Abyssal Harvester (FDN 381)

Creature — Demon Warlock • Mana cost: {1}{B}{B} • Foundations • Rare

{T}: Exile target creature card from a graveyard that was put there this turn. Create a token that's a copy of it, except it's a Nightmare in addition to its other types. Then exile all other Nightmare tokens you control.

Final moments stricken by terror make the corpses into potent magical fuel.
