Salvaging Station + Weapons Manufacturing + Clock of Omens + Atog

Salvaging Station

Weapons Manufacturing

Clock of Omens

Atog

How it works

1. Activate Salvaging Station by tapping it, returning the noncreature artifact with mana value 1 or less from your graveyard to the battlefield.
2. When the noncreature artifact enters the battlefield, Weapons Manufacturing triggers, creating a Munitions artifact token.
3. Activate Clock of Omens by tapping the noncreature artifact returned in step 1 and the Munitions token, untapping Salvaging Station.
4. Activate Atog by sacrificing the noncreature artifact.
5. Repeat.

This intricate engine relies on Salvaging Station as its beating heart, using its tap ability to continuously recur a cheap noncreature artifact from your graveyard to the battlefield. Each time that artifact returns, Weapons Manufacturing triggers to forge a Munitions token, which then serves as prime fuel alongside your recurred artifact to pay the activation cost of Clock of Omens and untap the Station. To keep the loop sustainable, Atog steps in as the sacrifice outlet, clearing away the recurrest artifact so Salvaging Station has a valid target waiting in the graveyard for the next iteration. Because the Munitions token leaves the battlefield during this sacrificial loop, its triggered ability fires repeatedly to incinerate any target while making Atog infinitely large.
