Savia, Death Cult Matron

When Savia comes into play, return target
creature from your graveyard to play. It is a black
and it is a Zombie in addition to its creature types.
Whenever a creature you control dies, return it to
the battlefield at the end of turn. It is a black and it
is a Zombie in addition to its creature types.
When Savia leaves the battlefield, sacrifice all
Zombies you control.
