Scuttling Sliver + Trazyn the Infinite + Empowered Autogenerator + Trickery Charm

Scuttling Sliver

Trazyn the Infinite

Empowered Autogenerator

Trickery Charm

How it works

1. Cast Trickery Charm by paying , causing Trazyn to become a Sliver until end of turn.
2. 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 Trazyn.
3. Activate Trazyn by paying 2, untapping it.
4. Repeat from step 2.

This clever brew turns the graveyard into a powerhouse by letting Trazyn the Infinite inherit the activated abilities of any artifact cards lingering within it, specifically leveraging the escalating mana production of Empowered Autogenerator. Since Empowered Autogenerator starts out producing zero mana, we need a way to build up its charge counters without repeatedly tapping and untapping it, which is where Scuttling Sliver comes in to grant Trazyn a built-in untap ability. To tie the whole engine together, Trickery Charm is cast to temporarily turn Trazyn into a Sliver, bridging the gap between the creature types so that Trazyn can access Scuttling Sliver's untap power and fuel an infinite loop of colored mana.
