The Master, Formed Anew + Ruthless Technomancer + Agatha of the Vile Cauldron + Vesuvan Shapeshifter

The Master, Formed Anew

Ruthless Technomancer

Agatha of the Vile Cauldron

Vesuvan Shapeshifter

How it works

1. Cast The Master by paying .
2. When The Master enters the battlefield, it triggers, causing you to sacrifice Vesuvan Shapeshifter 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 Shapeshifter from your graveyard to the battlefield as a copy of The Master, which causes the Vesuvan Shapeshifter to be a copy of Ruthless Technomancer.
5. When Vesuvan Shapeshifter 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 Shapeshifter 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 recursive loop hinges on a clever identity-copying dance between The Master, Formed Anew: Body Thief and Vesuvan Shapeshifter, allowing them to continually enter the battlefield as each other and as Ruthless Technomancer. Since Agatha of the Vile Cauldron is present, her static cost-reduction ability alters the math—though her text notes it can't reduce mana costs below one mana, Ruthless Technomancer's resurrection ability still only costs {2}{B}, and by sacrificing the Treasures generated upon each creature's entry, you easily fund the loop. As this triad alternates sacrifices and returns, you generate infinite entry, leave-the-battlefield, sacrifice, and death triggers to fuel your strategy.
