Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Send 1 "Monarch" Spell/Trap Card from your hand to the Graveyard; draw 2 cards. You can banish this card from your Graveyard; reveal 3 "Monarch" Spell/Trap Cards from your Deck, your opponent chooses 1 for you to add to your hand, and you shuffle the rest back into your Deck. You can only use this effect of "Pantheism of the Monarchs" once per turn.
