Essence Harvest

Exile target creature. If you do, create a token that's of that creature, except it's 1/1, a Spirit in addition to its other types and has flying, then create a token that's a copy of the exiled creature, except it's a Zombie in addition to its other types, loses all activated abilities, and gains Devoid.
The Soulless Agents take orders from Necrosan, hunting down and absorbing the soul of any living creature their master orders them to, taking both soul and husk to him to do as he pleases.
