Falco Spara, Pactweaver

Sensei's Divining Top

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

Mm'menon, Uthros Exile

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. Cast Sensei's Divining Top from the top of your library by paying 1 and removing a counter from a creature you control.
3. Birgi triggers, adding
4. When Sensei's Divining Top enters, Mm'menon triggers, putting a +1/+1 counter on Mm'menon.
5. Repeat.

This elegant loop lets you draw your entire deck by exploiting the synergy between Sensei's Divining Top and Falco Spara, Pactweaver, which lets you cast that very same Top straight off the top of your library by trading away a counter instead of paying its normal mana cost. Every time you cast the Top, Birgi, God of Storytelling rewards you with a red mana to help fund the operation, while Mm'menon, Uthros Exile ensures that the loop perpetually replenishes its own fuel by stacking fresh +1/+1 counters back onto your creatures whenever the artifact re-enters the battlefield.
