Quicksilver Amulet

The cheat that asks for patience instead of mana. Every fatty in your hand is normally gated twice: once by its own cost, once by the sorcery-speed window where you can deploy it. This artifact tears down both gates and replaces them with a single ongoing tax. Any creature, however expensive, however carefully a control opponent has sequenced their counterspells, drops onto the battlefield for a flat activation at instant speed. That instant-speed clause is the whole point. You hold up the activation through their turn, let them tap out or commit to the stack, and slam the threat in their end step, where it dodges sorcery-speed removal and never exists as a spell to counter. The friction Wizards built in is real: the body never triggers its own cast effects (it is put onto the battlefield, not cast), the activation stacks four mana on top of the four to cast the Amulet itself, so the full sequence stays mana-hungry even when assembled in one turn, and a single artifact-destruction spell sets the whole thing back to square one. It is the design ancestor of a long line of ramp-adjacent and reanimator-adjacent cheat effects, the artifact that proved instant-speed haymaker deployment could be sold as a repeatable engine you tap each turn. It has stayed relevant for a simple reason: the bodies it cheats out keep getting bigger while its tax never moves.
