Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Level 6 or higher monsters your opponent controls cannot target this card for attacks. You can only use each of the following effects of "Destiny HERO - Decider" once per Duel. ● If this card is Normal or Special Summoned: You can add 1 "HERO" monster from your GY to your hand during the End Phase of this turn. ● When a card or effect is activated that would inflict damage to you, while this card is in your GY (Quick Effect): Return this card to your hand, and if you do, make that effect damage to you 0.
