Sensei's Divining Top + Transplant Theorist + Ballad of the Black Flag

Sensei's Divining Top

Transplant Theorist

Ballad of the Black Flag

How it works

1. Cast Sensei's Divining Top by paying 0 due to Ballad of the Black Flag.
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 delightful loop turns your deck into a self-cycling engine by leaning heavily on Ballad of the Black Flag's final chapter, which reduces the cost of historic spells so that Sensei's Divining Top can be cast for free. As the Top repeatedly enters the battlefield, Transplant Theorist's passive ability triggers to let you loot, drawing the very card you just put on top of your library via its own tap ability. The synergy ensures that Transplant Theorist's activated ability isn't even needed to recover your pieces, letting you continuously spin the Top into an endless flurry of artifact entries and card draw.
