Activate Blasting Station by tapping and sacrificing Su-Chi.
When Su-Chi dies, it triggers, adding CCCC.
Resolve the Blasting Station ability, dealing 1 damage to any target.
Activate Chainer by paying 3 and 3 life, returning Su-Chi to the battlefield from your graveyard.
When Su-Chi enters the battlefield, Verdant Sun's Avatar triggers, causing you to gain life equal to Su-Chi's toughness.
Repeat.
This clever loop turns the mechanical quirks of Chainer, Dementia Master and Su-Chi into an endless engine of destruction and vitality. By using Blasting Station to sacrifice Su-Chi, you trigger its death ability to generate four colorless mana, which is easily filtered and harnessed through the mana-fixing lens of Chromatic Orrery. Chainer then reaches into the graveyard to resurrect Su-Chi for three black mana and three life, turning it into a black Nightmare. Every time Su-Chi re-enters the battlefield, Verdant Sun's Avatar catches the entrance and swells your life total by Su-Chi's toughness, while Blasting Station untaps itself to feed the robot back into the sacrifice loop for infinite damage.
