Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If your opponent draws a card(s): Increase this card's Level by the number drawn. While this card's Level is higher than its original Level, it gains ATK equal to the difference x 500. When your opponent activates a Spell Card or effect, while you control "Shining Sarcophagus" (Quick Effect): You can negate the activation, and if you do, increase this card's Level by 1. You can only use this effect of "Silent Magician Zero" once per turn.
