Recursion in Boros has always been an odd fit: the color pair wants to press the board, not rebuy value, and its graveyard interaction tends to be limited and reactive. This dwarf resolves that tension by attaching the recursion to a body that wants to attack anyway. The enter trigger pulls a noncreature, nonland card back from your graveyard, but it does not put the card in your hand: you get a window to recast it that runs until the end of your next turn. That casting window is the whole design lever. It lets you rebuy a burn spell or a combat trick without committing the mana on the same turn, so the trigger banks a resource rather than forcing an immediate spend, and the first strike keeps the 3/2 attacking into the turn where you cash it in. The card that comes back has to be something already used, which ties the ability to a deck that spends its spells early and often, exactly the kind of tempo shell that pairs a cheap first-striker with a graveyard full of one-cost interaction. It is not a value engine in the black-and-green sense; it is a single loop of a spell you already got mileage from, structured so the second use lands at the moment of your choosing rather than the moment it enters.
