Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
2 Cyberse monsters Once per turn, if another Link Monster is Link Summoned: This card cannot be destroyed by battle or card effects for the rest of this turn. If a Link Monster, that was Link Summoned using this card as material, is destroyed by an opponent's card effect, while this card is in the GY (except during the Damage Step): You can Special Summon this card. You can only use this effect of "Restoration Point Guard" once per turn.
