Welcome to my unranked/ranked ezreal guide.
Here is a screen shot of what this build can acomplish.

The items are all pretty specific, unless the enemy team has a lot of armor. I will then swap the infinity edge or guardian angel for a last whisper.

Flash-I use this as a gap closer or to get out of sticky situations.
Ignite-I use this to secure kills early game.

During 1v1 fights, I like to to arcane shift towards the opponent the essence flex then mystic shot, i only use true shot barage if neccesary.

During team fights I like to open up with my ulti then spam my mystic shot and essense flux as often as I can.
