Shepherd of the Cosmos + Kaya's Ghostform + Viscera Seer

Shepherd of the Cosmos

Kaya's Ghostform

Viscera Seer

How it works

1. Activate Viscera Seer by sacrificing Shepherd of the Cosmos.
2. When Shepherd of the Cosmos dies, Kaya's Ghostform triggers, returning Shepherd of the Cosmos from your graveyard to the battlefield.
3. When Shepherd of the Cosmos enters the battlefield, it triggers, returning Kaya's Ghostform from your graveyard to the battlefield attached to Shepherd of the Cosmos.
4. Resolve the Viscera Seer ability, causing you to scry 1.
5. Repeat.

This clever loop relies on a self-sustaining cycle of sacrifice and resurrection. You sacrifice Shepherd of the Cosmos to Viscera Seer, which immediately triggers Kaya's Ghostform to bring the Shepherd right back to the battlefield. Because the Shepherd's own entrance ability targets a permanent with mana value 2 or less, it plucks Kaya's Ghostform straight out of the graveyard and reattaches it, ready to do it all over again.
