As Accursed Marauder's enters-the-battlefield ability resolves, first the player whose turn it is chooses which creature they'll sacrifice, then each other player in turn order does the same. Players will know the choices of previous players when making their choice. Then all of the chosen creatures are sacrificed by their controllers simultaneously.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
