Aww, darn. >0<
What other events/shinies do you have? More specifically, I'm looking for one of these:
UT Celebi (I don't think the event matters), UT Suicune, UT VGC Shiny Milotic, or a UT Chansey w/ Wish with a Calm or Bold Nature.
These aren't the only ones I'll accept though, so if you don't have one of these, we could probably work something out.
