Mirror of Life Trapping

A stax piece disguised as a "gotcha" trap. The construction is deceptively cruel: it only exiles creatures that were cast, so tokens, reanimated bodies, blink returns, and anything that enters some other way slide past untouched, which quietly tells you what kind of deck to build around it. The real engine is the second clause. Every cast creature that gets caught displaces the last one, returning all previously trapped permanents to the battlefield under their owners' control, so the artifact never actually keeps anything permanently: it holds exactly the most recent victim hostage and hands the rest back the instant someone casts another creature. That makes it a soft lock rather than a hard one, a revolving door where the table can pop the prisoner loose by feeding it a fresh, worse target. The design leans on that tension deliberately, punishing tap-out creature decks that develop by casting one threat at a time while doing almost nothing to a token swarm or a graveyard build. Reading the "return all other permanent cards" line is where players get burned, because the phrasing invites you to imagine a growing pile of exiled creatures when the mechanic is engineered to release the pile every time it fires. It rewards the pilot who understands that the trap works best when nobody else can afford to trip it again.
