My tier list of champions lol, as long as you want to base it on the champions' game stats have a look at https://loltierlist.gg/tier-list they list the champions according to their win rate.

swain which is a very good support because of its magic damage

And Karthus ADC which is in top winrate on the site I mentioned.

However, note that winrate isn't everything
