Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
You can discard this card; add to your hand, 1 of your "Thunder Dragon" cards that is banished or in your GY, except "Thunder Dragonroar". If this card is banished, or sent from the field to the GY: You can Special Summon 1 "Thunder Dragon" monster from your Deck in Defense Position, but return it to the hand during the End Phase. You can only use 1 "Thunder Dragonroar" effect per turn, and only once that turn.
