Daretti, Scrap Savant

Few planeswalkers state their whole worldview in the plus ability: throw away your best artifacts on purpose, because the graveyard is just a staging area. The +2 looters away unwanted cards but quietly stocks artifacts you would rather have on the battlefield than in hand; the −2 then sacrifices an artifact you can spare to reanimate one you cannot, turning attrition into a profit loop. This is the engine that defines mono-red artifact reanimation as a strategy: a color that historically destroys its own permanents for value here gets a leader who recycles them indefinitely. The ultimate closes the loop into perpetuity, returning every artifact that dies at the next end step, which is why it wants a deck already built to feed it: pair the emblem with a dedicated sacrifice outlet or a stream of repeatable artifact deaths and each return refuels the next. What sets this design apart is that it asks for sacrifice in a color that already loves to sacrifice, then rewards the discipline with recursion red is normally denied. The legend-line permission to serve as commander is the load-bearing detail: built for a singleton format, it puts a reliable artifact-recursion engine in the command zone, available every game, which is how an effect this specific became the backbone of an archetype rather than a niche inclusion. Red rarely gets to play the long game with the graveyard. This is the card that hands it the keys.
