Sensei's Divining Top + Echoes of Eternity + Starnheim Courser

Sensei's Divining Top

Echoes of Eternity

Starnheim Courser

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 brilliant loop transforms a humble artifact into an endless engine of discovery, all made possible by cost reduction and effortless self-replication. With Starnheim Courser discounting artifacts, Sensei's Divining Top becomes completely free to cast, immediately catching the eye of Echoes of Eternity. That massive enchantment doubles every trigger and copies every colorless spell you cast, turning a single cast into two separate artifacts entering the battlefield. Once you have both the real artifact and a token copy in play, you can tap them in an alternating rhythm: one goes to the top of your library to draw a card, while the other draws you the first Top right back.
