Knife and Death

If a thrown card ends up touching more than one creature or planeswalker you don’t control, Knife and Death will deal 1 damage to each of them. You’ll gain 1 life for each of them. Knife and Death won’t deal damage to creatures or planeswalkers you control that get hit, and you won’t gain life for them either.

Card sleeves are considered part of the card. If a thrown card (or its own card sleeve) is touching another card’s sleeve, it is considered touching that card.

No player may interfere with the throwing of the ten cards, including while they’re in flight.

Just a second is a variant of split second. Announcing Knife and Death instantly locks all permanents in place on the battlefield. As long as Knife and Death is on the stack, players can’t cast spells, activate abilities, or move their permanents.
