Puresteel Paladin

The card that taught a generation what "free equip" actually means. Equipment had always carried a tax: every recast of an Equipment onto a new creature cost mana, which is what kept the archetype slow and fair. This Knight removes that tax once you hit three artifacts, turning equip costs to zero and letting you shuffle a single sword across an entire board, or onto whatever just dodged removal, at no cost. The draw clause is the engine that makes the build self-sustaining: each Equipment that resolves replaces itself, so a deck full of cheap or free artifact equipment stops being a sequence of card-disadvantage plays and becomes a cantrip chain. The two halves reinforce each other. The draws fuel more Equipment, the Equipment counts toward Metalcraft, and Metalcraft unlocks the zero-cost reattachment that lets one piece of gear do the work of several. The body is the deliberate weak point: a 2/2 that dies to almost anything, which keeps the package honest by forcing you to actually protect the linchpin rather than coasting on it. What it represents is a thesis statement for Equipment-matters decks, the card that proved the tribe could be an engine and not just a value-grind, and the reason "living weapon" and zero-equip designs keep getting measured against the standard it set.
