8 rulings from Wizards of the Coast
- 24 September 2021If you copy a permanent spell cast this way (perhaps with a card like Double Major), the copy becomes a token that's a copy of the card's back face, even though it isn't itself a double-faced card.
- 24 September 2021The second ability of Dennick, Pious Apprentice affects only spells and abilities that actually target cards in graveyards. Spells and abilities that affect cards in graveyards without targeting them may still affect them, move them to other zones, and so on.
- 24 September 2021"Disturb [cost]" means "You may cast this card transformed from your graveyard by paying [cost] rather than its mana cost."
- 24 September 2021A spell cast this way enters the battlefield with its back face up.
- 24 September 2021When you cast a spell using a card's disturb ability, the card is put onto the stack with its back face up. The resulting spell has all the characteristics of that face.
- 24 September 2021The back face of each card with disturb has an ability that instructs its controller to exile if it would be put into a graveyard from anywhere. This includes going to the graveyard from the stack, so if the spell is countered after you cast it using the disturb ability, it will be put into exile.
- 24 September 2021Disturb is found only on the front faces of some double-faced cards.
- 24 September 2021To determine the total cost of a spell, start with the mana cost or alternative cost (such as a disturb cost) you're paying, add any cost increases, then apply any cost reductions. The mana value of a spell cast using disturb is determined by the mana cost on the front face of the card, no matter what the total cost to cast the spell was. (This is a special rule that applies only to nonmodal double faced-cards, including ones with disturb.)
