This clever loop relies on transforming your creature graveyard into a relentless land-finding engine, made possible because Wight of the Reliquary naturally shares the Shaman creature type that allows Thornbite Staff to automatically equip to it upon entry. By sacrificing a creature to fuel Wight of the Reliquary's tutoring ability, the death triggers Thornbite Staff to instantly untap the Wight, readying it to be tapped again. Meanwhile, every land pulled from your library triggers Thranduil the Strategist's landfall ability to spawn a fresh 1/1 green Elf creature token, which immediately replaces the sacrifice fodder needed to keep the cycle spinning.
