The Master, Formed Anew

Ruthless Technomancer

Agatha of the Vile Cauldron

Dack's Duplicate

How it works

1. Cast The Master by paying .

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.

This brilliant loop harnesses recursive identity-swapping to continuously sacrifice and resurrect our key pieces. With Agatha of the Vile Cauldron discount-buffing our creatures, The Master, Formed Anew trades places with Dack's Duplicate while Ruthless Technomancer converts their bodies into the Treasures needed to fuel the cycle. Because each iteration leaves behind a trail of sacrifices and resurrections, you generate an endless stream of triggers while pinging back and forth between the graveyard and the battlefield.
