Would you like to trade Pokemon temporarily?

So like the question says, I recently got Pokemon White and i would like to get Zorua but i can't do that since i did not get the Event Celebi(With the Fateful Encounter status on it), What i would like to ask is if anyone with Pokemon Black or White would be willing to temporarily trade that Celebi so I can receive the Zorua? I shall return the Celebi once i am finished which shouldn't take too long.
