I've been playing AD Blitzcrank for some time now. It's an incredibly successful strategy. Most people don't suspect the damage that comes from it. Its best that you play this build top but it can really work any lane, even jungle!

First thing you have to do is rush sheen. The sheen effect is essential to this build. Also at the begging you can get boots but, when you get full build you want to sell them to get one of the other items. It doesn't matter what order you get the items as long as you get trinity force first.

You are going to want to be offensive with this build. You don't want to engage with your q as with most blitzcrank builds. You want to run up and hit them once with an auto attack then hit them with your e. It works best with the sheen. As they get farther away and you can't auto them then you pull with your q. You don't max the e first because the ad damage doesn't increase with upgrading it. You want to use the e most of the trade if you can.
