i probably wouldn't think of kennen as a counter to elise
oh but i guess you are talking about ppl who do ok against her woops
Yeah, he's more of an annoyance rather than a straight-up counter. She has to walk in his range if she wants to poke and he has more follow-up within that zone. One good gank from her jungler and she can simply apply brute force on Kennen, though.
Yorick potentially forces her to adapt her build to something far from optimal and maxing W over Q to make the most out of that lane. I say potentially, because Tear vastly negates any advantage he could create by himself. Other melee champions winning against Elise largely depends on her screwing up one way or the other; be it through bad general positioning, overextending when your jungler is approaching or misjudging the trades in damage / missing her stun in the even-ish match-ups.
The 'lolno' group (varying in severity): Aatrox, Akali, Cho, Darius, Fiora, Gangplank, Garen, Jarvan, Jax, Jayce, Lee Sin, Malphite, Olaf, Pantheon, Poppy, Rengar, Rumble, Shen, Shyvanna, Singed, Tryndamere, Udyr, Vladimir, Volibear, Warwick, Wukong, Xin Zhao, Zac.
The 'maybe' group: Irelia, Renekton, Riven. The end.
Susan and Trundle were left out because they act as a late game gamble. Their initial lane presence against her will be pitiful, but they can bank it all on reaching their item goal. After Spirit Visage + item of choice (BoRK for Trundle) their sustain will be too overwhelming for Elise to push back, so after the mid game period those two are able to heavily pressure top lane whilst having superior scaling for teamfights at that point in time. That is if for some reason she did not get involved elsewhere after a big lead, or was unsuccesful in doing so.
I think that about covers it without going into the nitty-gritty. Sleep time now.
