Reign of the Pit

The symmetry is the trap. A symmetrical edict that promises a payoff: each player sacrifices a creature, and you walk away with a flier sized to the carnage. The wrinkle is the phrase "of their choice." Every opponent picks their own sacrifice, which means they feed you their worst creature: a token, a mana dork, a one-power chump. The Demon's power scales off the total power of everything sacrificed, so the spell is only as large as your opponents are willing to make it, and they are never willing. You sacrifice too, which means in the worst case you trade your best body for a Demon barely bigger than the thing you gave up. This is a card built for a crowded board, where the math shifts: more players means more sacrifices means a bigger Demon, and the politics of whose creature dies smallest can shape how everyone responds. It also wants you to manufacture the inputs, pairing the edict with creatures you would not mind losing while every opponent parts with chaff of their own. The honest read is that the symmetrical edict is a liability dressed as an engine: the upside is real, but it is gated behind everyone cooperating with their own thinning, which rarely happens. The line that makes it sing is the one your opponents have no incentive to walk.
