Foundations Deck: Keen Engineering

Led by Sai, Master Thopterist, Keen Engineering leans into Blue's artifact and card-advantage strengths — building toward a board of small, efficient creations that add up over time rather than racing to an early finish. One of five mono-colored Commander decks in the Foundations line, designed specifically to teach the format's fundamentals without the complexity of a multicolor manabase.

The other four Foundations decks: Calling All Angels, Wretched Ranks, Reign of Dragons, Tramplesaurus Rex.
