Better not cheat...I think we should wait until the real event comes.
The event's already come, smart one. =/
If they don't have another one, I'll be mad.
Celebi is the 'Mew' of GSC; I doubt there will be any event for it in GSC, but there's a good possibility for DP.
Well, there haven't been any events for Pokemon S/G/C in years, so the only way to get Celebi would be to cheat. If you don't want to cheat, then, I don't know what to tell ya.
@Brotlov: Multiple types? What are you talking about?
