As far as I know, Corki is a viable ADC. As you stated, great escape, good damage, generally even so with the nerfs and change to Phosphorus. I think people dropped him because of the general "Oh no, he got nerfed (very slightly), now he's trash" attitude for every champion.

Alistar is actually useable. He's a really hard counter to Leona and possibly Thresh as well. That said, I think that's all he has. I went Soraka vs him, and I did pretty well.

Karma I have no idea why. I think it's because she has a great poke in Q, but that's it. Her W requires being close, and it's a DoT. E is just a shield.

Zilean I don't know why either. His bombs are stupid to play against, he can slow you down, and his revive Ult. That said, not enough damage, and many champions now have mobility that isn't restricted by slows (Dashes, Blinks, ignoring slows.)

Nunu I think suffers from identity crisis (AP mage? AP Tank? Tank? Jungler?) Not sure if he can still, but previously he was able to solo dragon and baron ridiculously early. He still is annoying as crap in a Duo Bot lane with another AP character (Just throw pokes at the adc and scare them away from the lane.) His E is kind of broken too, with it's high base damage, 1.0 AP scaling and low CD. It's range is comparable to most ADC's too.

Talon I think fell out because of all the AD bruisers going mid. That said, he counters almost every AP champion mid, and his E has little to no counterplay.
