when she is meele because she basically isn't even a champion, once she gets 6 this matchup gets a lot harder because it gets extremely hard to get E's on her, but you can sometimes still bait her in to fight and get the surprise E if you make it look like you're running away and then turn on her really quickly, her ultimate also denies your ultimate but you should try to time the pull to avoid that because she can't R while she is being pulled, so if she R's early just wait a little bit before you press R again to pull her, also sometimes you can just pull her anyway and then finish her off normally if your ultimate doesn't kill her. Kayle scales pretty hard as well in the splitpush so she is scary later, but you can still teamfight well against her.”
“Kayle does not have the damage to beat you in trades until level 11, but her ranged autos at level 6 will allow her to farm more safely. Try to play aggressively to gain a lead before she becomes too strong”
