Beckoner, Betrayer of Death

Menace, trample, haste
Escape — {b}{r}, Exile eight other cards from
your graveyard. (You may cast this card from your graveyard for its escape cost.)
When Beckoner enters the battlefield, if you
cast it for its escape cost, you lose life equal to
the total mana value of cards exiled by it.
"On the backs of the damned, he rose."
