Sensei's Divining Top + Stone Calendar + Future Sight

Sensei's Divining Top

Stone Calendar

Future Sight

How it works

1. Activate Sensei's Divining Top 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 0.
3. Repeat

This loop turns the top of your library into your hand, letting you cycle through your entire deck at zero cost. Future Sight does the heavy lifting by allowing you to cast Sensei's Divining Top directly from the top of your library, while Stone Calendar quietly removes the artifact's mana cost so you can recast it for free. Every time you tap Sensei's Divining Top to draw a card and place it back on top of your library, you can immediately cast it again, generating endless draw triggers and building a massive storm count.
