This clever loop transforms a single instance of damage into a devastating, self-sustaining chain reaction. It all hinges on With Great Power . . ., which redirects any incoming damage destined for you directly to your enchanted creature—in this case, Spiteful Sliver. Once the Sliver takes that redirected hit, its own native ability triggers alongside Repercussion, creating a feedback loop where the Sliver shoots a target player while Repercussion bounces the damage right back to the Sliver's own controller.
