This is a build I have been testing out and has done well for me in the past. Test it out for yourself and comment or upvote it if you like it. Thanks!

The Runes are just basic AD champ runes feel free to add your own spin.

I have these masteries just to get as much AD to start as possible. If you get the early kill in lane (especially solo Top) you will for sure win the lane. Early Game Lane dominance is key.

These Items are to try and maximize your damage out put and attack speed while keeping you somewhat tanky. Variations off of this would work well too.

You could also try Teleport for solo top rather than Exhaust, but again we are trying to get as much damage out as possible. Ghost would work as well to close the distance when you ult or chase. ITs really up to you and what your play style fits the best.

With this build I hope that you can get the early game kills while also getting great farm to buy these expensive items. Don't forget you can leap out of bushes or while stealthed so use that to your advantage in ganks, attacks, and chasing down for the kill. (Your ult even unstealth's invisible champs, including another ulting rengar. Good Luck
