Rulings
As Dusk Mangler's triggered ability resolves, each opponent, starting with the next player in turn order, chooses a creature, knowing the choices made before them. All of those creatures are sacrificed at the same time. Next, each opponent chooses a card in their hand without revealing it, and all of those cards are discarded at the same time. Then, each opponent loses 4 life.
