Ulalek, Fused Atrocity + Lithoform Engine + Spawn-Gang Commander

Ulalek, Fused Atrocity

Lithoform Engine

Spawn-Gang Commander

How it works

1. Cast Spawn-Gang Commander by paying 3.
2. Ulalek and Spawn-Gang Commander trigger.
3. Holding priority, activate Lithoform Engine's first ability by paying 2 and tapping it, copying Ulalek's trigger.
4. Resolve the copy of Ulalek's trigger, causing you to pay CC to copy the Spawn-Gang Commander spell, Ulalek's trigger and Spawn-Gang Commander's trigger.
5. Resolve the copy of the Spawn-Gang Commander spell.
6. Resolve the copy of Spawn-Gang Commander's trigger, creating three 0/1 Eldrazi Spawn creature tokens.
7. Activate two Eldrazi Spawn creature tokens by sacrificing them, adding CC.
8. Resolve the copy of Ulalek's trigger from step 4, causing you to pay CC to copy the Spawn-Gang Commander spell, Ulalek's trigger and Spawn-Gang Commander's trigger.
9. Repeat from step 5.
10. Once you have infinite C and Eldrazi Spawn tokens, you may sacrifice them to Spawn-Gang Commander to deal infinite damage to any target(s).

This looping masterpiece turns a single Eldrazi cast into an unstoppable avalanche by leveraging Ulalek, Fused Atrocity and Lithoform Engine to endlessly copy both the spell and its cast triggers. When you cast Spawn-Gang Commander, its entry creates valuable Eldrazi Spawn tokens that can be sacrificed for colorless mana to pay for Ulalek's color-coding tax. By duplicating the cascade of triggers with Lithoform Engine and Ulalek, Fused Atrocity, you generate infinite mana and tokens, leaving you free to direct Spawn-Gang Commander's damage-dealing ability at any target for the win.
