The Master, Formed Anew + Ruthless Technomancer + Progenitor Mimic + Zirda, the Dawnwaker

The Master, Formed Anew

Ruthless Technomancer

Progenitor Mimic

Zirda, the Dawnwaker

How it works

1. Cast The Master by paying .
2. When The Master enters the battlefield, it triggers, causing you to sacrifice Progenitor Mimic 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 Progenitor Mimic from your graveyard to the battlefield as a copy of The Master, which causes the Progenitor Mimic to be a copy of Ruthless Technomancer.
5. When Progenitor Mimic 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 Progenitor Mimic 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 clever loop relies on trading identities back and forth between The Master, Formed Anew and Progenitor Mimic, using Ruthless Technomancer as the engine that recycles them both from the graveyard. Whenever a copy enters the battlefield as Ruthless Technomancer, its sacrifice trigger generates enough Treasure tokens to fuel the Technomancer's activated ability—a cost made even more efficient by Zirda, the Dawnwaker reducing those activation costs by {2}. By continuously looping these creatures in and out of the graveyard, you generate an endless stream of sacrifice and death triggers.
