just a few things id change, for one cd blues are better imo cuz it makes him a much better harasser, also unless u waste mana as fast as u can and cant conserve mana when its easy to then Manamune is un needed and ghostblade should come later in build if at all cuz brutalizer is better to just keep and then get other items instead. if you play urgot well then mana isnt really a prob if u have ur yellows and masteries with mana regen

It's a nice build, even though it's pretty standard. A few spellingmistakes that you may want to correct and I think it also would be a good thing if you explain that, unlike gangplank's parrrley, Acid hunter does not apply on-hit effects other then your shield. This also lowers the use of lizard buff for urgot, and you may want to give it to another ranged carry instead.

I personally prefer to change the yellow and blue runes to something a bit more defensive, since you're diving right into their team at times. Since you use secondary and tertiary runes, the benefit you get may be less thenwith other runes.
