You Cannot Hide from Me
Most persistent schemes want to grind, sticking around to bleed value across a whole game. This one is built to expire. Its combat trigger is a targeted evasion package: +2/+2, vigilance, and unblockable, applied to whichever attacker most needs to connect. That reads like a repeatable payoff, but the end-step check is the leash. Once any opponent has been knocked below half their starting life, the scheme abandons itself when their turn ends, ejecting from your face-up rotation the moment it has done the aggressive work it was built to do. The trigger only helps you close, and closing is exactly what retires it: the card asks you to pick a target you can actually push through for a chunk of damage, not to farm incremental value across a long game. That self-limiting shape also sidesteps a familiar attrition problem, where opponents dismantle your board while your face-up cards sit inert. Here, a single creature becomes a guaranteed hit every combat, which is how a lopsided multiplayer game gets short. It belongs to the ongoing-scheme category but behaves less like a persistent engine and more like a countdown: useful precisely until it accomplishes its stated goal, then gone from the rotation for good.
