Hit the Mother Lode + Mortuary + Eternal Witness + Amulet of Vigor + Viscera Seer

Hit the Mother Lode

Mortuary

Eternal Witness

Amulet of Vigor

Viscera Seer

How it works

1. Activate Viscera Seer by sacrificing Eternal Witness.
2. When Eternal Witness dies, Mortuary triggers, putting Eternal Witness on top of your library from your graveyard.
3. Resolve the Viscera Seer ability, causing you to scry 1.
4. Cast Hit the Mother Lode by paying 4, exiling Eternal Witness from the top of your library and casting it without paying its mana cost, and creating seven tapped Treasure artifact tokens.
5. When Eternal Witness and the Treasures enter the battlefield, Amulet of Vigor triggers seven times and Eternal Witness triggers once.
6. Resolve all Amulet of Vigor triggers, untapping the Treasures.
7. Resolve the Eternal Witness trigger, returning Hit the Mother Lode from your graveyard to your hand.
8. Activate seven Treasures by tapping and sacrificing them, adding 4.
9. Repeat.

This loop transforms Hit the Mother Lode into an infinite engine by leveraging Mortuary to seamlessly feed the top of your library with Eternal Witness after you sacrifice her to Viscera Seer. Because Hit the Mother Lode's massive mana value easily allows you to discover into Eternal Witness, you can cast the sorcery over and over while generating a surplus of Treasure tokens. Thanks to Amulet of Vigor, those Treasures instantly enter untapped, providing all the red and generic mana you need to repeat the entire process indefinitely.
