Boonweaver Giant + Next of Kin + Enduring Renewal + Glasspool Mimic // Glasspool Shore + Phyrexian Altar

Boonweaver Giant

Next of Kin

Enduring Renewal

Glasspool Mimic // Glasspool Shore

Phyrexian Altar

How it works

1. Activate Phyrexian Altar by sacrificing Glasspool Mimic, adding one mana of any color.
2. When Glasspool Mimic dies, Enduring Renewal and Next of Kin trigger.
3. Resolve the Enduring Renewal trigger, returning Glasspool Mimic to your hand from your graveyard.
4. Resolve the Next of Kin trigger, putting Glasspool Mimic from your hand onto the battlefield as a copy of Boonweaver Giant.
5. When Glasspool Mimic enters the battlefield, it triggers, returning Next of Kin from your graveyard to the battlefield attached to Glasspool Mimic.
6. Repeat.

This intricate loop is masterminded by Boonweaver Giant and a Glasspool Mimic copying it, working in tandem with Phyrexian Altar to churn out infinite sacrifice triggers and colored mana. The engine is glued together by Enduring Renewal, which replaces the usual trip to the graveyard by immediately bouncing the sacrificed creature straight back to your hand. Meanwhile, Next of Kin ensures that every time your cloned giant hits the dirt, you can instantly cheat it right back onto the battlefield from your hand, seamlessly keeping the cycle spinning endlessly.
