Official Ruling
If an effect returns a copy of a spell to its owner’s hand, the copy ceases to exist.

Official Ruling
If instructed to learn, you may do nothing. Discarding a card and putting a Lesson card into your hand are both optional.

Official Ruling
If 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.

Official Ruling
If 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.

Official Ruling
If 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.

Divide by Zero was banned in standard on January 25, 2022. We're choosing to ban Divide by Zero to make blue control decks less effective against other mid-speed and slow decks and force them to be more intentional about which threats they choose to prepare for.
