This clever loop hinges on combining Naru Meha, Master Wizard with the temporary resurrection magic of Pain 101 to create a self-sustaining cycle of reincarnation. When Naru Meha enters the battlefield, her ability copies Pain 101 to target herself, granting her an insurance policy that returns her to the battlefield whenever she dies. That is where Carrion Feeder steps in as the sacrifice outlet, letting you instantly bin Naru Meha to trigger her return while happily growing larger with an endless stream of +1/+1 counters. Because Naru Meha retains her flash and can be recast or instantly triggered right back into the fray, every repetition of this sequence pumps Carrion Feeder infinitely and floods the battlefield with endless death and enter-the-battlefield triggers.
