Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If you control a face-down Defense Position monster, you can Special Summon this card (from your hand) in Defense Position. You can only Special Summon "Tindangle Base Gardna" once per turn this way. If a monster is Normal or Special Summoned while this monster is on the field, and that monster is now pointed to by an opponent's Link Monster (except during the Damage Step): You can Tribute this card; Special Summon 1 "Tindangle" monster from your hand or Deck in Attack Position or face-down Defense Position. * The above text is unofficial and describes the card's functionality in the OCG.
