Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
During the Main Phase (Quick Effect): You can activate this effect; immediately after this effect resolves, Tribute Summon 1 Fairy monster face-up. If this card is sent to the GY: You can make all monsters your opponent currently controls lose 500 ATK/DEF for each Fairy monster on the field, until the end of this turn. You can only use each effect of "Capricious Darklord" once per turn. * The above text is unofficial and describes the card's functionality in the OCG.
