Grim Shadow

Flying
When Grim Shadow enters the battlefield search
for a card in each graveyard. Put one card
selected in this way in your hand, put the rest on
the top of your library in any order.
{b}{p/b}: Exile target creature card from a players
graveyard. Create a 1/3 black Wraith Knight
token.
When the Shadow looms, the dead shall rise.
