Sensei's Divining Top + Birgi, God of Storytelling // Harnfel, Horn of Bounty + Magus of the Future

Sensei's Divining Top

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

Magus of the Future

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.
3. Birgi triggers, adding .
4. Repeat.

This engine relies on Sensei's Divining Top's unique ability to replace itself on top of your library, allowing you to continually recast it for just one mana. Magus of the Future makes this loop self-sustaining by letting you cast the artifact directly from the top of your library without ever needing to hold it in your hand. Meanwhile, Birgi, God of Storytelling // Harnfel, Horn of Bounty converts every single casting of the Top into a net-positive mana source, fueling the loop infinitely while generating an astronomical storm count and drawing your entire deck.
