Songs of the Dead

Each player sacrifices a creature.
For each creature sacrificed this way, you create
a +1/+1 black Skeleton creature token with
Deathtouch.
You may cast "Songs of the Dead" from your graveyard if a creature died this turn, then
remove "Songs of the Dead" from the game.
"The songs of the dead echo through the darkness,
luring the living to their doom"
