Sensei's Divining Top

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

Lorescale Coatl

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. Lorescale Coatl 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 clever loop transforms Sensei's Divining Top into a self-sustaining engine by letting you repeatedly draw it and recast it from the top of your library. Falco Spara, Pactweaver provides the vital alternate cost by trading away a counter from a creature you control instead of paying the artifact's mana cost, and Birgi, God of Storytelling conveniently refunds red mana with each spell cast to keep the cycle going. Meanwhile, Lorescale Coatl happily feasts on every single card draw, growing larger with each iteration as you churn through your deck.
