In this build you see ow to play Ezreal for dealing damage and be fast for got out of danger.

Excuse me for my bad english but i am from Germany.

If you have the 23/0/7 Mastery tree, you will deal damage and you wont have manny porblems with mana

With a good attackspeed you can farm without problems. If two minions are low at the same time auto-attack the farther one and shot your mystic shot the nearer one. You will get the Gold for both.

When you are low and have to go back but you dont have engough money wait for the next minions wave and hit all with you ulti now all minions are low now use q,e and auto-attacks for getting gold(in higher level you kills all).

With the Lantern you have lifesteal at start so you dont have to go back so often and earn more money. It is good for your amor too!! All 3 minutes you have a ward if you click on the lantern.
With sheen for trinty force you can use Ez´s own flash and your mystic shoot is dealing 100% more dmg(sheen) or 150% more dmg (trinty force) Bloodthirster and the Ghostblade is for deaking more dmg and with phantomdancer you are fast with one of the slowest champs.(Mobafire says this build has 375 but i had with this build 465) In late game you can sell your boots for one more phantomdancer. And you can sell your Latnern for one more bloodthirster too!

In teamfights you have to fight in the background you die afther 2 to 4 hits so its important to deal damage and got far away of enmies.

Use your W on your partners to raise their attackspped.
