Urza's Workshop

The Urza's land cycle has always been a puzzle of parts: Mine, Power-Plant, and Tower each tap for colorless alone, but assembled they scale into a mana engine well above their individual worth. This one takes that assembly logic and reroutes it through metalcraft, so the payoff is no longer about gathering the specific triplet but about running an artifact-dense board. The unconditional first ability keeps it a clean colorless source when the board has no metalcraft to lean on, but the second mode rewards two separate axes at once: how many Urza's lands you control and whether you have three or more artifacts on the battlefield. That double dependency is what makes it a genuine build-around rather than a strict upgrade to the classic tron pieces. It wants the density of an artifact deck and the redundancy of multiple Urza's-typed lands, and it pays proportionally when you deliver both. The design nods to the original tron dream while quietly changing the required inputs, which means it can slot into artifact-centric shells that would never assemble the traditional three-piece set. It is less a fourth tron land than a translation of the tron idea into the metalcraft framework: same explosive-mana fantasy, different membership test.
