Sensei's Divining Top

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

Arcbound Crusher

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, Arcbound Crusher triggers, putting a +1/+1 counter on Arcbound Crusher.
5. Repeat.

This clever loop lets you draw your entire deck by exploiting Sensei's Divining Top's unique ability to put itself back on top of your library when activated. Falco Spara, Pactweaver makes this possible by allowing you to recast the Top right off the library, using its static ability to trade a creature's counter instead of mana for the cost. Meanwhile, Birgi, God of Storytelling continuously refunds your mana investment with red mana every time the Top is cast, fueling the loop infinitely. As an added bonus, the repeated entries trigger Arcbound Crusher to grow to astronomical sizes while cycling through your deck.
