How it works

1. Activate Ashnod's Altar by sacrificing Clone, adding CC.
2. When Clone dies, Enduring Renewal and Next of Kin trigger.
3. Resolve the Enduring Renewal trigger, returning Clone to your hand from your graveyard.
4. Resolve the Next of Kin trigger, putting Clone from your hand onto the battlefield as a copy of Boonweaver Giant.
5. When Clone enters the battlefield, it triggers, returning Next of Kin from your graveyard to the battlefield attached to Clone.
6. Repeat.
