Forsaken Miner + Weapons Manufacturing + Phyrexian Altar + March of the Machines + Encroaching Mycosynth

Forsaken Miner

Weapons Manufacturing

Phyrexian Altar

March of the Machines

Encroaching Mycosynth

How it works

1. Cast Forsaken Miner by paying .
2. When Forsaken Miner enters, Weapons Manufacturing triggers.
3. Holding priority, activate Phyrexian Altar by sacrificing Forsaken Miner, adding .
4. Resolve the Weapons Manufacturing trigger, creating a Munitions token.
5. The Munitions token enters and dies as a state-based action due to having 0 toughness, triggering its ability, targeting an opponent or a permanent an opponent controls.
6. When you commit that crime, Forsaken Miner triggers, causing you to pay to return it from your graveyard to the battlefield.
7. Repeat from step 2.
8. Resolve all Munitions abilities, dealing infinite damage to opponents and/or permanents opponents control.

This loop transforms a humble skeleton into a relentless, damage-dealing engine by turning every piece of your board into a synchronized machine. Encroaching Mycosynth and March of the Machines work in tandem to ensure that the Munitions token created by Weapons Manufacturing enters as a creature with zero toughness, instantly dying to trigger its own damage-dealing ability. Directing that damage at an opponent or their things counts as committing a crime, which conveniently satisfies Forsaken Miner's resurrection condition. You simply feed that same Forsaken Miner into Phyrexian Altar to generate the black mana needed to pay its crime trigger, looping the Miner back to the battlefield to restart the entire sequence and burn your foes to ashes.
