This clever loop turns the graveyard into an endless waiting room for your creature, leveraging Viscera Seer as the executioner to sacrifice the creature currently wearing Deathrender. The moment that sacrifice happens, Deathrender’s trigger allows you to instantly drop that same creature right back onto the battlefield, while Enduring Renewal ensures it bounces straight to your hand if it hits the graveyard from the battlefield—though with Deathrender in play, it intercepts that path to immediately slip the creature back onto the battlefield and reattach itself. Because Enduring Renewal prevents you from naturally drawing creature cards (revealing them to your graveyard instead), you aren't even relying on a traditional hand size; you're simply feeding Viscera Seer an endless cycle of sacrifice, scrying through your entire deck while generating infinite death and sacrifice triggers.
