Reveillark + Body Double + Viscera Seer

Reveillark

Body Double

Viscera Seer

How it works

1. Activate Viscera Seer by sacrificing Body Double.
2. When Body Double leaves the battlefield, it triggers its Reveillark ability, returning itself from your graveyard to the battlefield as a copy of Reveillark.
3. Resolve the Viscera Seer ability.
4. Repeat.

This elegant loop relies on Body Double entering the graveyard as a copy of Reveillark, thanks to its clever static replacement effect. Once set up, you simply sacrifice Body Double to Viscera Seer to trigger Reveillark's leaves-the-battlefield ability, which fishes Body Double right back out of the graveyard to do it all over again. Because Body Double re-enters as a copy of Reveillark every time, this self-sustaining cycle generates infinite sacrifices, entry triggers, and endless scry depth.
