Creeping Corrosion

Mass artifact destruction has always been one of green's foundational color-pie strengths, but it rarely arrived this clean. Earlier green answers tended to hang conditions on the wipe or shunt the heavy lifting onto other colors (red's Shatterstorm, white's scaled-up Disenchant variants), while green's own tools leaned situational. This is the sweep stripped to its bare statement: four mana, double-pip, no rider about who controls the artifacts, no choice of which to spare, no cap on the count. The flatness is the design. It takes every artifact on the board to zero, your own mana rocks and equipment included, and that symmetry is what files it into a green creature strategy that runs no artifacts of its own and wants an opposing affinity engine or equipment toolbox erased in a single card. The one seam worth naming is the verb: this destroys rather than exiles, so indestructible artifacts walk away untouched, the same loophole that lets a deck protect its key permanent against any "destroy all" effect. Inside that limit it is otherwise unconditional, with none of the creature-type clauses or converted-mana thresholds that hedged so many sideboard sweepers of its era. The card matters less as a single answer than as a line drawn in the color pie: green's hatred of artifacts gets a sanctioned, no-strings kill switch, and once that exists, any green deck can reach for it when the metagame tilts artifact-heavy.
