Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
2+ Effect Monsters Your opponent cannot target Link-4 or higher monsters you control with card effects, also they cannot be destroyed by battle. If you control a "Firewall" Link Monster (Quick Effect): You can banish Link Monsters from your GY whose combined Link Ratings equal exactly 3; Special Summon this card from your GY, but banish it when it leaves the field. You can only use this effect of "Protectcode Talker" once per turn.
