Sensei's Divining Top + Birgi, God of Storytelling // Harnfel, Horn of Bounty + Rook Turret

Sensei's Divining Top

Birgi, God of Storytelling // Harnfel, Horn of Bounty

Rook Turret

How it works

1. Cast Sensei's Divining Top by paying 1
2. Birgi triggers, adding
3. When Sensei's Divining Top enters, Rook Turret triggers.
4. 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.
5. 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.
6. Repeat

This ingenious loop transforms Sensei's Divining Top into a self-sustaining engine by leveraging the passive mana generation of Birgi, God of Storytelling whenever you recast it. As the artifact repeatedly enters the battlefield, Rook Turret steps in with its triggered ability to instantly cycle the Top back into your hand while filtering through your graveyard via discard. The result is a continuous loop of casting and redrawing that generates an endless stream of triggers and storm count without ever running out of resources.
