Swain

Caitlyn

Ezreal outranges Caitlyn and can minimize her early game and outscale her mid/late.

Blitzcrank

Incredibly easy matchup. Keep E for hook and poke him down when he last hits or mispositions.

Tristana

A good tristana will push you under turret and poke you down while you lose cs since Ezreal can't match the push. Bad Tristana is extremely easy to beat since she won't know how to beat you. Keep E for Trist W and poke her down as much as you can.

Jhin

Can win almost any all in against you. Can oneshot you at any point in the game and is very hard to escape.

Kai'Sa

Stronger than you in almost all situations. Has so much burst that she can assassinate you without any counterplay. Avoid giving her isolated Q damage by standing in minion wave.

Thresh

You can dodge his hook with E and poke him down freely in lane. Still has plenty of utility with Lantern, E and R so still stays relevant even though Ezreal beats him straight up.

Aphelios

Beware of the blue gun range and red gun burst but otherwise basically a free lane phase and similar scaling so you'll be stronger all the way until 6 items.

Alistar

Similar to hook champions but harder to dodge Q and W so it actually requires some skill.

Varus

Slightly Ezreal favored because both want to poke but Ezreal can more Qs than Varus. Basically hit more Qs than him and you'll be good.

Brand

Outranges you so can easily poke you down and outscales you aswell.

Miss Fortune

Has a ton of kill pressure on you but if you position well and keep her at a health disadvantage, you'll beat her in lane and outscale her. Stay aware of her R at all times because even from behind she can wipe you and your team in seconds with a well timed ult.

Sivir

Not hard to play against but you can't kill her because of her spell shield and range. You can only beat her if she misplays but she's quite easy to not int to.

Jinx

As long as she doesn't get ahead it's a pure skill matchup.
