Chainer, Dementia Master + Su-Chi + Chromatic Orrery + Verdant Sun's Avatar + Ashnod's Altar

Chainer, Dementia Master

Su-Chi

Chromatic Orrery

Verdant Sun's Avatar

Ashnod's Altar

How it works

1. Activate Ashnod's Altar by sacrificing Su-Chi, adding CC.
2. When Su-Chi dies, it triggers, adding CCCC.
3. Activate Chainer by paying 3 and 3 life, returning Su-Chi to the battlefield from your graveyard.
4. When Su-Chi enters the battlefield, Verdant Sun's Avatar triggers, causing you to gain life equal to Su-Chi's toughness.
5. Repeat.

This clever loop exploits Su-Chi's death trigger alongside Ashnod's Altar to generate a net surplus of mana each cycle, feeding Chainer, Dementia Master's reanimation ability while keeping you comfortably afloat with life gained from Verdant Sun's Avatar. Chromatic Orrery quietly ties the whole engine together by letting you spend that massive pool of colorless mana as any color, fueling Chainer's black-mana-heavy activation cost over and over again. As a delightful bonus, Chainer's continuous static ability even pumps Su-Chi into a Nightmare, though its primary role here is acting as a repeatable graveyard-to-battlefield conduit for infinite sacrifices.
