This build is fairly simple and incredibly powerful. It focuses on every on hit effect damaging item in the game combined with champions who have a skill or passive that compliments it. The four above are the best compliments to this build.

The idea behind this build is to whittle down the opponents hp very fast, regardless of magic resist/armour/hp.

Said above, these champions are amazing compliments to this build for two main reason.

Teemo: Passive poison on his E acts as another on hit effect for his auto attacks.
His blind- of course is very effective vs ad champions.

Twisted Fate: Combo-ing Blue card, Stacked deck and SoD at the same time will cause heavy damage early game and of course scale well into late game.
He also has his stun yellow card.

Vayne: Has her true damage from silver bolts and amazing pursuing capabilities.
She has her stun as long as you hit then into a wall.

Kayle: IMO the absolute best for this build has her E which acts as an on hit effect plus splash. She also has her Q to case targets to take increased damage and her passive which rips apart mr and armour. Why I think she's the best for this build is simply because of her ultimate. Yes her ultimate, and all the stuns and blinds from teemo, vayne and tf range from 1 to 3 seconds but keep in mind that you are attacking 2.5 every second.

For all of the champions you want to focus on the skill causing extra damage.
Teemo: E->Q/W->R
TF: E->W->R->Q
Vayne: E->Q->E->R
Kayle: E->Q->R->W

Summoners:
On all my ad I prefer to run cleanse and exhaust.
Cleanse to get rid of exhaust or other stuff
Exhaust to make a kill easier

Masteries and runes are geared towards maximum starting AS.
The order of buying items is not specific, I like to go Maladys/Beserkers-> Wits end etc

Sorry for such a bland looking build, it's my first but I'll get better as a post more.
Note:Recently I have seen people start to use something similar to this since I used it many months ago but I'm not implying anything.
