Grand Necromancer

Rekindle {b}{g} (When this card is put into your graveyard from your library, you may cast it for its rekindle cost.)
Whenever a creature card is put into your graveyard from your library, you may pay its casting cost. If you do, return it to the battlefield tapped. If it's a creature, it's a
Zombie in addition to its other creature types.
The corruption oozes madness, eating away at your sanity until you find yourself a part of it.
