- 16 April 2021If the back face of a modal double-faced card is countered, you will not be able to exile any cards, including the one that you countered, because those cards have only their front-face characteristics (including name) in the graveyard, hand, and library.
- 16 April 2021Countering a spell normally puts that card into the graveyard, so that card will be there to find and exile.
