SCP-O49, Plague's Harbinger

Deathtouch

Whenever SCP-049 destroys a creature, return it to the battlefield under your control as a black Zombie in addition to its other types.

Whenever a non-Zombie creature an opponent controls dies, its controller mills two cards.

Look at target opponent’s hand. Exile a creature card from their graveyard. You may cast that creature this turn using any type of mana.
