Embalming Chamber

{3}, Sacrifice a Swamp: Exile target creature card
that was put into your graveyard from play this
turn and put 3 time counters on it. If it doesn't
have suspend, it gains suspend.
A creature exiled by Embalming Chamber enters
play with a Mummy counter. Creatures with a
Mummy counter have a base toughness of 1 and
"If this creature leaves play, exile it instead."
Each creature with a Mummy counter is a black
Mummy instead of its normal color and type.
