Grimnir, Gallow's Dread

First strike, menace
Whenever another creature dies, another target
non-Cleric creature gains fear of Specters.
(Whenever a Specter enters the battlefield, return that creature to its owner's hand.)
{w/b}{w/b}, Exile a creature card from your graveyard:
Exile Grimnir, Gallow's Dread, then return it to
the battlefield under your control.
All our times have come...
