Shadowcloak Vampire

The body is the headline here: a 4/3 that pays for its own evasion. Vampires have long been the tribe where a repeatable life payment doubles as a resource rather than a cost, and this is the workmanlike version of that idea: a beater that can shove four through a ground stall any turn it wants to, two life at a time, without ever needing an attached enchantment or an opponent's permission. The toughness of three is the quiet restraint: it climbs over blockers but still dies to most spot removal and the better combat tricks, so the evasion is a closing tool rather than a way to make the body unkillable. What makes the design hold together is that the cost is open-ended. There is no cap on activations, so a player flush on life can pay repeatedly across multiple turns, and an aggressive deck that has spent its own life total as a clock turns the ability into a finisher precisely when it can least afford the math. It is a creature built for the back half of a race, where four flying damage settles a board that has otherwise stopped moving.
