Stasis Cocoon

The cheap, permanent leash for an artifact you would rather neutralize than destroy. Disenchant blows the artifact up and answers everything it does; this leaves it on the battlefield switched off, which earns its keep when the artifact's problem was what it could do rather than what it merely is. The shutdown within its lane is total: no attacking, no blocking, and crucially no activated abilities at all. Because the oracle text omits the usual mana-ability exception, even a rock that taps for mana goes dark, which makes this a tighter answer than auras that pacify combat alone. An Equipment you cannot remove cleanly stays pacified turn after turn; an artifact creature with a punishing tap or sacrifice ability sits as a dead body that can neither swing, block, nor pay its cost. What it pointedly cannot reach is triggered abilities or static effects, so an artifact whose menace is a passive bonus walks straight through it. That gap is the whole reason destruction often wins the argument: removing a permanent answers everything, while a leash answers only the parts gated behind activation or combat. As a piece of color-pie history it belongs to a moment when white was handed cheap, targeted, permanent-based artifact hate as a recurring tool rather than a single splashy answer, a lineage running from the early Disenchant variants toward the more surgical aura-style hosers that followed.
