Sensei's Divining Top + Traxos, Scourge of Kroog + Magus of the Future + Utopia Vow

Sensei's Divining Top

Traxos, Scourge of Kroog

Magus of the Future

Utopia Vow

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 crafty loop turns the normally restrictive drawback of Utopia Vow into a mana-generating asset for Traxos, Scourge of Kroog, allowing the massive construct to tap for {1} instead of attacking or blocking. With Magus of the Future revealing the top of your library and letting you play cards directly from it, you can repeatedly tap and recast Sensei's Divining Top. Every time you cast the Top, its status as an artifact triggers Traxos, Scourge of Kroog to untap, readying the creature to tap for mana again to pay for the next casting cost and fueling an endless cycle of draws and artifact triggers.
