I used to use a build very similar to booshido's AD Ezreal build, but after the mana regen nerf I found it tough to farm and harass. This is a variation that includes manamune so mana regen runes are not necessary. Because you get phage a little later in the game I opted for health per lvl seals instead.

I'll come back and refine this guide later.
