Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
FLIP: You can add 1 "Subterror" card from your Deck to your hand, except "Subterror Guru". You can target 1 other face-up monster on the field; change both that monster and this card to face-down Defense Position. This is a Quick Effect if you control another "Subterror" card. You can only use each effect of "Subterror Guru" once per turn. * The above text is unofficial and describes the card's functionality in the OCG.
