Ad Kayle?

I started falling in love with kayle a week a go and I've been spamming her having a lot of success building nashor into dusk and dawn then typical mage items, but then I wondered. Is AD Kayle viable? I've seen Kayle 1v9 play it several times and he's got a lot of success. But I don't know when to build it or how, or even if it's worth it? I'm talking about yuntal kraken and such. Let me know guys thanks!
