Skente, Goddess of Malice

Unleash
At the beginning of your end step, if an opponent
lost 3 or more life this turn, put a worship counter

{1}{b}{r},{t}: Target opponent sacrifices X creatures
where X is the number of worship counters on
this card. If they can't Skente deals X damage to
them and up to one target planeswalker they
