Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If this card is Special Summoned: You can add 1 "Change" Quick-Play Spell Card from your Deck to your hand. If this card is sent to the GY: You can add 1 "HERO" monster from your Deck to your hand, except "Elemental HERO Shadow Mist". You can only use 1 "Elemental HERO Shadow Mist" effect per turn, and only once that turn.
