Psychic Overload

Lockdown auras live or die by how their controller can be made to break them, and this one prices the exit in a currency almost nobody is hoarding: artifact cards from hand, two at a time. Tapping the enchanted permanent on entry and keeping it tapped is the easy half; the wrinkle is that the escape clause is granted to the enchanted permanent's controller, not retained by you, so the prison comes with a key handed to the prisoner. That makes it a soft lock rather than a hard one, and the friction it generates scales with how artifact-light the opponent is. Born into the artifact-saturated environment that produced it, the discard cost reads as a deliberate counterweight: a set built around stockpiling artifacts gives the tapped player some hope of buying back, while a creature deck running few artifacts simply watches the threat sit. The structural cousin here is the family of "doesn't untap" effects descending from Icy Manipulator and the old "tap-down" auras, but where most of those are unconditional, this one negotiates: it leaves a door open and dares the opponent to pay an awkward price to walk through it. The result is a control piece whose value is entirely a function of the table's artifact density, which is also why it never escaped the parochial slot the set carved for it.
