Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If this card is Normal Summoned, its original ATK becomes 1000. (Quick Effect): You can Tribute 1 DARK monster; reveal 3 Normal Traps from your Deck, your opponent randomly chooses 1 for you to Set on your field, and you shuffle the rest back into your Deck. You can only use this effect of "Lilith, Lady of Lament" once per turn.
