Scuttling Sliver + Trazyn the Infinite + Thran Dynamo + Imagecrafter

Scuttling Sliver

Trazyn the Infinite

Thran Dynamo

Imagecrafter

How it works

1. Activate Imagecrafter by tapping it, causing Trazyn to become a Sliver until end of turn.
2. Activate Trazyn using Thran Dynamo's ability by tapping it, adding CCC
3. Activate Trazyn by paying 2, untapping it.
4. Repeat from step 2.

This ingenious loop turns Trazyn the Infinite into a self-sustaining mana engine by exploiting its graveyard-copying ability. With Thran Dynamo sitting in your graveyard, Trazyn gains the ability to tap for three colorless mana, more than paying for the untap ability granted by Scuttling Sliver's presence in your graveyard. To tie it all together, Imagecrafter steps in to temporarily turn Trazyn into a Sliver, ensuring it officially qualifies for the Scuttling Sliver ability that fuels the entire infinite untap and mana loop.
