Kor Line-Slinger

A repeatable tapper strapped to a body with zero power: it never trades, never blocks for value, and earns its keep only by pointing its activation at whatever it can hold down turn after turn. The power-3-or-less clause on the target is the real boundary. It can leash a stream of small attackers indefinitely, but the genuine threats, the fatties and finishers, walk right past it. Call it a friction generator rather than a control piece: a way to slow a board of weenies without ever spending a card. The tap doubles as a tempo tool on offense, peeling a small blocker off the board before an alpha strike. The fragility is in the chassis, not the stack: kill the Scout in response to its activation and the ability still resolves, the target still taps, because destroying the source of an activated ability does not remove that ability from the stack. What an opponent gains by trading removal for a 0/1 is the loss of every future tap, not the one already in flight. So the real bound on the design is the body itself, a creature that almost anything kills and that a single attacker over the power threshold simply ignores. Cheap recurring control on a frame that earns its mana while the curve is low and becomes dead weight the moment the board climbs above three.
