The Master, Formed Anew + Ruthless Technomancer + Zirda, the Dawnwaker + Dack's Duplicate

The Master, Formed Anew

Ruthless Technomancer

Zirda, the Dawnwaker

Dack's Duplicate

How it works

1. Cast The Master by paying .
2. When The Master enters the battlefield, it triggers, causing you to sacrifice Dack's Duplicate 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 Dack's Duplicate from your graveyard to the battlefield as a copy of The Master, which causes the Dack's Duplicate to be a copy of Ruthless Technomancer.
5. When Dack's Duplicate 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 Dack's Duplicate 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 to continuously trigger sacrifices and enter-the-battlefield effects. By utilizing The Master, Formed Anew and Dack's Duplicate to endlessly copy Ruthless Technomancer, you can sacrifice one to the other's entry trigger to generate Treasures, then feed those Treasures back into Ruthless Technomancer's resurrection ability to bring the other copy right back. Zirda, the Dawnwaker sits quietly in the background as your engine's best friend, reducing the activation cost of Ruthless Technomancer's ability so you can afford to keep the cycle spinning infinitely.
