Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
[ Pendulum Effect ] You can target 1 Fiend monster you control; it gains 500 ATK (until the end of this turn) for each "Dark Contract" Spell/Trap with different names currently on your field or in your GY, then destroy this card. You can only use this effect of "D/D Gryphon" once per turn. ---------------------------------------- [ Monster Effect ] If you control a "D/D" monster: You can Special Summon this card from your hand in Defense Position. If this card is Pendulum Summoned: You can discard 1 "D/D" or "Dark Contract" card; draw 1 card. If this card is Special Summoned from the GY: You can add 1 "D/D" card from your Deck to your hand, except "D/D Gryphon". You can only use each effect of "D/D Gryphon" once per turn.
