Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Declare 1 card name; excavate the top card of your Deck, and if it is the declared card, add it to your hand, then you can add to your hand, or Special Summon, 1 DIVINE monster from your Deck. Otherwise, send it to the GY. You can only activate 1 "The True Name" per turn.
