Hit the Mother Lode + Mortuary + Skullwinder + Amulet of Vigor + Viscera Seer

Hit the Mother Lode

Mortuary

Skullwinder

Amulet of Vigor

Viscera Seer

How it works

1. Activate Viscera Seer by sacrificing Skullwinder.
2. When Skullwinder dies, Mortuary triggers, putting Skullwinder 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 Skullwinder from the top of your library and casting it without paying its mana cost, and creating seven tapped Treasure artifact tokens.
5. When Skullwinder and the Treasures enter the battlefield, Amulet of Vigor triggers seven times and Skullwinder triggers once.
6. Resolve all Amulet of Vigor triggers, untapping the Treasures.
7. Resolve the Skullwinder trigger, returning Hit the Mother Lode from your graveyard to your hand, and causing an opponent to return a card from their graveyard to their hand.
8. Activate seven Treasures by tapping and sacrificing them, adding 4.
9. Repeat.

This ingenious loop relies on a clever stacking mechanism where Mortuary ensures that whenever Viscera Seer sacrifices Skullwinder, the snake immediately returns to the top of your library. From there, casting Hit the Mother Lode allows you to discover directly into Skullwinder while generating a massive wave of tapped Treasures, whose entry is instantly smoothed over by Amulet of Vigor so you can immediately sacrifice them for the mana needed to repeat the entire cycle.
