I have played this on my gold smurf a lot and ad ahri works a lot better than most people would think. I recommend starting a tri force though. It gives her a major power spike once the item is complete, allowing her to assassinate as if she had built ap and still play for the long game of ad ahri.

I actually invented an ADC Ahri build. It focuses more on attack speed and life vamp, which I have found to be insanely useful. Ahri is entirely viable as an ADC

Well....how about if our support already take Exhaust, should i also take the Exhaust?

oh yeah urgot is the tankiest ranged

Well, i was working on an AD Ahri guide myself, but dropped it. Probably I'll finish it sometime. I'd say yes to AD Ahri, but no to this guide. For runes id really take flat armor yellows, and flat/per level mr blues. It is better in early and in late game.
The skill sequence is...well it is not my style. I always run r>q>e>w and don't give a point to Fox-Fire untill the very end. Orb of Deception is much easier to land and gives you a lot more harrassing power. It also makes sense to max it first because your auto hit damage in early is not high so the longer duration of charm isn't scaling as good. Another reason is that she gains a bit more sustain by maxing Q because she can use a bit more of her passive (even if its not that big deal.)
The masteries are what I'd also run if I'll take Exhaust over Heal/Cleanse.
Items: well I'd say you should buy always Infintiy Edge, Phantom Dancer, Last Whisper, Berserkers Greaves, Bloodthirster (/in early can be replaced by Wiggles Lantern, later you should sell Lantern and go for BT anyways). The order and last item can be changed depending on the Situation. The last item USUALLY should be either Quicksilver Sash, Guardian Angel or sometimes Banshees Veil. QSS to cleanse CC, and its also very cheap. The usual build. GA if the other team has not a lot of CC and if it has not a lot of magic damage. Can be used quite often. Banshees Veil to block skills. For example Gragas or Orianna. Usually you should not buy this.
If you are playing a Double AD Team bot+top lane you should also run Black Cleaver instead of Last Whisper but it is very rarely played although it makes sense if you run AD Ahri Bot lane to get a common AD pick in the Top lane (Ezreal, Corki, Kennen, Graves can do very well there).

I think this could work really well if played properly

Well I honestly dont think she gets outclassed by anyone, ESPECIALLY if you have a support with you that also has a stun. More range than Graves, and at the same time still has an amazing disable

Ive played AD Ahri alot and have to say its very fun and surprisingly good :P It is outclassed earlygame by Graves, and outclassed Lategame by almost every single ad carry, but for normal games its surprisingly viable and strong :P

FYI, If you enjoy this build but want something that is more viable, try AD Kennen. It is better, W stacks with AD and doesent fall off. double stun in lane is OP on a ad carry :P +1 for ad ahri!

Hahahahah WUT

Interesting very interesting. I'll have to try this out. :D
