The Master, Formed Anew + Ruthless Technomancer + Agatha of the Vile Cauldron + Progenitor Mimic

The Master, Formed Anew

Ruthless Technomancer

Agatha of the Vile Cauldron

Progenitor Mimic

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 ingenious recursion loop relies on The Master, Formed Anew and Progenitor Mimic endlessly trading places with the help of Ruthless Technomancer. Thanks to Agatha of the Vile Cauldron's cost-reducing passive ability, the Technomancer's reanimation ability costs a single mana to activate, allowing a cycled Treasure to fully fund it. As the creatures continually re-enter and sacrifice one another, their combined abilities generate an infinite loop of entry, death, and sacrifice triggers.
