Catacomb Sifter

Three mana buys a body, a token, and a scry engine that ticks whenever another creature you control dies: the value math here is denser than the rate suggests. The Eldrazi Scion is the connective tissue. It enters alongside the Sifter, which means the death clause is already primed the moment you crack the Scion for colorless mana, and that single point of ramp doubles as fodder for any sacrifice loop you build around it. The scry-on-death trigger is the quiet workhorse. It cares about quantity of deaths, not quality, so it converts a board of cheap, expendable creatures into card selection without asking you to spend any extra resource beyond the deaths that were happening anyway. Aristocrats shells want exactly this shape: a sacrifice payoff that smooths draws while the killing happens elsewhere. What keeps the engine from spiraling is that the scry only filters and never draws, so the advantage accrues one card at a time rather than snowballing. Devoid strips the color off a creature still cast on Golgari mana, so it reads as a colorless body wearing black and green clothing, a wrinkle that matters mostly for effects that check color rather than for how it plays. As a card that ramps, spawns fodder, and rewards a death-heavy board in one slot, it sits in the design space where a token generator and a sacrifice engine quietly become the same card.
