Golgari Necroharvester

Trample, haste
When Golgari Necroharvester enters the
battlefield, put the top five cards of your library
into your graveyard. You may put a land card
from your graveyard onto the battlefield.
Golgari Necroharvester's power and toughness
are each equal to the number of creature cards
in your graveyard.
