Primitive Justice
A scaling artifact-destruction spell that solves the format-fragility problem most Disenchant effects suffer: the base mode strips a single artifact, but the additional-cost clause lets you keep buying targets, and the green payments stitch a life back onto each kill. The design choice that makes it interesting is putting the repeatability in the cost rather than the rate. You declare how many artifacts you want gone when you cast it, paying a toll for each, which means the card flexes from a spot answer to a board-clearing sweeper against artifact-heavy decks without ever being a dead card when only one target is worth hitting. Splitting the additional payments between and
encodes a small choice into the math: both tolls cost the same two mana, but the red payment is a plain kill while the green payment refunds a life per artifact, so a caster with access to both colors decides not just how many to destroy but which payment to use for each. It is an early experiment in giving a single removal spell a built-in mana sink, and the structure (a flat effect with an open-ended additional cost that adds targets) is the same skeleton later scalable artifact answers would reach for when they wanted repeatability without modality.
