So, we know that at the every saga ands with the league (Indigo league, Orange league, Johto league, Hoenn league, Battle Pyramid and Sinnoh league).
But now, the Unova league is over and the saga is still going on. What would you think will be the end of the saga that will have as much impact as the league? What epic end can replace this?

This saga can't end with nothing special. The league shows Ash's progress from the very beginning of the saga until the end. What can shows that instead of the league?
