This ingenious loop turns a harmless insect swarm into an infinite engine that forces a draw, utilizing a clever replacement effect to bypass the natural limits of your deck. You begin by casting Doomsday to carefully curate your graveyard and library with five specific Insect cards while stripping away everything else, creating a closed ecosystem. Then, you enchant yourself with Wheel of Sun and Moon, whose vital static ability ensures that any card headed to your graveyard—including the ones you mill—is instead redirected to the bottom of your library in a continuous loop. With that perpetual motion machine in place, you activate Grist, the Hunger Tide and use its +1 ability to start milling and creating Insect tokens. Because Grist's own ability triggers itself to repeat whenever an Insect is milled, and Wheel of Sun and Moon continuously recycles those milled Insects right back to the bottom of your deck, the mill-and-create process becomes an unstoppable, unending loop that forces the game to a draw.
