Mortuary + Ashnod's Altar + Vivien, Monsters' Advocate

Mortuary

Ashnod's Altar

Vivien, Monsters' Advocate

How it works

1. Activate Ashnod's Altar by sacrificing the nontoken creature, adding CC.
2. When the creature dies, Mortuary triggers, putting the creature from your graveyard onto the top of your library.
3. Cast the creature by paying its mana cost.
4. Repeat.

This elegant loop turns a simple recycling engine into an unstoppable cascade of value by leveraging Ashnod's Altar to turn your creatures into raw colorless mana. As each sacrificed creature heads to the graveyard, Mortuary immediately intercepts it, placing the card right back on top of your library. This is where Vivien, Monsters' Advocate comes in to complete the puzzle: her static ability lets you look at the top card of your library at any time and cast creatures directly from it, allowing you to replay your sacrificed creature using the mana generated by the Altar.
