Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
When you activate this card: You can take 1 Level 4 or lower "Myutant" monster from your Deck, and either add it to your hand or Special Summon it. If a Level 8 or higher "Myutant" monster(s) you control would be destroyed by card effect, you can banish this card you control instead. You can only activate 1 "Myutant Expansion" per turn.
