Activate Ashnod's Altar by sacrificing Salvager of Secrets, adding CC.
When Salvager of Secrets dies, Mortuary triggers, putting Salvager of Secrets on top of your library from your graveyard.
Cast Hit the Mother Lode by paying 4, exiling Salvager of Secrets from the top of your library and casting it without paying its mana cost, and creating five tapped Treasure artifact tokens.
When Salvager of Secrets and the Treasures enter the battlefield, Amulet of Vigor triggers five times and Salvager of Secrets triggers once.
Resolve all Amulet of Vigor triggers, untapping the Treasures.
Resolve the Salvager of Secrets trigger, returning Hit the Mother Lode from your graveyard to your hand.
Activate five Treasures by tapping and sacrificing them, adding 2.
Repeat.
This ingenious loop turns a massive sorcery into a self-sustaining engine by letting Ashnod's Altar sacrifice Salvager of Secrets to fund the casting of Hit the Mother Lode. Thanks to Mortuary, that sacrificed Salvager of Secrets goes right back to the top of your library where Hit the Mother Lode's discover mechanic can immediately find and cast it for free. Meanwhile, Amulet of Vigor ensures the five tapped Treasure tokens enter ready to be cracked for the exact mana needed to replay the sorcery, while Salvager of Secrets recycles Hit the Mother Lode from your graveyard back to your hand for the next iteration.
