Anticognition

Text:

Counter target creature or planeswalker spell unless its controller pays . If an opponent has eight or more cards in their graveyard, instead counter that spell, then scry 2.

Rulings:

• 9/25/2020 If an opponent has eight or more cards in their graveyard, Anticognition can still target only a creature or planeswalker spell.
• 9/25/2020 Anticognition will counter the spell and let you scry 2 if any opponent has eight or more cards in their graveyard, not just that spell’s controller.
• 9/25/2020 Anticognition can target a spell that can’t be countered. You’ll still scry 2 if an opponent has eight or more cards in their graveyard.
• 9/25/2020 An ability that offers a bonus if an opponent has eight or more cards in their graveyard won’t provide additional benefits if more than one opponent has eight or more cards in their graveyard. There are also no additional benefits no matter how many cards are in an opponent’s graveyard, as long as there are at least eight.
• 9/25/2020 In a multiplayer game, once an opponent leaves the game, they won’t be considered for such an effect, no matter how many cards they had in their graveyard before leaving the game.
