Malenia, Blade of Miquella

First Strike, Lifelink
When Malenia deals damage to a player, that
player gets 1 Scarlet Rot counter. When Malenia
deals damage to a player with a Scarlet Rot
counter, double the amount of Scarlet Rot
counters they have. At the beginning of their
upkeep, each player loses 3 life for each
Scarlet Rot counter they have.
You will witness true horror.
