Knight of Hanoi [Key Points] Crossout Designator is a card that can be activated by declaring the same name of a card or effect of your opponent, negating that opponents card or effect until the end of the turn, making it an incredibly powerful card, but it requires you to banish from the Deck, and by banishing them, you lose the chance to draw into them
