Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Cannot be Normal Summoned/Set. Must first be Special Summoned (from your hand) by banishing 1 Level 8 or lower Thunder monster from your hand or face-up field, during the turn a Thunder monster's effect was activated in the hand. Once per opponent's turn (Quick Effect): You can banish 2 cards from your GY, including a Thunder monster, then target 1 Thunder monster you control; your opponent cannot target it with card effects this turn. Once per turn, during your End Phase: You can send 1 "Thunder Dragon" card from your Deck to the GY.
