Zhurbak Ghor of Grixis

Whenever a spell or ability you control would cause an opponent's creature to die, you may return that creature to play under your control. If you do, that creature becomes a Skeleton creature in addition to its other types and gains Fading 2.
Necromancers tell stories of an incurable, dwelling high in the mountains of Grixis, whose blood flows alongside Vis through his veins. The wiser among them realize those veins carry no blood at all.
