Dwarven Vigilantes
An attacker that converts a clean swing into a removal spell: when it gets through unblocked, you can redirect its damage to a creature instead of the player. The design is a small lesson in opportunity cost. The trade is built right into the trigger, since redirecting the damage means the creature assigns none in combat, so you choose each turn between a face hit and a 2-point shot at something across the board. That makes blocking against it a genuine puzzle: leave it unblocked and it might pick off a tapped-out blocker or a small threat; throw a body in front and you have neutralized the redirect for free. The ceiling is modest because the damage scales off power, and the body sits at 2/2, so the "removal" half clears only the cheapest creatures. It belongs to an old strand of red design that paid creatures off for connecting rather than for raw stats, the same impulse that later produced unblocked-trigger payoffs of every stripe. As a piece of combat-math design it holds up better than its rate suggests; the friction is honest, the choice is recurring, and nothing about it is hidden in fine print.
