Flying, double strike, lifelink, haste.
Scarlet Aeonia — When this creature transforms
into Malenia, Goddess of Rot, each opponent
gets a rot counter. Then put a -1/-1 counter on
each creature your opponents control for each
rot counter its controller has.
When Malenia, Goddess of Rot deals combat
damage to a player, proliferate.
"Let your flesh be consumed. By the scarlet rot."
