New Idea For Versitile Champion

I think league reallly needs a champion with the standard Q W E abilities, but i think their ult should be one that is adaptive, and what i mean by that, is that we need a champion in league whos ult is literally to mimic someone elses on the battlefield.

Enemy team has a soraka? now you have a soraka ult Enemy team has a karthus? now you have a karthus ult Enemy team has a yasuo? well you fucking lose so it doesnt matter
