5 rulings from Wizards of the Coast
- 16 April 2021If Dream Strix becomes the target of a spell, it will be sacrificed before that spell tries to resolve. If it is the only target of that spell, it will be removed from the stack rather than resolving, and no part of its instructions will be performed.
- 16 April 2021If instructed to learn, you may do nothing. Discarding a card and putting a Lesson card into your hand are both optional.
- 16 April 2021If you bring a card into the game from outside the game in a Sealed Deck or Booster Draft event, you may select only a card that is in the card pool that you built your deck from.
- 16 April 2021If a card is brought into the game from outside the game, it will stay in the game until it ends or until its owner leaves the game, whichever comes first.
- 16 April 2021If you bring a card into the game from outside the game in a Constructed tournament (or a Constructed game played under tournament conditions), you may select only a card from your sideboard. In casual Constructed games, the card comes from your collection.
