Falco Spara, Pactweaver

Sensei's Divining Top

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

Lyla, Holographic Assistant

How it works

1. Activate Sensei's Divining Top's second ability by tapping it, causing you to draw a card and put Sensei's Divining Top on top of your library.
2. Lyla triggers, putting a +1/+1 counter on it.
3. Cast Sensei's Divining Top from the top of your library by paying 1 and removing a counter from a creature you control.
4. Birgi triggers, adding .
5. Repeat.

This looping engine turns a simple top-deck manipulation tool into a self-sustaining draw machine by constantly recycling Sensei's Divining Top right back to the library. Falco Spara, Pactweaver provides the vital alternative casting permission, letting you play the Top directly off the library by cashing in counters. Every time you draw that Top, Lyla, Holographic Assistant triggers to place a fresh +1/+1 counter on a creature, which directly replenishes the exact resource Falco Spara needs to keep the casting going. Finally, Birgi, God of Storytelling fuels the entire loop's mana cost by refunding red mana with each spell cast, allowing you to repeat the cycle indefinitely.
