The Master, Formed Anew + Ruthless Technomancer + Evil Twin + Agatha of the Vile Cauldron

The Master, Formed Anew

Ruthless Technomancer

Evil Twin

Agatha of the Vile Cauldron

How it works

1. Cast The Master by paying .
2. When The Master enters the battlefield, it triggers, causing you to sacrifice Evil Twin 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 Evil Twin from your graveyard to the battlefield as a copy of The Master, which causes the Evil Twin to be a copy of Ruthless Technomancer.
5. When Evil Twin 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 Evil Twin 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 brilliant loop plays out as an endless game of tag between The Master, Formed Anew and Evil Twin, using Ruthless Technomancer to continuously sacrifice them and generate the Treasures needed to fund their recursion. Because Agatha of the Vile Cauldron is a non-bo here (her cost-reduction ability doesn't apply to the Technomancer's activated mana cost), the engine runs purely on the mana produced by sacrificing the creatures for Treasure tokens. By alternating which copy enters the battlefield as the Technomancer, you achieve an infinite loop of entry, death, and sacrifice triggers.
