Notes & Rules Information
When Merchant of Venom's second ability resolves, first the player whose turn it is chooses which creature they're going to sacrifice, then each other player in turn order does the same. Players will know the choices of previous players when making their choices. Then all chosen creatures are sacrificed by their controllers simultaneously.
