Which champion has the most timeless kit?

I was having this discussion, with friends, and I'm curious to hear your thoughts. Which champion has the most timeless kit?

By timeless, I mean which kit has had the least amount of changes or reworks, but is still viable in almost any meta? Solo Q and pro scene.

For me it's either Thresh or Lee Sin. As far as I'm aware these two have only had minor quality of life changes, and the obvious occasional stat buff/nerf, and have always showed up at least once per season in the pro scene.
