Sensei's Divining Top + Echoes of Eternity + Jhoira's Familiar

Sensei's Divining Top

Echoes of Eternity

Jhoira's Familiar

How it works

1. Cast Sensei's Divining Top by paying 0.
2. Echoes of Eternity triggers, creating a copying the Sensei's Divining Top spell.
3. Resolve both Sensei's Divining Top spells.
4. Activate the nontoken Sensei's Divining Top by tapping it, causing you to draw a card and put Sensei's Divining Top from the battlefield onto the top of your library.
5. Activate the token Sensei's Divining Top by tapping it, causing you to draw Sensei's Divining Top, and causing you to put the token Sensei's Divining Top from the battlefield onto the top of your library.
6. Repeat.

This clever loop takes advantage of the fact that Sensei's Divining Top is a historic artifact, allowing Jhoira's Familiar to reduce its casting cost to zero. When you cast it for free, Echoes of Eternity steps in with its passive triggered ability to copy the spell, netting you two Tops for the price of zero mana. From there, you can tap both the original and the token Sensei's Divining Top to draw cards and bounce themselves back to your library, establishing a self-sustaining cycle that endlessly repeats to net you infinite draws and an overwhelming storm count.
