I think you misread what I said, because you basically repeated what I said. You should be able to get any Celestia Pokemon in your own game yourself unless it comes from an event which specifically states otherwise
or if you're trading with another player. I suppose if I traded my Plusle for Eti's Garchomp I could get my own Garchomp and he could get his own Plusle in his game, if that's what you're trying to say, but that defeats the whole purpose of a 'trade'...and really probably shouldn't be allowed if it is.
