Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
"Dark Magician" + "Red-Eyes Black Dragon" or 1 Dragon Effect Monster Cannot be destroyed by card effects. Neither player can target this card with card effects. During your Main Phase: You can destroy 1 monster your opponent controls, and if you do, inflict damage to your opponent equal to that monster's original ATK. You can use this effect a number of times per turn up to the number of Normal Monsters used as Fusion Material for this card. Once per turn, when a card or effect is activated (Quick Effect): You can discard 1 card; negate the activation, and if you do, destroy that card, and if you do that, this card gains 1000 ATK.
