Scuttling Sliver + Trazyn the Infinite + Imagecrafter + Prismatic Geoscope

Scuttling Sliver

Trazyn the Infinite

Imagecrafter

Prismatic Geoscope

How it works

1. Activate Imagecrafter by tapping it, causing Trazyn to become a Sliver until end of turn.
2. Activate Trazyn using Prismatic Geoscope's ability by tapping it, adding at least three mana of any color.
3. Activate Trazyn by paying 2, untapping it.
4. Repeat from step 2.

This ingenious loop transforms your graveyard into an engine for infinite mana by letting Trazyn the Infinite inherit the abilities of other key permanents. With Scuttling Sliver quietly granting its untap ability from the graveyard to Trazyn, and Prismatic Geoscope sitting in the graveyard to provide a hefty domain-fueled mana production ability, Trazyn gains the power to tap for a surplus of colored mana. Imagecrafter steps in to ensure Trazyn qualifies as a Sliver for the untap ability, allowing you to pay {2} to untap Trazyn and repeat the process endlessly.
