Chthonian Nightmare + Priest of Gix + Skittering Precursor + Goblin Bombardment

Chthonian Nightmare

Priest of Gix

Skittering Precursor

Goblin Bombardment

How it works

1. Activate Goblin Bombardment by sacrificing Priest of Gix.
2. When Priest of Gix dies, Skittering Precursor triggers, creating a 0/1 Eldrazi Spawn creature token.
3. Resolve the Goblin Bombardment ability, dealing 1 damage to any target.
4. Activate Chthonian Nightmare by paying EEE, sacrificing the Eldrazi Spawn and returning Chthonian Nightmare from the battlefield to your hand, returning Priest of Gix from your graveyard to the battlefield.
5. When Priest of Gix enters the battlefield, it triggers, adding .
6. Cast Chthonian Nightmare by paying 1.
7. When Chthonian Nightmare enters the battlefield, it triggers, causing you to get EEE.
8. Repeat.

This loop relies on an infinite resource cycle between your graveyard, battlefield, and hand, powered by Chthonian Nightmare's ability to recur creatures while bouncing itself back to safety. Priest of Gix acts as your primary engine fuel by generating three black mana upon entry, which is more than enough to pay for recasting Chthonian Nightmare. Meanwhile, Skittering Precursor quietly turns every sacrificed permanent into an Eldrazi Spawn token, supplying the exact sacrifice fodder and energy investment needed to fund Chthonian Nightmare's activation cost. Finally, Goblin Bombardment converts your endless cycle of dying creatures into an unstoppable stream of direct damage to any target, closing out the game entirely.
