Dirge of the Forsaken Plane

At the beginning of each player's end step, that
player loses 3 life unless they sacrifice a creature
Betrayal — If a spell or ability caused that player controls caused them to lose life, discard cards, or sacrifice permanents this turn, instead that player sacrifices any number of creatures, then loses 3
life for each creature they control.
The anguished cry of a tormented plane is a sound
none forget.
