Leveler + Out of the Tombs + Gate to the Afterlife + Ashnod's Altar

Leveler

Out of the Tombs

Gate to the Afterlife

Ashnod's Altar

How it works

1. Cast Leveler by paying 5.
2. Leveler enters the battlefield, exiling your library.
3. Activate Ashnod's Altar by sacrificing any creature, adding CC.
4. When the creature dies, Gate to the Afterlife triggers, causing you to return any creature from your graveyard to the battlefield due to Out of the Tombs, discard a card and gain 1 life.
5. Repeat from step 3.

This delightfully twisted engine relies on Leveler entering the battlefield to completely empty your library in a single stroke, setting the stage for Out of the Tombs to turn every subsequent draw into a direct-to-battlefield creature revival. With your library gone, sacrificing creatures to Ashnod's Altar not only generates an endless supply of colorless mana but also triggers Gate to the Afterlife with every death. Gate to the Afterlife keeps the loop greased by letting you draw and discard, seamlessly chaining into the creature return ability granted by Out of the Tombs to ensure you never run out of fodder for the Altar.
