Hero of the Dunes + Fiend Hunter + Viscera Seer

Hero of the Dunes

Fiend Hunter

Viscera Seer

How it works

1. Activate Viscera Seer by sacrificing Fiend Hunter.
2. When Fiend Hunter dies, its second ability triggers, returning Hero of the Dunes to the battlefield from exile.
3. When Hero of the Dunes enters the battlefield, it triggers, returning Fiend Hunter from your graveyard to the battlefield.
4. When Fiend Hunter enters the battlefield, its first ability triggers, exiling Hero of the Dunes.
5. Resolve the Viscera Seer ability from step 1, causing you to scry 1.
6. Repeat.

This looping sacrifice engine is elegantly sustained by the passive interplay between your graveyard and the battlefield: Viscera Seer provides the free sacrifice outlet needed to repeatedly send creatures to the graveyard while letting you sculpt your draws with infinite scry 1 triggers. Meanwhile, Hero of the Dunes acts as the engine's beating heart, automatically pulling Fiend Hunter back from the graveyard to the battlefield whenever the Hero itself returns. As Fiend Hunter enters, its own triggered ability exiles Hero of the Dunes, which immediately sets up the next loop when Viscera Seer sends the Hunter back to the graveyard.
