IM UPDATING AFTER A LONG TIME, BE CAREFUL AND DON'T FOLLOW THIS BUILD BLINDLY

UPTATED

OUTDATED
Introducing to you, ladies and gentlemen. The new Ezreal!

Ok, you may be thinking what kind of "ridiculous" build is this, but it works and works really well. I will explain it all while you scroll down the whole guide.

First, this is called the blue build because of the items... They're blue, but not random blue items, they are really well chosen blue items. with full build you will be using your Mystic Shot each 1.5 sec and each of those Mystic Shots will be dealing 500+ dmg and an 200+ AoE around the enemy hit and this doesn't counts auto attacks and the other skills.

UPDATED

Pros + Great poke + Aoe slow and damage + 500+ dmg on each Q + Has a true damage dps.

Cons - Farm dependant - Muramana drains mana heavily. - Mana/Blue dependent - Needs a skin to be blue

UPDATED

• Rising spell force: This passive allows Ezreal to turn into an AD carry even while using an AD caster build, 10% atack speed per stack is always welcome ^_^
  
• Mystic shot (Q): Your bread and butter you will use this skill more than your auto atacks when you get the 35% CD reduction, dealing "tons of damage" each 2,44s (1,44s if you hit). And this skill also reduce the CD of the other skills in 1s wich means your Trueshot Barrage will be more "spammable".
  
• Essence flux (W): This skill will be leveled last, dealing almost no damage before the Iceborn Gauntlet, it can be used to proc the Iceborn Gauntlet but it also has a nice attack speed buff that can help any ADC or champion that depends on attack speed.
  
• Arcane shift (E): Your escape and chase skill, not recommended to deal damage, can also be used to stack your passive, avoid using this skill to chase.
  
• Trueshot barrage (R): Your ultimate, can be used to farm, steal baron/dragon and get/steal kills, it has 80sec of cooldown, but can be reduced by CDR and by hitting your (Q) Mystic Shot.

Essencial Items

More cooldown reduction, so we can spam our Mystic Shot with more frequency. Less cooldowns, more Mystic Shots, more damage. I can't imagine a better boot for this build.

True damage dps on all your skills and auto-attacks, why not? it's a red buff that isn't a red buff but stacks with red buff, just perfect.

More damage on your skills and attacks, i recommend toggling it off when you have less than 40% mana so you can still spam. also it grants a fair quantity of attack damage

Offensive items

Gives you life steal and some advantage against tanks, also makes your Mystic Shots deal some nice % damage

You have armor? i don't care.

Defensive items

Gives you armor and ap, this is why you will use the spellsword mastery, also gives you blue hands an AoE on your Mystic Shots

gives you armor and magic resist and you also revive after dead, but Iceborn Gauntlet grants enough armor. i don't think it's necessary

more mana and armor, useful against heavy ad and auto-attackers also the extra mana is transformed into damage trough Muramana

Tips:
[*] If you buy Frozen Heart or Spirit Visage, you can sell the Spirit of the Elder Lizard AND get Trinity Force (sell Iceborn Gauntlet if you buy Trinity Force) this way you will keep the max CDR%.
[*] This build is op because of the cooldown reduction, if your item mix doesn't give 35% CDR then you're building Ezreal the wrong way.

UPDATED

The changes are:

ALMOST FINISHED UPDATING! (usable)
With this build Ezreal turns into an AD Caster, when playing with this build spam Q Mystic Shots, and use your E Arcane Shift to escape, W Essence Flux is useful for stacking Rising Spell Force and to increase allies attack speed when destroying turrets OR to shut auto-attack dependent champions like: Vayne / Irelia / Xin Zhao / AD Sion / Kog'Maw / Jax / Aatrox etc.

That's the guide, I'm still building it and updating
