Activate Ashnod's Altar by sacrificing Glasspool Mimic, adding CC.
When Glasspool Mimic dies, Enduring Renewal and Next of Kin trigger.
Resolve the Enduring Renewal trigger, returning Glasspool Mimic to your hand from your graveyard.
Resolve the Next of Kin trigger, putting Glasspool Mimic from your hand onto the battlefield as a copy of Boonweaver Giant.
When Glasspool Mimic enters the battlefield, it triggers, returning Next of Kin from your graveyard to the battlefield attached to Glasspool Mimic.
Repeat.
This intricate loop transforms a single clone into an unstoppable recursion engine, fueled by Ashnod's Altar providing a steady stream of colorless mana each time a creature is sacrificed. Enduring Renewal plays a vital passive role by replacing normal draws with a safety net that immediately returns any creature dying from the battlefield straight back to your hand. Meanwhile, Boonweaver Giant and Next of Kin work in tandem to fetch and reattach the crucial Aura, ensuring that Glasspool Mimic can continuously re-enter the battlefield as a fresh copy of the Giant to restart the cycle.
