THANK YOU! and disclaimer
Thank you for visiting my guide. THIS IS A BIG W.I.P, and I appreciate any and all feedback the community has to offer. I am starting this guide very early on (Bronze lol) because I figured it will be cool to update as I climb (IF I manage to climb). So take this as a Bronze-elo/Elo-hell guide, just kinda what's been working for me.
I will be adding illustrations to make my thought processes easier to understand.

About Clytt
I am a level 7 mastery w/ <100,000 points. I've learned to lane against most champions and team comps with Ezreal and believe to have built up more game knowledge than most of my elo-hell opponents.

LINK: Here is my League of Graphs profile for Ezreal Mid

Valid concern.

Traditionally, Ezreal is played as an ADC in the bot lane with a precision keystone, like PTA or Conqueror. I believe he crazy scaling potential when alone in lane. Not to mention there are more effective ADC champions that can afford to scale with a support (ex. Caitlyn, Lucian). Ezreal can survive the early game just fine (probably better survivability than most mid picks) and doesn't need another champion in lane to support him. Ezreal is one of the most fun and dynamic champions in the game. I'll give ya a list of reasons why Ezreal Mid but most importantly: UNLIMITED CREATIVE POTENTIAL!

[*] Zones like a madman with poking ability, especially after Essence Reaver. You can EASILY make the enemy roams a waste of their time by positioning and then repositioning well. They won't come back once they realize their roam wasted so much time, they have to back bc we poked sack, and their laners are scaling w/ uncontested CS and XP. Side note: enemy bot lane rarely roams at Bronze elo, but if they do, make sure our support knows to follow. This is necessary for several reasons:

1. Most importantly, allows our ADC to scale on their own. Very very very importanty. Support can do their job with a level disadvantage, ADC absolutely cannot.
2. Needs to be there incase they attempt a tower dive w/ their jungler, mid, adc, and supp. Our elo tower dives are usually terribly uncoordinated and we should be able to pick up a couple free kill/assists from their mistakes.
3. Provides opportunity to deep ward the river, helping your ADC (who is scaling alone) know when enemies are coming back.
4. Can quickly transition to a drake objective if timing and vision is right.

[*] AD/AP Hybrid - can 1v1 anyone mid-late game

[*] Shotcaller/Quarterback - control objectives, ganks, pushes, etc.

[*] Quick access to all lanes and all 4 jungles - more farming/scaling potential.
Mid is a perfect area of the map to play around with our mobility advantage.

[*] River walls + E allow us to get in/out of situations (without burning flash) yet still poke like crazy through terrain. If you land a few Q or W+Q pokes on the enemy jungler while they're rotating through mid bushes, your jungler can capitalize and get you a kill/assist. POV big boy voli stomps his from top riv to bot riv to contest scuttle + you have vision bot riv bush -> shadow his pathing from the other side of the wall, poking several times. Get him low (and ping like crazy) enough for your braindead jg to feel comfortable engaging. Depending on how it goes, you have option to E over wall to finish him off. OR (maybe more importantly) zone off your enemy midlaner (A.K.A scare him away from joining the fight) by poking them as well.

[*] Incredible survivability = does NOT need a support champion in lane. ATTENTION JUNGLERS: please still gank tho :) I ward a lot, I promise.

[*] to be continued...

Teleport + Flash (Take vs. Mages)

[*] I take almost every time because one good teleport can determine the entire game. Great for farming and dodging enemy abilities until you've saved up enough for first back items (ideally Caulfield's Warhammer + Tear + Control Ward = 1,575 gold; 1,225 gold if you start longsword).

Exhaust + Flash (Take vs. Melee)

[*] Exhaust has infinite situational potential. Take it vs. melee champs who can all-in before you have the chance to scale ex) zed.
[*] Also great against other ADCs that think they can play mid. You can win lane early if you manage to poke them to around 1/2 hp center lane then pop a combo. Wait for them to use a key ability (ahri charm) then punish them if they miss.
[*] W + E then exhaust -> AA -> Q repeat. It makes landing skillshots 1000% easier.

First Strike

Every time. We end up making soooo much money from First Strike, allowing us to scale faster. Save 300 on the boot purchase + a permanent 10 MS? Automatic. More sustain with biscuits + presence of mind? Allowing us to keep up passive Maximum Spell Force and poke the living daylights out of the enemy midlaner? Automatic. Still is.
