Necropolis Harvester

When Necropolis Harvester enters the battle-
field, you may sacrifice a creature. If you do,
each opponent sacrifices a creature. Repeat
this process for enchantment, artifact, and land.
Delirium — Necropolis Harvester has deathtouch,
lifelink, and vigilance as long as there are four or
more card types among cards in your graveyard.
"Here there lurks a ceaseless hunger, and for it rose
an eternal butcher."
