Soul Foundry + Corridor Monitor + Gilded Lotus + Virtue of Knowledge // Vantress Visions

Soul Foundry

Corridor Monitor

Gilded Lotus

Virtue of Knowledge // Vantress Visions

How it works

1. Activate Gilded Lotus by tapping it, adding three mana of any color.
2. Activate Soul Foundry by paying 2 and tapping it, creating a token copy of Corridor Monitor.
3. When the Corridor Monitor token enters the battlefield, it triggers twice, untapping Soul Foundry and Gilded Lotus.
4. Repeat.

This ingenious engine relies on Soul Foundry to repeatedly deploy Corridor Monitor, turning the automaton's entry into a self-sustaining loop of mechanical rebirth. Thanks to Virtue of Knowledge bolstering the chamber, every single copy of the Monitor entering the battlefield triggers twice instead of once, providing all the untap power needed to refresh both the Foundry and Gilded Lotus. With the Lotus generating a surplus of mana on each iteration—providing three mana while the Foundry only asks for two to activate—you quickly amass infinite colored mana and an unbounded army of metal automatons.
