March of the Machines
Turning your own mana base into a war zone is the conceit here, and it cuts in every direction at once. Animating every noncreature artifact means your Sol Ring is a 1/1, your Mind Stone a 2/2, your Worn Powerstone a 3/3, and every one of them is suddenly a Doom Blade target, a Wrath of God casualty, and a creature that can be tapped, attack, and chump-block. The parenthetical clause is the design tell: Equipment animated into a creature can't equip, which means a board built on artifact augmentation collapses into a pile of vanilla bodies the moment this resolves. It reads like a tribute to an era when entire blocks ran on artifacts, but mechanically it is closer to a mass animation that hands an army to decks more artifact-dense than yours, or a combo enabler for builds packing zero-mana-value artifacts that animate into 0/0s and die on the spot, dragging artifact-matters triggers along with them. Rather than cast a removal spell, you weaponize a static rules change, and the asymmetry it creates depends entirely on who brought more artifacts to the table. That makes it a swingy, build-around enchantment rather than a clean answer: the same line of text that wrecks an opponent's artifact engine can vaporize your own, and living inside that gap between the two outcomes is what running it actually asks of you.
