Hmmm, I would like to add AP Corki, it is pretty much the same case as Ezreal and Kog'maw, and potentially even a stronger AP champion.

3 of his ability has AP ratio (especially the hard hit phosphrous bomb which hit like a truck in any part of the game)

Ultimate can also hit for a lot with AP, spammable and can proc Lich Bane as frequent as Ezreal can.

AP Corki is nothing new and is somewhat popular, you just probably forgot about it
