Sensei's Divining Top + Transplant Theorist + Semblance Anvil

Sensei's Divining Top

Transplant Theorist

Semblance Anvil

How it works

1. Cast Sensei's Divining Top by paying 0 due to Semblance Anvil.
2. When Sensei's Divining Top enters, Transplant Theorist triggers.
3. Holding priority, activate Sensei's Divining Top by tapping it, causing you to draw a card and put Sensei's Divining Top on top of your library.
4. Resolve the Transplant Theorist trigger, causing you to draw Sensei's Divining Top from your library, and then discard a card other than Sensei's Divining Top.
5. Repeat

This ingenious loop transforms Sensei's Divining Top into a free, self-replacing spell by leveraging Semblance Anvil to reduce its cost to zero. As the Top repeatedly enters the battlefield, Transplant Theorist provides the crucial bridge by turning each entry into a draw trigger, allowing you to cycle the artifact back into your hand through looting while steadily feeding your graveyard. The beauty of the stack manipulation here is that you can tap the Top in response to its own entry trigger to draw a card, ensuring it returns to the top of your library just in time to be drawn by the Theorist.
