Official Rulings for Infernal Denizen
10/4/2004 : You should always have one creature for your opponent to take (i.e. the Denizen). If by chance you have no creature for your opponent to take, then they don't get one. Remember that taking a creature is optional so your opponent is not forced to take the Denizen.
