The exile cost is this engine's entire personality: it does not reanimate anything or return it to play, it grinds spent creature cards straight out of the graveyard into stats by the pound. Each card you feed it is gone for good, exiled rather than recycled, but you get back twice its count in raw power and toughness, so a graveyard clogged with used-up one-drops and dead chump blockers converts into a single oversized Zombie Horror at a two-for-one exchange rate. That trade rewards the deck that has already burned through its yard rather than one hoarding it for a single key reanimation target. The bodies it produces have no abilities, no evasion, and arrive tapped, which is the brake keeping the rate from being a finisher you drop in and swing with the same turn: you commit each Horror a full turn ahead of when it can attack. This is black's "graveyard as durable resource" school, the repeatable enchantment engines that ask you to maintain a body count rather than protect one creature. It never runs dry as long as the corpses hold out, so it is grindy by construction: an attrition payoff where the loser is whoever exhausts their pile of dead creatures first.
