Scuttling Sliver + Trazyn the Infinite + Grim Monolith + Imagecrafter

Scuttling Sliver

Trazyn the Infinite

Grim Monolith

Imagecrafter

How it works

1. Activate Imagecrafter by tapping it, causing Trazyn to become a Sliver until end of turn.
2. Activate Trazyn using Grim Monolith's ability by tapping it, adding CCC.
3. Activate Trazyn by paying 2, untapping it.
4. Repeat from step 2.

This ingenious engine turns your graveyard into a high-tech powerhouse by using Trazyn the Infinite's Prismatic Gallery ability to copy the activated mana-producing skill of a Grim Monolith resting safely in your graveyard. Because Grim Monolith's ability requires tapping to yield three colorless mana while its untap ability costs four, Trazyn alone falls short of going infinite—which is where the rest of the crew steps in. By leveraging Imagecrafter to temporarily rewrite Trazyn's creature type, you grant it the activated untap ability of Scuttling Sliver for just two mana, neatly bypassing the Monolith's steep untap cost. The result is a self-sustaining loop that pumps out infinite colorless mana and infinite untaps to fuel your victory.
