Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
2 Level 3 monsters Once per turn, during your opponent's turn: You can detach 1 Xyz Material from this card; Special Summon 1 "Phantom Token" (Fiend-Type/DARK/Level 1/ATK 500/DEF 500). (This is a Quick Effect.) While you control a "Phantom Token", your opponent cannot target this card for attacks. This card gains 500 ATK for each "Phantom Token" you control.
