Quachil Uttaus

Whenever Quachil Uttaus deals damage to a
creature, exile that creature.
Whenever Quachil Uttaus deals combat damage
to a player, that player gets a dust counter. Then
if that player has three or more dust counters,
that player loses the game.
It was a figure no larger than a young child, but sere
and shriveled as some millennial mummy.
