Yeah that is what I'm hoping too. I mean the FR/LG games got some events (Navel rock and Birth Island) so why not let HG/SS get something too? I'd imagine it would be rather similar to the in game Shaymin, Arceus, or Darkai. Also it seems that Celebi is the least common available event pokemon right now. So making this a wondercard event would make it about as common as other events.
