This looping engine transforms the raw materials of **Vishgraz, the Doomhive** into an unstoppable tide of mana and metal. When Vishgraz enters the battlefield, the static doubling power of **Primal Vigor** turns its normal mite creation into six Phyrexian Mite tokens instead of three, leaving you with a surplus of small artifacts. You can then feed Vishgraz directly to **Phyrexian Altar** for mana, triggering **Enduring Renewal** to immediately rescue Vishgraz from your graveyard and bounce it right back to your hand. Meanwhile, sacrificing just a few of your extra Phyrexian Mites provides the remaining mana needed to replay your commander, creating a self-sustaining loop that generates infinite mana, deaths, and tokens.
