Ashe

Genuinely the best matchup Olaf can have on bot. With good support she may beat you early, but after 6 you straight up run her down at any point of the game.

Caitlyn

Rough early, as you won't get to farm a lot but only the exp matters early so as long as you get it you are good. Even if you feed her a bit early you can run her down after 6, but watch out for her e. She will outscale you in teamfights but you can always kill her 1v1/1v2 if she isn't very ahead.

Aphelios

I haven't played against him as an adc, but he is weak early and doesn't have any dashes so you can abuse him. He will however outscale you in teamfights so you need to get a lead

Corki

Draven

Just don't get him fed early and you can run him down after 6.

Ezreal

Annoying. Watch out for his dash and poke.

Jhin

He can be annoying late because of his move speed and because he builds swifties. You may want to consider hexplate first against him.

Jinx

Outscales you very hard.

Kai'Sa

If she has good spacing she will be a pain in the ***.

Lucian

He has a dash. If you can get on him you can easily kill him.

Miss Fortune

All she has is a lot of move speed. If she has good spacing consider hexplate first.

Nilah

*Gwen is Immune* but for attack champions.
Early is good but late she will outscale you hard, plus if you don't manage e properly she will make your ult not refresh.

Samira

Except of her dash she isn't really a problem if you don't feed her early.

Senna

Annoying but you run her down after 6.

Sivir

All she can do is block your first q with her spell shield. You generally run her down.

Smolder

Until he scales you get to run him down non stop. His e is annoying but unless he has a wall to escape you can run him down.

Tristana

If you can get to her when she dashes away you kill her

Twitch

If he appears you can run him down. He has no escape other than his invis.

Varus

You can run him down.

Vayne

Unless the vayne is very bad or your support has a lot of cc you just lose because of her invis and true damage.

Xayah

She goes untargetable - bad for you.

Kalista

A semi-competent kalista won't let you touch her without ghost. You need to perfectly predict your axes to kill her.

Yunara

If she has good spacing you will have a bad time. You want to consider hexplate first.

Zeri

A good zeri won't let you touch her but you can still abuse her early if she wastes e.
