Azir ADC?

Not ADC. APC. Get a Nashor's Tooth and then build full AP. If you play him right then you have huge consistent DPS from the back line. Kinda like an ADC, but with AP damage.

I don't own Azir but to my knowledge none of his abilities scale off of AD. He's still an APC, he just functions like an ADC is all. I don't think there is a particular build that works on him for AD. But try it out if you're curious. People are finding out new things every day.

"Marksman" is supposed to do consistent DPS. They don't necessarily do physical damage, but AA is the best source of DPS, so most marksmen are ADCs. Azir, Teemo, and Kayle can all be Marksmen depending on how you play them, even though most of their damage is magic. I'm reluctant to call Cassiopeia a marksman, even though she has a really low cooldown spell that basically works like an ADC's AA. Heck, it even gives you some HP back, just like lifesteal.

APC. It's just normal Azir, with his AP. Seriously, good luck to the enemy and their Cs'ing endeavors.

I've played Azir bot lane quite a few times. Since you usually have to heavily trade in the bot lane you'll go oom very easy if you just straight up rush . I think the strongest build for bot lane Azir is going . The early so you can constantly trade without going oom plus he can stack incredibly easy. This also gives him the most dmg out of any other build, but the downside is that it does take awhile to scale. However, that's not really a problem if you play him bot since most ADCs need a few items to get going.
