Boonweaver Giant + Carrion Feeder + Gift of Immortality

Boonweaver Giant

Carrion Feeder

Gift of Immortality

How it works

1. Activate Carrion Feeder by sacrificing Boonweaver Giant
2. When Boonweaver Giant dies, Gift of Immortality triggers, returning Boonweaver Giant from your graveyard to the battlefield
3. When Boonweaver Giant enters, it triggers, returning Gift of Immortality from your graveyard to the battlefield attached to Boonweaver Giant.
4. Resolve the Carrion Feeder ability from step 1.
5. Repeat.

This elegant loop relies on a clever recursion engine built around Boonweaver Giant's entrance ability, which pulls Gift of Immortality straight from your graveyard to wrap itself back around the Giant every time it arrives. When you feed the Giant to Carrion Feeder's sacrifice ability, Gift of Immortality's trigger catches the dying Giant and immediately returns it to the battlefield to restart the cycle. The Carrion Feeder acts as both the ignition switch and the ultimate beneficiary, growing infinitely large on the back of this endless loop of sacrifices, deaths, and entries.
