text: As Smallpox resolves, first each player loses 1 life at the same time. Next, each player chooses a card in hand without revealing it, then all of the cards are discarded at the same time. Then starting with the player whose turn it is and proceeding in turn order, each player chooses a creature, knowing the choices made before them. All of the creatures are sacrificed at the same time, then finally repeat this process for lands.
