Extort was designed as a tax that compounds: a per-spell drain that costs nothing on the board and everything in patience, and stapling it to a two-drop with lifelink is where the keyword finds its most efficient home. The body is forgettable. A 2/1 trades up rarely and dies to almost anything thrown at it. The value lives entirely in what happens after it resolves, when every subsequent spell becomes a payment that swings two life across the table at once, doubled whenever the creature actually connects. The extort trigger is the real engine, asking only that you keep choosing to pay. The hybrid mana on that trigger matters less for the deck it goes in (it costs to cast, so it always wants both colors) than for how loosely it taxes you afterward: any spare mana of either color funds the next point of drain, so a cantrip-heavy hand that would otherwise gain nothing starts leaking life out of every opponent, turn after turn. That is the trick. A card that rewards a long game without needing the long game to be good for you any other way. Left unanswered, a single one of these closes out a board stall that no creature on the table can break, one at a time. It is the cleanest distillation of extort as a mechanic: small, cheap, and relentlessly incremental.
