Malenia, Blade of Miquella

Vigilance, Rotted 1 (Players dealt combat damage by this card also gain 1 rot counter.)

Scarlet Aeonia - Once per turn, if this creature would be dealt lethal combat damage, instead give
the attacking player one rot counter.

Aeonia Bloom - If this creature dies, give all opponents two rot counters.

If all opponents have at least three rot counters, you may transform Malenia, Blade of Miquella.
