Ravenous Skirge
A printed 1/1 that hits for 3 in the air: the attack trigger front-loads the math so the body on the page misrepresents what it actually pressures. The +2/+0 comes free every time it turns sideways, with no mana, no sacrifice, and nothing to target, which puts it among the pure tempo flyers whose whole value is repeated chip damage opponents have to respect at 3, not 1. The toughness staying at 1 is what holds the rate in check: it dies to any incidental ping, folds in a trade against another flier, and makes a miserable blocker, so the back half of its body is essentially decoration. This is lean evasive black aggression of an early era, the kind built to nibble points from above while heavier pieces minded the ground. There is no value held in reserve for a patient player here; the creature pays out only when it connects, and contributes nothing while parked on defense. A low-investment threat that rewards swinging and punishes sitting still, with all of its upside spent in the attack step.
