The Citizen's Harvester

When The Citizen's Harvester enters the battlefield, put six -1/-1 counters on it and create
three 1/1 citizens that are every color.
{t}{1}{b} Sacrifice a non-token creature: remove a
-1/-1 counter from The Citizen's harvester and
create a 2/2 black zombie creature token.
Unlike most farmers, some just like to eat people
instead of vegetables.
