Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
2 "Appliancer" monsters This linked card cannot be targeted by your opponent's card effects, or their monsters' attacks. During damage calculation, if an "Appliancer" Link Monster you control co-linked to this card battles an opponent's monster: Your battling monster gains ATK equal to the number of monsters co-linked to this card x 1000, during that damage calculation only. Once per turn, if an "Appliancer" Link Monster(s) you control that is not co-linked to this card is destroyed by battle or card effect: You can draw 1 card.
