If there are no creatures your opponent controls to target at the beginning of your upkeep, ignore this ability. [D'Angelo 2000/02/25]
If you have more than one Djinn, you can have all of them target the same creature with their ability. [D'Angelo 1996/12/10]
In multiplayer games you can choose a different player's creature each time it is used. [Duelist Magazine #4, Page 64] You are forced to pick a creature that some opponent controls if there is at least one creature in play that is a legal target. [Aahz 1996/06/13]
