Nohl, Eternal Ferrymaster

Whenever a creature leaves a graveyard, instead
put it to the battlefield under your control. It is
a black and white zombie in addition to it's other
types.
As long as your devotion to White and Black is
less than 8, Guardian of the Endless River is not
a creature.
If your devotion to White and Black is at least 8,
zombies you control can not be blocked.
