Sensei's Divining Top + Rook Turret + Ballad of the Black Flag

Sensei's Divining Top

Rook Turret

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, Rook Turret 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 Rook Turret 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 the humble Sensei's Divining Top into an endless recycling engine, fueled entirely by the cost-reduction milestone on chapter IV of Ballad of the Black Flag to cast the artifact for free. As Sensei's Divining Top enters the battlefield, Rook Turret provides the crucial passive trigger that lets you loot away unwanted cards while digging right back to your trusty Top. By tapping Sensei's Divining Top in response to its own entry trigger—drawing a card and placing itself neatly back on top of your library—you set up the Rook Turret's loot effect to immediately draw the Top back into your hand, letting you repeat the whole dance indefinitely for infinite storm and card filtering.
