Trip Noose

Tapping a creature was once a complete answer to it. Before vigilance was widespread and instant-speed reach filled every color, an attacker or blocker held down at the right moment swung a combat math problem decisively, and a repeatable tapper did that every turn for a flat two-mana activation. This is the colorless, anyone-can-run version of that effect: an Icy Manipulator restricted to creatures, stripped of the land and artifact reach but cheap to deploy and color-agnostic in a way no Master Decoy could be. The two-mana-plus-tap activation sets the ceiling on its abuse: it pins a fresh creature each turn but never two, and because it is a noncreature artifact it can fire the turn it enters as long as you hold the open. The honest read is that it sits a tier below the premium tappers because tapping is a tempo tool, not a removal one: the creature comes back next untap, and against a board that outnumbers you a single tap does not stop the bleeding. Where it earns its slot is in a duel of attrition: it neutralizes one oversized threat indefinitely, or pins down a key blocker to push damage through, the grinding utility a colorless artifact lends any deck willing to carry it.
