Sensei's Divining Top + Echoes of Eternity + Stone Calendar

Sensei's Divining Top

Echoes of Eternity

Stone Calendar

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 dazzling loop turns a humble artifact into an endless engine of discovery, fueled entirely by cost reduction and permanent duplication. With Stone Calendar on the field, casting Sensei's Divining Top becomes completely free, allowing Echoes of Eternity to step in and double the excitement by creating an extra copy of the spell. Once both versions are safely on the battlefield as permanents, their tap abilities feed directly into each other—tapping the real one draws a card and tucks it away, while tapping the token draws that same card right back while tucking itself into library oblivion.
