Shepherd of the Cosmos + Viscera Seer + Changing Loyalty

Shepherd of the Cosmos

Viscera Seer

Changing Loyalty

How it works

1. Activate Viscera Seer by sacrificing Shepherd of the Cosmos.
2. When Shepherd of the Cosmos dies, Changing Loyalty triggers, returning Shepherd of the Cosmos from your graveyard to the battlefield.
3. When Shepherd of the Cosmos enters the battlefield, it triggers, returning Changing Loyalty from your graveyard to the battlefield attached to Shepherd of the Cosmos.
4. Resolve the Viscera Seer ability
5. Repeat.

This clever loop relies on a recursive exchange between the graveyard and the battlefield, entirely sustained by Viscera Seer's zero-cost sacrifice ability. When you sacrifice Shepherd of the Cosmos, Changing Loyalty triggers its ability to return the creature to the battlefield. In turn, Shepherd of the Cosmos enters the battlefield and its own triggered ability brings Changing Loyalty right back from the graveyard, attaching it securely to the Shepherd to ready the loop all over again.
