How it works
Cast The Master either from your hand or from the command zone by paying plus command tax, if applicable, choosing to have it enter the battlefield as a copy of Ruthless Technomancer.
When The Master enters the battlefield, it triggers, causing you to sacrifice Flesh Duplicate and create at least two Treasure tokens.
Activate a Treasure by tapping and sacrificing it, adding .
Activate The Master by paying and sacrificing a Treasure, returning Flesh Duplicate from your graveyard to the battlefield as a copy of The Master, which causes the Flesh Duplicate to be a copy of Ruthless Technomancer.

Activate Flesh Duplicate by paying and sacrificing a Treasure, returning The Master from your graveyard to the battlefield as a copy of Ruthless Technomancer.
Repeat from step 2.
This ingenious recursion loop relies on casting The Master, Formed Anew: Body Thief and immediately letting it enter as a copy of Ruthless Technomancer to feed on your other creatures. To get the engine running, Flesh Duplicate enters the battlefield as a copy of anything available to provide a sacrificial target for Ruthless Technomancer's entry trigger, generating the initial Treasure tokens needed to fund the cycle. From there, Training Grounds plays a vital role by reducing the activation cost of Ruthless Technomancer's recursion ability down to just {B}, making it cheap enough to loop endlessly. By repeatedly sacrificing The Master, Formed Anew: Body Thief and Flesh Duplicate back and forth to each other's cloned Technomancer abilities using the generated Treasures, you generate an infinite stream of enter-the-battlefield, leave-the-battlefield, and death triggers.
