Sensei's Divining Top + Traxos, Scourge of Kroog + Earthcraft + Mm'menon, the Right Hand

Sensei's Divining Top

Traxos, Scourge of Kroog

Earthcraft

Mm'menon, the Right Hand

How it works

1. Activate a basic land by tapping it, adding 1.
2. Activate Earthcraft by tapping Traxos, untapping a basic land.
3. 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.
4. Cast Sensei's Divining Top from the top of your library by paying 1.
5. Traxos triggers, untapping itself.
6. Repeat.

This elegant engine relies on Mm'menon, the Right Hand to peer at the top of your library and turn your artifacts into mana sources that pay exclusively to cast spells from outside your hand, which conveniently covers Sensei's Divining Top once it puts itself back on top. While Earthcraft normally needs a living creature, it can happily tap the stubborn, otherwise-dormant Traxos, Scourge of Kroog to untap a basic land and generate the exact mana needed to replay the Top. Every single cycle sees Sensei's Divining Top trigger Traxos to untap itself so it can be tapped to Earthcraft all over again, creating a self-sustaining loop that continually draws cards and triggers your artifact effects.
