The Millennium Scale

When The Millennium Scale enters, you may sacrifice a permanent. If you do, each opponent sacrifices a permanent they control that shares a card type with it. Each opponent who can't discards a card.

Whenever an opponent draws a card, if it's not the first card they drew this turn, they may pay {1}. If they don't, they lose 2 life.

Whenever a creature attacks you, it's controller may pay {1}. If they don't, they lose 1 life.
