Sensei's Divining Top + Traxos, Scourge of Kroog + Elven Chorus + Madame Web, Clairvoyant

Sensei's Divining Top

Traxos, Scourge of Kroog

Elven Chorus

Madame Web, Clairvoyant

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 cunning engine puts the legendary mechanical power of Sensei's Divining Top right on top of your library where Elven Chorus and Madame Web, Clairvoyant can both see it, letting you cast it repeatedly right off the top. As an artifact, every time that Top hits the stack, it triggers Traxos, Scourge of Kroog to untap. Once Traxos is untapped, its tap ability provides the exact {1} mana needed to recast the Top, while Elven Chorus simultaneously grants all your creatures the ability to tap for mana just in case.
