Black Widow, Daring Operative

A self-mill payoff wearing an evasion package, and the two halves are wired together with more care than the numbers suggest. The enters trigger buries three of your own cards; the combat trigger cashes that graveyard out as a life-loss burst scaled to the creature cards you have stacked there. Note what it does not do: it drains opponents without gaining you a point, so this is a pure clock, not a life swing. The menace on a 3/4 body is the connective tissue. That profile pokes through a stalled board and forces a two-blocker tax at exactly the moment the reward for connecting is a hit that grows every turn the game runs long. Where most graveyard payoffs ask you to sacrifice creatures or loop them, this one only asks that they arrive in the yard and stay there, so the count climbs passively as the game wears on. That reframes the deckbuilding question from "how do I recur my dead creatures" to "how do I stack my own graveyard high with them while still landing a hit." The mill on entry is a down payment toward that count rather than a play against anyone else's library: your own cards feeding your own damage output. It is a payoff that rewards a graveyard you were filling anyway, bolted onto a creature built to make the trigger hard to stop.
