Chainer, Dementia Master + Su-Chi + Chromatic Orrery + Trostani, Selesnya's Voice + Phyrexian Altar

Chainer, Dementia Master

Su-Chi

Chromatic Orrery

Trostani, Selesnya's Voice

Phyrexian Altar

How it works

1. Activate Phyrexian Altar by sacrificing Su-Chi, adding one mana of any color.
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, Trostani triggers, causing you to gain life equal to Su-Chi's toughness.
5. Repeat.

This intricate loop centers around Chainer, Dementia Master, who bends the rules of the graveyard by letting you repeatedly resurrect Su-Chi by paying life and black mana. Every time you feed Su-Chi to Phyrexian Altar, its death trigger floods your pool with colorless mana, while the Altar itself provides the colored mana needed to fuel Chainer's activation cost. Chromatic Orrery ensures all that colorless energy flows freely without color restriction, while Trostani, Selesnya's Voice passively rewards you for every single resurrection by turning Su-Chi's toughness into a stream of endless life.
