Keeper of the Shrine (SDKS-EN018) [Structure Deck: Seto Kaiba]

This card can be treated as 2 Tributes for the Tribute Summon of a Dragon-Type monster. While this card is in your hand or Graveyard, if a face-up Dragon-Type monster on the field, except "Keeper of the Shrine", is sent to the Graveyard by a card effect or because it was destroyed by battle: You can Special Summon this card, then, if that monster sent to the Graveyard is a Normal Monster, you can add 1 Dragon-Type Normal Monster from your Graveyard to your hand. You can only use this effect of "Keeper of the Shrine" once per turn.
