A variety of Ezreal builds, all of which are viable, whether or not they appear to be.
The first 5, the "More Standard Viable" builds, are all accepted in casual solo queue play and are not considered troll setups. The second 5 may seem particularly trollsy, but rest assured that they are all actually viable; they just appeal to different ways of playing Ezreal, taking advantage of his strengths in ways almost entirely unexpected by the LoL community. Hopefully you find this guide as useful and amusing as I find it to create.

Cheers.
