Sensei's Divining Top + Traxos, Scourge of Kroog + Elven Chorus + The Lunar Whale

Sensei's Divining Top

Traxos, Scourge of Kroog

Elven Chorus

The Lunar Whale

How it works

1. Activate Traxos by tapping it, adding 1.
2. 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.
3. Cast Sensei's Divining Top from the top of your library by paying 1.
4. Traxos triggers, untapping itself.
5. Repeat.

This clever loop transforms Sensei's Divining Top into a self-sustaining engine by repeatedly drawing and recasting it from the top of your library. The process is completely funded by Traxos, Scourge of Kroog, which gains a mana-producing tap ability courtesy of Elven Chorus and untaps itself every time you cast the historic artifact. Meanwhile, The Lunar Whale helps round out the top-deck utility by letting you look at the top of your library at any time, ensuring you always see the pieces you need to keep the artifact flowing endlessly.
