Ethercaste Knight
Exalted reads like an aggressive keyword, but it pays best on a defensive frame, and this is the cleanest illustration of that paradox. A 1/3 body that wants to swing alone seems contradictory until you watch the math: attacking solo turns it into a 2/4, large enough to trade up or push through while every other creature you control stays home to anchor the exalted stack. The 1/3 toughness is the point, not a compromise. It survives the early ground stalls that exalted decks deliberately build, then converts that survival into a single reliable attacker each turn. White and blue is a fitting home for the keyword's slow-attrition plan, since neither color wants a board-wide alpha strike; both would rather grind through one fattened threat while holding back interaction. As an artifact creature it also picks up a small second identity, slotting into the metal-matters and artifact-count subthemes that ran through its era of multicolor design. None of this makes it a centerpiece. It is the connective tissue of an exalted board: a body cheap enough to deploy early, sturdy enough to live, and happy to be the one creature that does the swinging while everything else just stands there making it bigger.
