Urza's Blueprints

The math here is brutal and intentional. Pay six to play it, tap it once that same turn for a card (artifacts have no summoning sickness, so the draw is available immediately), then pay six again on your next upkeep just to keep the thing on the table. That second payment is the whole point. Echo on a card-advantage artifact is a design lever that splits the cost into two separate windows, so the card cannot quietly amortize into a value engine the way an uncosted draw rock would; you commit twelve mana across two turns before the second card ever resolves, and the rate stays honest only because the bill comes due twice. The flavor reinforces the bargain: Urza sketching the Legacy Weapon's components, a blueprint that demands a second round of funding before the project goes anywhere. It belongs to the broad family of Urza's-block artifacts that gestured at powerful effects through deliberately punishing costs, the counterweight to the same era's genuinely broken pieces. Where those cards defined a format, this one defined the floor: a reminder that "tap to draw a card" is only as strong as the total you paid to keep the engine running, and that echo was built specifically to make sure you paid full freight rather than sneaking value out of a single down payment.
