the anime should have let Ash catch Diancie if they wanted to give him a mega that much in XY instead of that shitty frog
>B-But Ash isn't allowed to catch lege...
first Diancie is a mythical
second this "rule" was stupid to begin with since he eventually gets a melmetal in Alola
>B-But then it would be literally impossible for him to get Burasto Ban?
Well yeah thats the point, it was poor decision to make him lose this league which is why they get rid of him after Journey, if Ash won the Kalos league, journey would never happen.
