6 rulings from Wizards of the Coast
- 22 September 2011You can name either half of a split card, but not both. If you do so, that half (and both halves, if the split card has fuse) can't be cast. The other half is unaffected.
- 22 September 2011The named card can be cast again once Nevermore leaves the battlefield.
- 22 September 2011Spells with the chosen name that somehow happen to already be on the stack when Nevermore enters are not affected by Nevermore's ability.
- 22 September 2011Although the named card can't be cast, it can still be put onto the battlefield by a spell or ability (if it's a permanent card).
- 22 September 2011No one can cast spells or activate abilities between the time a card is named and the time that Nevermore's ability starts to work.
- 19 March 2021If you name one of the faces of a modal double-faced card, players may still play the face you didn't name. (Players can never cast the back face of a transforming double-faced card)
