Boonweaver Giant + Ashnod's Altar + Kaya's Ghostform

Boonweaver Giant

Ashnod's Altar

Kaya's Ghostform

How it works

1. Activate Ashnod's Altar by sacrificing Boonweaver Giant
2. When Boonweaver Giant dies, Kaya's Ghostform triggers, returning Boonweaver Giant from your graveyard to the battlefield tapped.
3. When Boonweaver Giant enters, it triggers, returning Kaya's Ghostform from your graveyard to the battlefield attached to Boonweaver Giant.
4. Repeat.

This clever loop turns Ashnod's Altar into a continuous engine of life and rebirth by exploiting Boonweaver Giant's ability to fetch its own salvation. When you sacrifice the Giant to the Altar for a pair of colorless mana, Kaya's Ghostform immediately triggers upon its death to pull the creature right back from the graveyard. That fresh entry lets the Giant tutor up the very same Kaya's Ghostform from your graveyard and strap it back onto itself, resetting the entire cycle.
