The Master, Formed Anew + Ruthless Technomancer + Agatha of the Vile Cauldron + Synth Infiltrator

The Master, Formed Anew

Ruthless Technomancer

Agatha of the Vile Cauldron

Synth Infiltrator

How it works

1. Cast The Master by paying .
2. When The Master enters the battlefield, it triggers, causing you to sacrifice Synth Infiltrator and create at least two Treasure tokens.
3. Activate a Treasure by tapping and sacrificing it, adding .
4. Activate The Master by paying and sacrificing a Treasure, returning Synth Infiltrator from your graveyard to the battlefield as a copy of The Master, which causes the Synth Infiltrator to be a copy of Ruthless Technomancer.
5. When Synth Infiltrator enters the battlefield, it triggers, causing you to sacrifice The Master and create two Treasure tokens.
6. Activate a Treasure by tapping and sacrificing it, adding .
7. Activate Synth Infiltrator by paying and sacrificing a Treasure, returning The Master from your graveyard to the battlefield as a copy of Ruthless Technomancer.
8. Repeat from step 2.

This intricate loop relies on a clever shell game between the graveyard and the battlefield, with Agatha of the Vile Cauldron quietly enabling the engine by discounting activated abilities based on her power. You use The Master, Formed Anew: Body Thief and Synth Infiltrator to continuously copy each other while leveraging Ruthless Technomancer's sacrifice ability to turn those recurring creature entries into a steady stream of Treasure tokens. By cycling back and forth between the two copy-creatures and funding their resurrection costs with the generated artifacts, you create an endless cycle of entries, leaves, and sacrifices.
