The Master, Formed Anew + Ruthless Technomancer + Zirda, the Dawnwaker + Vesuvan Doppelganger

The Master, Formed Anew

Ruthless Technomancer

Zirda, the Dawnwaker

Vesuvan Doppelganger

How it works

1. Cast The Master by paying .
2. When The Master enters the battlefield, it triggers, causing you to sacrifice Vesuvan Doppelganger 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 Vesuvan Doppelganger from your graveyard to the battlefield as a copy of The Master, which causes the Vesuvan Doppelganger to be a copy of Ruthless Technomancer.
5. When Vesuvan Doppelganger 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 Vesuvan Doppelganger 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 graveyard and the battlefield using Ruthless Technomancer's reanimation ability. The Master, Formed Anew: Body Thief starts the chain by exiling Vesuvan Doppelganger and entering as a copy of it, which allows Vesuvan Doppelganger to enter as a copy of Ruthless Technomancer and sacrifice The Master for Treasure tokens. Because Zirda, the Dawnwaker reduces the activation cost of the Technomancer ability down to just one mana, you can easily use those newly created Treasures to continuously pull the sacrificed creatures right back out of the graveyard.
