Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Once per turn, during the Standby Phase: You can pay 500 LP; send the top card of your Deck to the Graveyard, and if you do, this card gains ATK and DEF equal to that monster's Level x 200 if it was a monster. If this card in your possession is destroyed by your opponent's card (by battle or card effect) and sent to your Graveyard: You can add 1 monster with the lowest Level from your Graveyard to your hand (your choice, if tied).
