I've played Ezreal, time to time in ranked, and win 70%+ of my games as him. He CAN demolish teams, but if played wrong, can be obliterated. This guide will focus on an aggressive type of play style, and will require some balls.

Pros
-Huge Damage out-put
-Free AS
-Mini-Flash
-Q applies on-hit abilities(Sheen!)
-Global Snipe ult
Cons
-Squishy
-No CC (wahh!)
-CC destroys him
-Very hard to master

Let's jump into it with MASTERIES!

I run a 21/0/9 because I focus on huge damage output. Armor Pen, Crit, Physical Dmg, what not to like?
Also Viable
9/0/21-9%CDR with a bunch of movement speed as well.
23/1/6-All good offensive masteries, and with some MR.

Greater Mark of Desolation Armor pen is always good, and it also applies to Mystic Shot(I think)
I like AD, simply because it has good synergy with your passive
I like CDR for the shorter CD of Q and E.
I like AD.

Exhaust and Ignite give me the necessities to play aggressively. It almost always nets me first blood.
Other Viable Spells
Good escape spell, but you already have E
Same thing as Flash, but it is a bit worse
You get focused fast. Sometimes good, sometimes bad.
Spells that are Bad for Your Health
Why oh why kind sir do you get this? You shouldn't be hitting W in most cases and other wise you are FINE
Please. The only OK thing is heal baiting and that's it.
Do I have to explain?
Leave this for supports.

x2 For lane dominance and survivability in lane.
"Oh no, why this?" you might ask. Sheen helps your damage so much by using an amazing combo of E>Q>auto-attackx2>Q>auto-attack for some heavy burst.
=> CDR boots let's you Q more and more and E more and more and Ult more and more.
This badboy helps you deal lots more damage.
I like more damage, don't you?
Damage Items
Last Whisper This rapes tanks
Madred's Bloodrazor This too, owns tanks
Bloodthirster More AD and Lifesteal can't be bad
Infinity Edge Omnomnom I like damage.
Defensive Items
Banshee's Veil Fed casters omnomnom you if you don't get this
Quicksilver Sash Get out of ammumu ult/ karthus ult/ vlad ult
Guardian Angel Oh wait i'm back to life. More damage nao.
Frozen Mallet Can't go wrong with a slow and damage and health.
Before a Fight
Elixir of Fortitude
Elixir of Agility

Pasive: Rising Spell Force
Hitting a target with any of Ezreal's abilities increases his attack speed by 10% for 6 seconds (Max Stacks: 5).

Great passive IMO. It helps push towers easily, just shoot Q into the minion wave and give more AS. In teamfights, ult=almost full stacks.

Q: Mystic Shot
Ezreal fires a bolt of energy dealing 40 / 65 / 90 / 115 / 140 plus 110% of his attack damage and 20% of his ability power as physical damage (applies on-hit effects).

Ezreal's cooldowns are reduced by 1 second if Mystic Shot hits a target.

Cost 30
/ 35 / 40 / 45 / 50mana

Range 10000
This spell has EVERYTHING:Long range? Check. Damage? Check. Cooldown low? Check. Free CDR? Check. Every teamfight, this spell amazes me. It makes your blink come on A SUPER LOW cooldown, as well as your ult. Poke fights you win 100% because of this.

W: Essence Flux
Ezreal fires a wave of energy that damages all enemy champions it passes through for 75 / 125 / 175 / 225 / 275 (+60% of ability power). Affected ally and enemy champions have their attack speed respectively hasted or slowed by 20 / 25 / 30 / 35 / 40% for 5 seconds.

Cost 60/70/80/90/100 mana
Range 10000

His worst spell probably. Mana drainer, and it's only good for 1v1. (generally, since in teamfights, it's hard to hit carries with it.

E: Arcane Shift
Ezreal teleports to a target nearby location and fires a homing arrow at the nearest enemy unit dealing 80 / 130 / 180 / 230 / 280 (+75% of ability power) magic damage.

Cost 90mana
Range 10000

I love this spell. This is why I don't take flash. Ok nuke, but you can traverse walls. If you teleport on the wall, it will send you to the other side. (It was better before b/c you could E a ward)

R: Trueshot Barrage
Ezreal channels for 1 second to fire a barrage of missiles dealing 350 / 500 / 650 (+90% of ability power and +1 per bonus attack damage) magic damage to each unit it passes through. However, it deals 8% less damage for each unit it hits (Minimum 30%).

Cooldown 80 seconds

Cost 150 mana

Range 20000

Have you ever been sniped by a yellow bot of energy out of nowhere? This is it. It's so fun to use, and it's a GREAT finisher. You can crush squishies now, b/c it stacks with AD, and you can steal buffs this way, push lanes this way, and so much more.

I almost always face a AP caster in midlane. I love this. You can harass them all day long with Q, and unless they have a long range, you gain lane dominance. At level one, I go for first blood right away. It they overextend, boom I deal them a Q>Auto-attackx2 combo for 40-50% of their hp. As soon as I hit level two, it's much easier.

What you want to do, is to E behind them (or beside them, it really doesn't matter). What does matter though, is that you hit your Q. Then exhaust, ignite, auto-attackx2, then Q and they should be dead. Boom, firstblood.

But mostly, focus on farming until you have enough for a sheen and boots of speed. If you have to go back early, pick up another doran's and boots.

Ezreal really starts dominating here. I usually have 1-2 kills against a silly caster, and am very strong now. I usually have 2x Doran's, Sheen, Boots of Lucidity by now. You should really be aiming at getting that first dragon now. You will do so much more damage than a carry at bot lane, so it should be no problem getting dragon.

You want most of the red buffs after the first one, to increase your damage. I have found I am ALMOST unstoppable with it. Near the 20 minute mark, you should aim for having Sheen, Lucidity, and B.F. Sword and Vampiric Scepter. Maybe you'll even have Bloodthirster by now, but only if you are fed.

This is where Ezreal starts to fall off a little bit, but still, he is very strong. You item goals by the end should be an ideal: Trinity, Bloodthirster, Boot of Lucidity, Banshee's Veil, Last Whisperer, Infinity Edge/Madred's Bloodrazor. This build may be very expensive, but you should be farming very easily with Q and auto-attacks.

In teamfights, positioning wins. You team position should look something like this:
Tank Bruiser
Support Caster
You

At the beginning of engagement, Ult and try to get everybody, you probably won't, as they won't be standing like this:
Tank
Bruiser
Caster
Support
AD
Alternate Q and auto-attacks like this: Q>2 auto-attacks
Use E if somebody like Nocturne goes, "mmm, tasty squishy."
Also use E to kill someone. Remember, E also does some damage.

Play Video This video shows just how powerful Ezreal is, and Colbycheeze is such a great commentator. A bit outdated yes, but it's just AWESOME. Play Video Domination of Win10cent. He is just so good at Ezreal.
