Skittering Precursor

Sacrifice decks run on the same tension: the fodder that fuels a payoff has to come from somewhere, and every free body you spend digging for it costs a card. This inverts that math by paying you back in the currency it consumes. Wreck a nontoken permanent to any sacrifice outlet and an Eldrazi Spawn arrives, a 0/1 that converts itself into a single colorless mana. That ritual clause is what separates the loop from an ordinary value engine: each token cashes out once, so a chain of sacrifices ends with a pile of colorless floating rather than a wide board. The tokens are, pointedly, tokens, so feeding them back in never re-triggers the ability that made them; the ceiling is set entirely by how many real permanents you're willing to spend. Devoid does its work only on the drone, holding the 3/3 off the color pie so it registers as a colorless creature in an Eldrazi shell rather than a red one. The tokens produce because the triggered ability spells that out, not because of any keyword they inherit from their maker. Menace turns the same body into a 3/3 clock that can attack while the engine hums beneath it. What it rewards is the aristocrats archetype's oldest instinct, throwing your own stuff away, by refusing to let the throwing dead-end in an empty hand and board.
