Malenia, Goddess of Rot

Flying, lifelink, deathtouch

Afflicted by Rot: At the beginning of your upkeep, each player sacrifices a creature. If they can’t, they lose life equal to the number of creatures they sacrificed this turn.

Whenever Malenia deals combat damage to a player, put three +1/+1 counters on her and proliferate.

If Malenia would leave the battlefield, return her to her initial form with three Scarlet Rot counters.
