Street Urchin

The Background frame exists to hand a partner-style identity to a commander that never asked for one, and this one turns whatever you named on the command zone into a Goblin Bombardment on legs. The grant is narrow in the way that matters: it attaches only to commander creatures you own, so the effect concentrates in the command zone rather than spreading across the board the way a wider anthem would. What it buys is a repeatable sacrifice outlet welded to a ping, and the two halves feed each other: your commander becomes both the outlet and the payoff for every death you can manufacture, converting spare tokens, expendable artifacts, and dying creatures into damage aimed at faces or small blockers. The mana cost per activation stops it from being a free machine gun, but the outlet itself is the prize; aristocrats decks want unconditional, cheap ways to throw bodies away, and this staples one onto a card already central to the deck's plan. It is a design that reads as a support piece and functions as an engine, the rare Background that changes how a deck wins rather than just what it is worth.
