Soul Stalker

Menace
When Soulstalker deals damage to a player, exile target card in that player's graveyard. If that card was a creature card, put a +1/+1 counter on Soul Stalker.
A scavenger in the underworld that preyed upon stray souls, it finds itself let loose upon a dead world with no gods to shepherd the spirits of the dead. Never did it dream of such a feast.
