Boulderborn Dragon
A Dragon printed without a color: that is the design curiosity here, an artifact creature castable off any five mana without touching a single colored source. The colorless cost is the entire reason it exists, letting a deck of any color identity field a flying beater the manabase never fights over. The surveil-on-attack trigger is standard rate for an evasive body this size, a small filtering dividend that also stocks the graveyard for strategies that want it: not card advantage, since nothing is added to hand or board, but selection and setup at the cost of nothing beyond a swing. Vigilance is what makes that swing close to free, since the flyer keeps back on defense while still triggering surveil, so each combat filters a card without exposing the board. The ceiling is baked into the same simplicity, though: a 3/3 for five commands no respect on rate, and the appeal is entirely in the color-independence and the recurring, low-stakes card smoothing. A functional, unfussy piece built to hand artifact-leaning and multicolor shells a Dragon they can always afford to cast.
