Oh, a new Mythical? Cool. I love Mythical Pokemon. I'm sure it'll be available through the free update, at least. I hope it's not as boring as Magearna, though. I loved Marshadow, Meltan and Zeraora from the last generation. Those were really cool.
I heard a youtuber theorize this new Pokemon will be promoted during Pokemon Day in Max raid battles? I honestly highly doubt it's gonna be locked behind the dlc or Pokemon Home.
Honestly, I really hope the Pokemon GO related thing, I hope it's Kalos Pokemon finally being added? We'll see.
