Hi,In this build ill show you how i build Ezreal.
I hope you'll use my advices on the Fields of Justice :)

Rising Spell Force Hitting a target with any of Ezreal's abilities increases his attack speed by 10% for 6 seconds, stacking up to 5 times.[/img]


Mystic Shot Ezreal fires a bolt of energy dealing 35 / 55 / 75 / 95 / 115 (+1 per Attack Damage AND +0.2 per ability power) as physical damage (applies on-hit effects). Ezreal's cooldowns are reduced by 1 second if Mystic Shot hits a target[/img]
-I max it ability first as its only ability that stacks with AD.
Essence Flux
Ezreal fires a wave of energy that damages all enemy champions it passes through for 80 / 130 / 180 / 230 / 280 (+70% 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.
- I get 1 point of it at lvl 4 to keep mystacked up othervise maxing it last.

Arcane Shift
Ezreal teleports to a target nearby location and fires a homing arrow at the nearest enemy unit dealing 75 / 125 / 175 / 225 / 275 (+75% of ability power) magic damage
-I max it by lvl 13


Trueshot Barrage
Ezreal channels for 1 second to fire a powerful barrage of energy missiles, which deal 350 / 500 / 650 (+1.0 per bonus attack damage AND +0.9 per ability power) in magic damage to each enemy unit they pass through. However, it deals 8% less damage for each unit it hits (30% minimum damage).
-I take it whenever availible like other ultis.

Pros:
Essence Flux can be used to push tower easy much as help you to deffend yours.
Mystic Shot is extremely low coldown with items i suggested so with alot of Mystic shoot using youll get you bonus dps easy.
Arcance Shift is like a 2nd flash.
Trueshot Barrage is global
Cons:
Arcane Shift has low range
Mystic shoot is single target attack and its pretty easy to avoid
All of your abilities except ultimate are tiny and are extremely easy to avoid.

Well,Ezreal cant jungle.
I dont even suggest for you to creep on him.

Use yourwhere it can get trough most of enemies or use it toget multi kill when enemies are retreating to their base from teamfight.
Use yourin right direction so it can increase and haste DPS.
Follow the fleers withandonce your in range cast urand make them easy target for your team.

If your going with tank go with Mordekaiser,He can easy take bunch of damage while ur farming back.
If your going with support go with Sona or Janna for Ad buff.
Also Karma can be good teamate to you if your planning to play very aggresive.
If going with fighter go with Jax or Garen they have nice AoE damage.
Also silencing enemy with Garens silence will make sure your enemies cant use skills to avoid your ultimate.
If your soloing 2 stay in brush and farm.Also save your[/img] for getting other lanes kills becouse you wont get many in your lane which is 2v1.

Open up withGrabandfor cooldown reduction and attack damage.
After Cooldown reduction and AD you need some DPS.But not with items likebutis ideal becouse it already gives AD and DPS.Why not more cooldown reduction?Becouse your rune set-up already gives you full cooldown reduction.And once you do have Cooldown reduction stacking yourfor even MORE attack speed.
Adonitially graband. Becouse both of those have on-hit effects that will greatly improve your

spell will help you winning 1v1 fights.is bonuswhich comes useful in cases like when LeBlanc in this case jumps over the wall with.You follow her wiithbut she usesand jumps over another wall.You dont have enought time for your coldown to refresh and you lost a kill.
If you had ayoud Catch her up,Good going :P

I take all attack damage caster masteries in offense.
While increasing my mana regenaration in utility much as i can

is your main farming spell becouse of its low coldown and big damage.
Allways be ready to use it!

Useto use yourand useon allies instead of enemies becouse they need bonus DPS more then you need to do some low damage on enemy since your not building AP.

Thank you for reading this build i hope you gonna have use out of it Thx again :)
