Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
The first time each "Witchcrafter" monster you control would be destroyed each turn, by battle or card effect, it is not destroyed. You can only use 1 of the following effects of "Witchcrafter Bystreet" per turn, and only once that turn. ● If a "Witchcrafter" monster you control would discard to activate an effect, you can send this card from your field to the GY instead. ● During your End Phase, if you control a "Witchcrafter" monster, while this card is in your GY: You can place this card face-up in your Spell & Trap Zone.
