Hello, this is my first build guide. This is basically an aggressive Graves build guide, and the best build I could come up with.

Ghost and Exhaust seem to be the most effective summoner skills, flash is impractical considering you already have basically a flash, and ghost can make up for his extremely slow speed.

I play an extremely aggressive Graves, but don't see lifesteal as an important stat until mid/late game. He has good sustain due to mp5 and Doran's Blade, and avoiding lifesteal until a little later and going straight for damage seems to be the most viable option as Graves. I don't get Black Cleaver on Graves because he seems to auto attack less than champions like Ashe and Xin Zhao, who seem to depend on Black Cleaver the most.

This goes without say, Graves' Buckshot is extremely potent in damage dealing, as is the utility of Quickdraw, so I max out Buckshot first, and then Quickdraw. I don't get Smoke Screen at 3 because I don't see it as utility based in terms of aggressiveness, however the slow is extremely helpful, so I get it at 4.

Con's-
Very squishy early game.
You have to get really fed in order for him to be any use.
Pro's-
Buckshot does phenomenal damage if lined up right.
Smoke Screen is really effective against other ranged AD, and excellent for chasing/escaping.
One of the best 1v1 champions in the game.
Good lane sustain if played right.
