Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
(This card's original Level is always treated as 12.) Cannot be Synchro Summoned. Must be Special Summoned (from your Extra Deck) by sending 2 Level 5 or higher monsters you control with the same Level to the GY (1 Tuner and 1 non-Tuner). Once per turn, when a Spell/Trap(s) is Set on your field (except during the Damage Step): You can Special Summon 1 "Power Tool" Synchro Monster or 1 Level 7 or 8 Dragon Synchro Monster from your Extra Deck. While you control another Synchro Monster, monsters cannot target this card for attacks, also neither player can target it with card effects.
