Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
2+ Cyberse monsters When this card is Link Summoned: You can choose unused Main Monster Zones equal to the number of monsters currently in the Extra Monster Zones; those zones cannot be used while this monster is face-up on the field. You can only use this effect of "Excode Talker" once per turn. Monsters this card points to gain 500 ATK, also they cannot be destroyed by card effects.
