Fortress of the Dead

{t}: Add {b}. You lose 1 life unless you
control three or more Spirit creatures.
{1}{b}{b}, {t}: Exile target creature card from
your graveyard. Create a 1/1 black Spirit creature token. If a creature card with flying
was exiled, that token gains flying. The same
is true for deathtouh, haste, lifelink, and
menace.
