The Master, Formed Anew

Ruthless Technomancer

Progenitor Mimic

Training Grounds

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 loop achieves infinite sacrifices and death triggers by bouncing a pair of creatures back and forth between the battlefield and the graveyard, completely fueled by Training Grounds making the recursion cheap enough to sustain. You begin by using The Master, Formed Anew: Body Thief to exile Progenitor Mimic, which then lets Ruthless Technomancer step in to sacrifice creatures and churn out Treasure tokens. Those Treasures provide the exact mana needed to activate the graveyard ability, allowing the copies to continually resurrect each other while generating endless triggers.
