Witchcrafter Marka

You can Tribute this card from your hand or field; add 1 "Witchcrafter" Field or Continuous Spell from your Deck to your hand. If a face-up "Witchcrafter" monster(s) you control leaves the field by an opponent's card effect, while this card is in your GY (except during the Damage Step): You can Special Summon this card (but banish it when it leaves the field), and if you do, Tribute 1 monster your opponent controls. You can only use each effect of "Witchcrafter Marka" once per turn.
