Medusa, Gorgon Queen

Deathtouch
Whenever Medusa deals combat damage to a
player, they get a Stone Gaze counter. If a player
has three or more Stone Gaze counters, they
lose the game.
In Medusa's gaze lies the silent peril of stone—a chilling embodiment of beauty turned deadly,
where a single look can transform life's vigor into the cold permanence of stone.
