Sensei's Divining Top + Transplant Theorist + Starnheim Courser

Sensei's Divining Top

Transplant Theorist

Starnheim Courser

How it works

1. Cast Sensei's Divining Top by paying 0 due to Starnheim Courser.
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 lets you spin your library into an endless engine of discovery, fueled entirely by cost reduction and clever stack manipulation. Starnheim Courser does the heavy lifting up front by making artifact spells free, allowing Sensei's Divining Top to enter the battlefield for zero mana. As soon as it touches the table, Transplant Theorist spots the new artifact and triggers its rumbling loot effect; by holding priority and tapping the Top in response to draw a card and tuck itself away, you set up the Theorist's resolution to draw that very same Top right back into your hand. Discarding a card along the way turns this perpetual motion machine into infinite draw triggers, endless looting, and a towering storm count.
