Unctus, Grand Metatect + Fatestitcher + Forensic Researcher

Unctus, Grand Metatect

Fatestitcher

Forensic Researcher

How it works

1. Activate Fatestitcher by tapping it, targeting Forensic Researcher.
2. Fatestitcher triggers, causing you to loot.
3. Resolve the Fatestitcher ability, untapping Forensic Researcher.
4. Activate Forensic Researcher by tapping it, targeting Fatestitcher.
5. Forensic Researcher triggers, causing you to loot.
6. Resolve the Forensic Researcher ability, untapping Fatestitcher.
7. Repeat.

This loop relies on a clever tap-and-untap exchange between Fatestitcher and Forensic Researcher, where each creature's activation untaps the other to keep the cycle going. Unctus, Grand Metatect ties the engine together by granting those taps a passive triggered ability, turning every single activation into an instance of looting that digs through your deck while filling your graveyard.
