This clever loop centers around Melira, Sylvok Outcast, whose passive ability prevents -1/-1 counters from ever being placed on your creatures, completely neutering the main drawback of persist. Because of this protection, when Rattleblaze Scarecrow dies and tries to return via its persist ability, it comes back entirely fresh with no counters at all. That endless recycling is supercharged by Reaper King, whose static lord effect pumps your Scarecrows while its triggered ability turns every single one of those recursive entries into a permanent destruction machine.
