Hymn to the Dark Mother

All Zombies, Skeletons, Spirits, Undead, and
Vampires get +1/+1 and gain Vigilance.
Whenever a creature you control dies, exile it and create a 1/1 Black Skeleton creature token with "Regenerate: {b}" and you may pay {w/b}, if you do,
you may also create a 1/1 White and Black Spirit creature token with Flying.
Blood and Bone, Body and Soul, Heart and Spirit.
Listen to the Call of the Mother. Can you hear it?
