Scuttling Sliver + Trazyn the Infinite + The Eternity Elevator + Maskwood Nexus

Scuttling Sliver

Trazyn the Infinite

The Eternity Elevator

Maskwood Nexus

How it works

1. Activate Trazyn using The Eternity Elevator's ability by tapping it, adding CCC
2. Activate Trazyn by paying 2, untapping it.
3. Repeat.

This clever engine lets Trazyn the Infinite swallow the activated abilities of every artifact in your graveyard, turning it into a massive one-card powerhouse. Maskwood Nexus pulls the final trick by turning Trazyn into a Sliver, which crucially grants it Scuttling Sliver's untap ability. With those pieces assembled, Trazyn can tap to produce three colorless mana using The Eternity Elevator, spend two of that mana to untap itself via the Sliver ability, and loop the process indefinitely for infinite colorless mana.
