Felothar the Steadfast

Most combat is a power-versus-toughness negotiation: attackers are priced by the number that hits, defenders by the number that survives. This flips the axis. Combat damage from your side reads off toughness instead of power, which makes the fat, sturdy, traditionally passive bodies (walls, high-toughness ramp creatures, the 0/5 sitting behind them) into legitimate threats, and the second line quietly grants them permission to attack despite defender. The two abilities are built to feed each other: a defensive wall is now an offensive engine, and a board of high-toughness creatures suddenly wants to be swinging every turn. The sacrifice outlet closes the loop by rewarding the same stat distribution, drawing off toughness and discarding off power, so a 0/5 nets five cards and no discard while a bear costs you as much as it gives back. That asymmetry is the design's spine: it isn't a generic sacrifice-for-value button, it's a filter that pays out proportionally to how lopsided your creatures already are toward toughness. The whole package points one direction, toward a deck of durable, low-power, high-toughness bodies that would be inert under normal combat math and are instead attacking, blocking, and cashing themselves in for cards. It's a rare case of a commander redefining what "creature stats" are worth rather than just amplifying the usual ones.
