Chainer, Dementia Master + Su-Chi + Mycosynth Lattice + Angelic Chorus + Altar of Dementia

Chainer, Dementia Master

Su-Chi

Mycosynth Lattice

Angelic Chorus

Altar of Dementia

How it works

1. Activate Altar of Dementia by sacrificing Su-Chi.
2. When Su-Chi dies, it triggers, adding CCCC.
3. Resolve the Altar of Dementia ability, causing target player to mill cards equal to Su-Chi's power.
4. Activate Chainer by paying 3 and 3 life, returning Su-Chi to the battlefield from your graveyard.
5. When Su-Chi enters the battlefield, Angelic Chorus triggers, causing you to gain life equal to Su-Chi's toughness.
6. Repeat.

This intricate loop hinges on Chainer, Dementia Master and Mycosynth Lattice working together to make every creature in your graveyard a black Nightmare, allowing Chainer to continually resurrect Su-Chi for three black mana and three life. Each time Su-Chi enters the battlefield, Angelic Chorus leverages its toughness to continuously pad your life total, mitigating Chainer's life-payment cost. Meanwhile, sacrificing Su-Chi to Altar of Dementia mills your opponents out while generating four colorless mana from Su-Chi's death trigger—more than enough to fuel the entire engine indefinitely.
