The Tapus being still shiny-locked is sort of a disappointment, but I guess it's understandable story-wise. Still no excuse to shiny lock Zygarde or Magearna. Not like I care that much about them, though, since the regular Zygarde looks way better to me, and Magearna looks exactly the same unless it's original color.
Still glad the UBs and past gen legends can be shiny. Time to get neat stuff on Beast Balls!
And...
Yes! Even though Pidgey line isn't in the Alola Dex, I'm sold with them being legitimately obtainable in Beast Balls!
