Chainer, Dementia Master + Su-Chi + Chromatic Orrery + Trostani, Selesnya's Voice + Goblin Bombardment

Chainer, Dementia Master

Su-Chi

Chromatic Orrery

Trostani, Selesnya's Voice

Goblin Bombardment

How it works

1. Activate Goblin Bombardment by sacrificing Su-Chi.
2. When Su-Chi dies, it triggers, adding CCCC.
3. Resolve the Goblin Bombardment 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, Trostani triggers, causing you to gain life equal to Su-Chi's toughness.
6. Repeat.

This loop is a masterclass in recycling a single artifact through the graveyard, fueled entirely by the life-generating safety net of Trostani, Selesnya's Voice to offset the heavy costs demanded by Chainer, Dementia Master. When you sacrifice Su-Chi to Goblin Bombardment, its death trigger conveniently provides more than enough colorless mana to cover Chainer's reanimation fee, while Chromatic Orrery ensures that raw colorless energy gets filtered into the exact black mana needed to keep the engine running. Every single time Su-Chi cycles back to the battlefield, Chainer's static type-granting ability ensures it enters as a Nightmare to pump its stats, which simultaneously triggers Trostani to keep your life total safely out of reach from Chainer's life-payment tax.
