Chainer, Dementia Master + Su-Chi + Mycosynth Lattice + Trostani, Selesnya's Voice + Goblin Bombardment

Chainer, Dementia Master

Su-Chi

Mycosynth Lattice

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 intricate loop uses Goblin Bombardment to sacrifice Su-Chi for raw damage, which in turn triggers Su-Chi's death ability to generate four colorless mana. With Mycosynth Lattice turning everything colorless and smoothing your mana production, you can easily pay Chainer, Dementia Master's life and mana cost to resurrect Su-Chi right back to the battlefield. Meanwhile, Trostani, Selesnya's Voice happily rewards your endless creature recursion by padding your life total with every single entry, completely offsetting Chainer's life drain and sustaining the slaughter.
