Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If your opponent controls a Level 5 or higher monster, you can Special Summon this card (from your hand). A Synchro Summon using this card as a Material cannot be negated. If a player Synchro Summons using this card as a Material, the other player cannot activate cards or effects when that monster is Synchro Summoned.
