Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Target Spells/Traps your opponent controls, up to the number of "Witchcrafter" monsters you control; return those targeted cards to the hand. During your End Phase, if you control a "Witchcrafter" monster, while this card is in your GY: You can add this card to your hand. You can only use 1 "Witchcrafter Draping" effect per turn, and only once that turn.
