Witchcrafter Scroll — Ruling

Effetto 1

This card's effect that draws a card starts a Chain. (It does not target. It can be activated optionally at the end of the Damage Step when your Spellcaster monster destroys a monster by battle.)

This card's effect that allows you to send it to the Graveyard when activating the effect of a "Witchcrafter" monster instead of discarding does not start a Chain.

This card's effect that places it face-up in your Spell & Trap Zone from your Graveyard starts a Chain and activates in the Graveyard. (It does not target.)
This effect can be activated during your own End Phase if this card is present in your Graveyard and a "Witchcrafter" monster is face-up in your Monster Zone. (However, you cannot activate this effect during the turn you applied the effect of Witchcrafter Scroll that allows you to send it to the Graveyard when activating the effect of a "Witchcrafter" monster instead of discarding.)
When resolving this card's effect that places it face-up in your Spell & Trap Zone, even if you no longer have a "Witchcrafter" monster face-up in your Monster Zone, the effect is applied normally.
