Liliana, Dreadhorde General
Legendary Planeswalker — Liliana
Whenever a creature you control dies, draw a card.
+1 : Create a 2/2 black Zombie creature token.
−4 : Each player sacrifices two creatures of their choice.
−9 : Each opponent chooses a permanent they control of each permanent type and sacrifices the rest.
As Liliana's second loyalty ability resolves, first the player whose turn it is chooses two creatures they control, then each other player in turn order does the same, knowing the choices made before them. Then all the chosen creatures are sacrificed at the same time. If any player can choose only one creature, that player does so.
