Scuttling Sliver + Trazyn the Infinite + Empowered Autogenerator + Amorphous Axe

Scuttling Sliver

Trazyn the Infinite

Empowered Autogenerator

Amorphous Axe

How it works

1. Activate Trazyn using Empowered Autogenerator's ability by tapping it, putting a charge counter on it and adding one mana of any color for each charge counter on it.
2. Activate Trazyn by paying 2, untapping it.
3. Repeat.

This clever loop turns Trazyn the Infinite into a one-man mana engine by turning your graveyard into a workshop of stolen potential. With Amorphous Axe in the graveyard, Trazyn safely gains all creature types—including Sliver—allowing Scuttling Sliver's activated ability from the graveyard to grant him a cheap untap mechanism for just two mana. Meanwhile, Empowered Autogenerator sits on the battlefield quietly gathering charge counters, its activated ability also absorbed by Trazyn so that tapping him generates an escalating amount of colored mana. By alternating the Autogenerator's mana-producing tap with the Scuttling Sliver's untap, Trazyn endlessly fuels his own activation costs, netting infinite colored mana in the process.
