The strategy was to overload Mech tracking systems with a swarm of potential hideouts. The Shapers had made a strong early showing in the struggle for the Belt, and there were still isolated groups of Shaper agents moving from cell to cell behind Mech lines while the Ring Council was under siege. Many decoys were outfitted with propaganda broadcasting systems or with solar wind-tracking devices that could distort their orbits; some could shrink and expand repeatedly, disappearing from Mech radar. It was cheaper to manufacture them than it was to track down and destroy them, giving the Shapers a financial edge.
