During each player's end phase they must either sacrifice a non-land permanent, discard a card
from their hand, or mill a card from their library.
At your end phase you may select one creature in a graveyard and place it under your control
it is a zombie in addition to its other types.
When a card is placed into the graveyard from anywhere you may create a 2/2 black zombie token
