Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
When this card declares an attack: Special Summon 1 "Mecha Phantom Beast Token" (Machine-Type/WIND/Level 3/ATK 0/DEF 0). This card's Level is increased by the total Levels of all "Mecha Phantom Beast Tokens" you control. While you control a Token, this card cannot be destroyed by battle or card effects. Once per turn, during either player's turn: You can Tribute 1 Token, then target 1 monster your opponent controls; change that target to face-up Defense Position.
