Next level Champion mastery Concepts

I think with the new clash system we can add a new level mastery for the champion, just look like we can add solo battle or 1 v 1 battle with the same champion such as Yasuo tournament where you can test your skill using your favorite champion, I think. And If you win this tournament you will grant some BP and EXP as well, and a Mastery token that you can use to upgrade your champion's mastery. This just still a concept and if you agree with me or have a question you can ask in the comment
