Sensei's Divining Top + Traxos, Scourge of Kroog + Magus of the Future + A Realm Reborn

Sensei's Divining Top

Traxos, Scourge of Kroog

Magus of the Future

A Realm Reborn

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 looping engine is fueled by A Realm Reborn, which grants all your other permanents the crucial ability to tap for mana. With that color-fixing foundation in place, you tap Traxos, Scourge of Kroog for mana to pay for Sensei's Divining Top's activation, drawing a card while tucking the Top safely onto your library. Meanwhile, Magus of the Future lets you play the Top directly from the top of your library, making it a historic spell that triggers Traxos, Scourge of Kroog to untap and start the cycle anew.
