Scuttling Sliver + Trazyn the Infinite + Maskwood Nexus + Prismatic Geoscope

Scuttling Sliver

Trazyn the Infinite

Maskwood Nexus

Prismatic Geoscope

How it works

1. Activate Trazyn using Prismatic Geoscope's ability by tapping it, adding at least three mana of any color.
2. Activate Trazyn by paying 2, untapping it.
3. Repeat.

With Maskwood Nexus granting your creatures every creature type across all zones, Scuttling Sliver ensures that every creature you control—including Trazyn the Infinite—gains the ability to untap itself for just two mana. This creates a clever loop where Trazyn adopts the activated abilities of any artifact in your graveyard, specifically leveraging Prismatic Geoscope to tap for mana that exceeds the cost to untap. By cycling between tapping the Geoscope's stolen ability for a surplus of mana and paying the Sliver's cost to untap, you generate an infinite reservoir of colored mana.
