Paradox Engine + Lithoform Engine + Gilded Lotus

Paradox Engine

Lithoform Engine

Gilded Lotus

How it works

1. Cast the spell, triggering Paradox Engine.
2. Tap Gilded Lotus for 3.
3. Pay 2 and tap Lithoform Engine to copy the Paradox Engine trigger.
4. Resolve the copied Paradox Engine trigger.
5. Repeat from step 2 for infinite mana and nonland permanent untaps.

This intricate machinery relies on Paradox Engine to weaponize the simple act of spellcasting, turning every future action into a wave of untaps across your board. Gilded Lotus serves as the primary battery, tapping for three mana to comfortably fuel Lithoform Engine's first ability. By spending that mana to have Lithoform Engine copy the Paradox Engine trigger, you stack multiple untaps from a single cast. This loop continuously refreshes Gilded Lotus and Lithoform Engine, resulting in infinite colored mana and an endlessly untapping board of nonland permanents.
