Sensei's Divining Top + Traxos, Scourge of Kroog + Elsha of the Infinite + Elven Chorus

Sensei's Divining Top

Traxos, Scourge of Kroog

Elsha of the Infinite

Elven Chorus

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. Elsha and Traxos trigger.
5. Resolve the Elsha trigger, giving itself +1/+1 until end of turn.
6. Resolve the Traxos trigger, untapping it.
7. Repeat.

This fascinating engine turns your topdeck into a self-sustaining loop by leveraging Elven Chorus to grant mana-tapping abilities to your board, including Traxos, Scourge of Kroog, which taps to help pay for the artifact you are trying to cast. With Elsha of the Infinite allowing you to peer at and cast noncreature spells from the top of your library—and giving it flash to boot—you can repeatedly tap Sensei's Divining Top to draw a card and place itself back onto your library. Casting the top right back off the top triggers Elsha of the Infinite's prowess while simultaneously satisfying Traxos, Scourge of Kroog's condition to untap whenever you cast a historic spell, keeping your mana flowing and your draws compounding.
