Nimblewright Schematic

Two mana buys a token twice: once when the artifact enters, and again when it dies from the battlefield. That doubled trigger is the design hook, because it points you toward destroying your own permanent rather than protecting it. Every trip through a graveyard from play spits out a fresh 1/1 Construct, and the Construct is itself a body a sacrifice outlet can consume, which makes the whole package a self-replenishing fuel line: sacrifice the artifact, get a Construct, sacrifice the Construct, and if you can loop the artifact back onto the battlefield, do it all again. That puts it squarely in aristocrat and treasure-token strategies, where a permanent whose death is worth more than its presence is exactly the shape you want. It belongs to a small class of artifacts built to be consumable, where the correct play is often to kill your own permanent on purpose. Both halves of the trigger reward the same behavior: treat the artifact as ammunition, not as a fixture. And the payout is source-agnostic. It comes whether the destruction is your own sacrifice engine cashing it in or an opponent's removal spell walking into a free 1/1, which turns what would otherwise be a downside of removal into a minor upside.
