Vilemuck Elemental

Vilemuck Elemental's power and toughness are
each equal to the number of Swamp.
Whenever Vilemuck Elemental deal combat
damage to a player, put a muck counter on
target land that player control. That land is a
Swamp in addition to its other types for as long
as it has a muck counter on it.
"In Aurm, even the muck is malevolent."
