If this card is in your Graveyard: You can banish 1 "Duston" monster from your Graveyard; Special Summon this card in Defense Position as a Normal Monster (Fiend-Type/DARK/Level 1/ATK 0/DEF 1000) to your opponent's field. (This card is NOT treated as a Trap Card.) This effect can only be used once while this card is in the Graveyard. If Summoned this way, it cannot be Tributed, or be used as Material for a Fusion, Synchro, or Xyz Summon.
