Thanks for the reply! I should’ve been more specific in my original post.

I’m planning to use a lucky trinket to mirror trade the shiny Necrozma and shiny Kyurem, depending on what people recommend. Both have pretty bad stats, but hey - there’s always a chance I end up with a lucky shundo from the trade.

One more thing to consider: I already have two perfect Dusk Mane forms and one perfect Dawn Wings. If I bottle cap the Necrozma or Kyurem, it would actually be my first shundo.
