Extricator of Sin // Extricator of Flesh

The 0/3 front half is glue, not a threat: it enters, eats a permanent you have already wrung dry, and converts a spent artifact or a dying blocker into an Eldrazi Horror token. That entry sacrifice is the same motion an aristocrat shell performs constantly, which is what makes the transform clause the clever half of the design. Delirium turns bookkeeping you were already doing into a free upkeep upgrade with no second cast required: hit the type threshold your yard fills toward anyway, and the Cleric flips on its own timer. Extricator of Flesh comes back as a repeatable outlet, feeding any non-Eldrazi creature into the same colorless mold for two mana and a tap, and it hands those Horrors vigilance so the swarm it manufactures attacks and holds the ground in one motion. What ties the two faces is that both spend permanents for bodies: the front is a one-shot conversion on entry, the back is a spigot that keeps running. And the back half has outgrown the condition that produced it, no longer caring about the graveyard state it cleared to arrive; it has graduated into a self-sufficient engine. A sacrifice payoff and a sacrifice outlet folded into a single three-drop, with the flip as the seam between the one-shot and the loop.
