Sensei's Divining Top + Traxos, Scourge of Kroog + Enduring Vitality + Madame Web, Clairvoyant

Sensei's Divining Top

Traxos, Scourge of Kroog

Enduring Vitality

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 clever loop relies on the constant recycling of Sensei's Divining Top right off the top of your library, made possible because Madame Web, Clairvoyant lets you cast noncreature spells from that very spot. To fund this loop, Enduring Vitality quietly grants your creatures the ability to tap for mana, turning Traxos, Scourge of Kroog into a proactive mana source. Normally, Traxos, Scourge of Kroog is weighed down by its restriction of not untapping during your untap step, but its second ability rewards you by untapping itself every time you cast a historic spell like Sensei's Divining Top. By tapping Traxos, Scourge of Kroog for mana via Enduring Vitality's granted ability, drawing a card while tucking Sensei's Divining Top away, and immediately casting it again through Madame Web, Clairvoyant's permission, you create a self-sustaining engine of endless draws and artifact triggers.
