It's just my dream leak. Don't believe it, but if you want you can.

-It would be cool an important role for Ryuki, more than Gladion!
-Crobat and Granbull alolan form, dark/flying and fairy/fighting, maybe?
-Every pokemon is following you! But I don't think every legendary one will...
-new z bracelet increases pokemon stats... It would be awesome.
-new elite 4 and new clothes.
-ancient magearna *-*

I hope this leak is getting real.
