Death Rite Bird

Flying, wither
Whenever a creature dies with a -1/-1 counter,
exile it instead. Create a blue and black 1/1 Bird Skeleton token with flying and wither.
"In the time when there was no Erdtree, death was
burned in ghostflame. Deathbirds were the keepers of
that fire. The birds are graveyard fire keepers; it is
said they rake out the ashen remains of the dead from
their kilns."
