This list contains data from Diamond level Korean solo queue over the past month. Master and Challenger specific champion picks which had high win rates and would’ve made the list were not included because of the very low number of games played on these champions. I decided to include 5 more champions in this list because 4 out of the top 5 champions have a small number of games played.
