Sensei's Divining Top + Transplant Theorist + Stone Calendar

Sensei's Divining Top

Transplant Theorist

Stone Calendar

How it works

1. Cast Sensei's Divining Top by paying 0 due to Stone Calendar.
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 clever loop transforms a humble spinning artifact into a relentless card-selection engine. By using Stone Calendar to erase the casting cost of Sensei's Divining Top, you are able to repeatedly cast it for free, instantly triggering Transplant Theorist's loot ability. Before that draw trigger even resolves, you can tap Sensei's Divining Top to draw a card and place itself back on top of your library, allowing the Transplant Theorist trigger to snatch it back to your hand while letting you churn through your deck and pitch unwanted cards to the graveyard.
