Atka-mit, Shining Necropolis

Creatures in your graveyard have
Embalm {w/b}{w/b}{u/b}{u/b}
Zombies you control get +1/+1
Atka-mit enters the battlefield tapped with five
rest counters on it.
As long as Atka-mit has a rest counter on it,
it's a land. (It's not a creature.)
Whenever you cast a spell from your graveyard,
you may remove a rest counter from Atka-mit.
