How it works
- At the beginning of your upkeep, Karn triggers.
- Holding priority, activate Lithoform Engine's first ability by paying 2 and tapping it, copying Karn's ability.
- Resolve the copy of Karn's ability, adding C for each artifact you control that cannot be spent to cast nonartifact spells.
- Activate Clock of Omens by tapping Staff of Domination and Grim Monolith, untapping Lithoform Engine.
- Activate Staff of Domination's first ability by paying 1, untapping it.
- Activate Grim Monolith's second ability by paying 4, untapping it.
- Repeat from step 2.
This intricate engine revolves around the upkeep trigger of Karn, Legacy Reforged, which rewards your artifact-heavy board with restrictive colorless mana that lingers through phases. By using Lithoform Engine to copy that very trigger, you rapidly amplify your mana production, while Grim Monolith helps fuel the activation costs and can be tapped alongside Staff of Domination to feed Clock of Omens. With Clock of Omens untapping your Lithoform Engine and Staff of Domination paying to untap itself, you establish a seamless loop that generates infinite mana, untaps, card draw, and life.
