The Master, Formed Anew + Ruthless Technomancer + Agatha of the Vile Cauldron + Mercurial Pretender

The Master, Formed Anew

Ruthless Technomancer

Agatha of the Vile Cauldron

Mercurial Pretender

How it works

1. Cast The Master by paying .
2. When The Master enters the battlefield, it triggers, causing you to sacrifice Mercurial Pretender 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 Mercurial Pretender from your graveyard to the battlefield as a copy of The Master, which causes the Mercurial Pretender to be a copy of Ruthless Technomancer.
5. When Mercurial Pretender 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 Mercurial Pretender 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 elegant loop leverages The Master, Formed Anew and Mercurial Pretender to eternally copy Ruthless Technomancer, turning a simple recursion engine into an endless cycle of sacrifices. As these creatures repeatedly enter and leave the battlefield, Ruthless Technomancer's entrance trigger continually generates Treasure tokens to pay for its own revival ability. Meanwhile, Agatha of the Vile Cauldron lurks in the background, though here the combo relies purely on the cyclical interplay of cloning, sacrificing, and recurring to fuel the engine indefinitely.
