I'm skeptical that [[Wind Drake]] plus looting is good enough in a world of [[Kor Skyfisher]]s.
Tron could cast [[Ulamog's Crusher]] or some other giant creature and then cast and equip Brass Knuckles the next turn. Is that better than just casting another giant the next turn? Better enough to offset how sad you are when you draw the Knuckles without a creature?
Some kind of combo deck might be a more likely home for the Knuckles. I really liked this SaffronOlive deck from last year that used Brass Knuckles to combo with [[Metalwork Colossus]]. But that's a rare, and I can't think of anything in Pauper that could stand in for it.
Blood Aspirant seems like it has the best chance among these cards to find Pauper success. There have already been decks that combo kill with [[Disciple of the Vault]]. Maybe Aspirant plus [[Fling]] could provide some redundancy to that plan.
