Scuttling Sliver + Trazyn the Infinite + Amorphous Axe + Coveted Jewel

Scuttling Sliver

Trazyn the Infinite

Amorphous Axe

Coveted Jewel

How it works

1. Activate Trazyn using Coveted Jewel's ability by tapping it, adding three mana of any color.
2. Activate Trazyn by paying 2, untapping it.
3. Repeat.

This ingenious mana-generating loop relies on Trazyn the Infinite's *Prismatic Gallery* ability to absorb the activated traits of artifacts sitting in your graveyard. By utilizing Amorphous Axe to make Trazyn every creature type, it becomes a valid target for Scuttling Sliver's static ability, which grants it the crucial "{2}: Untap this creature" activation. Once Trazyn has soaked up Coveted Jewel's mana-producing skill from the graveyard, you can tap it for three mana and pay two of that mana to untap it with Scuttling Sliver's granted ability, netting infinite colored mana in the process.
