Chainer, Dementia Master + Su-Chi + Chromatic Orrery + Angelic Chorus + Blasting Station

Chainer, Dementia Master

Su-Chi

Chromatic Orrery

Angelic Chorus

Blasting Station

How it works

1. Activate Blasting Station by tapping and sacrificing Su-Chi.
2. When Su-Chi dies, it triggers, adding CCCC.
3. Resolve the Blasting Station ability, dealing 1 damage to any target.
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 relies on sacrificing Su-Chi to Blasting Station, which triggers Su-Chi's death ability to generate four colorless mana. With Chromatic Orrery on the board allowing you to spend that mana as any color, you easily fund Chainer, Dementia Master's ability to recur Su-Chi straight from the graveyard. Because Chainer turns the returned creature into a Nightmare, Angelic Chorus also triggers upon entry to replenish your life total, neatly offsetting the life cost paid to Chainer.
