Disruption Aura

Most aura-based removal answers a permanent once and stops there: it shrinks a creature, locks down its ability, taps it out of combat, and then the work is finished. This one never finishes. By stapling a recurring upkeep tax onto an artifact, it forces the controller to re-buy their own permanent every turn, paying its full mana cost or feeding it to the graveyard. Pin it on a cheap trinket and it barely registers; pin it on an expensive engine or a mana rock the opponent leans on, and you have doubled that artifact's cost in perpetuity, bleeding a chunk of their mana every turn they want to keep it. It is soft removal dressed as a tax, and the conditionality is the whole design tension: the artifact never dies on its own terms, so the pressure exists only as long as the controller can afford the toll, which makes the aura strongest precisely when their mana is already stretched. The trade-offs are real. Against a flush board it accomplishes nothing, and a single enchantment-removal spell unwinds the entire arrangement. It speaks to a blue impulse that prefers to make a permanent inconvenient rather than make it vanish, leaning on attrition over a clean kill: grinding, asymmetric pressure that rewards a deck already ahead in the resource race rather than one scrambling to climb back.
