Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
1 Level 4 Tuner + 1+ non-Tuner monsters Once per turn, if a card(s) leaves the Extra Deck (except during the Damage Step): You can make all monsters you currently control gain 500 ATK (permanently), then you can negate the effects of 1 face-up card on the field, until the end of this turn. During the End Phase, if this card is in the GY because it was sent there this turn: You can Special Summon 1 LIGHT Spellcaster monster from your hand or Deck whose ATK equals its own DEF. You can only use this effect of "Despian Luluwalilith" once per turn.
