The Master of Salt

At the beginning of each end step, if one or more permanents went to an opponent's graveyard or
exile this turn, you may tap an untapped land you control. If you do, create a Salt token.(It's an
artifact with "{t}, Sacrifice this artifact: Add {c}.")
Sacrifice a Salt: The Master of Salt gains
hexproof until end of turn. Tap it.
"The ceiling is salt, the floor is salt, the walls are salt,
and to an extent the air is salt. And you breathe that
in, and you constantly taste the salt."
