Urza, Prince of Kroog

Two effects that rarely share a card in these colors sit stacked here: a static anthem for artifact creatures and a repeatable way to turn any artifact into a body. The lord line is the more familiar half, the kind of tribal buff white and blue occasionally hand to a mechanical-tribe deck, but the copy ability is the part doing the strategic work. Six generic mana clones an artifact you already control as a 1/1 Soldier that keeps its other types, which means the token benefits from the same +2/+2 anthem the moment it enters. The interesting wrinkle is what the copy retains: it is a 1/1 base, but it keeps every type and ability the original artifact had, so copying an artifact creature, a Vehicle, or an artifact with a static or activated ability duplicates that text alongside the fresh 3/3 body. The generic cost is the constraint that keeps it from spiraling too fast; six mana per activation asks you to build a board worth copying rather than lean on a single high-value target. Between the anthem propping up small artifact creatures and the ability manufacturing new ones out of whatever hardware is already on the table, the card wants a battlefield dense with artifacts, and it repays that density on both axes at once.
