Creature - Demon 5/7, 7B (8) At the beginning of your upkeep, sacrifice two Swamps. If you can't, tap Infernal Denizen, and an opponent may gain control of a creature you control of his or her choice. That opponent retains control of that creature as long as Infernal Denizen remains in play. {T}: Gain control of target creature as long as Infernal Denizen remains in play.1
Illus. Drew Tucker
You must sacrifice the Swamps if you can. You cannot choose not to pay if you have them. [Aahz 1995/06/22]
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. [D'Angelo 1995/08/02]
Note - This card was creature type "Infernal-Denizen" until Oracle 2007/10/01, when it became "Demon".
