Sensei's Divining Top + Traxos, Scourge of Kroog + Mystic Forge + Earthcraft

Sensei's Divining Top

Traxos, Scourge of Kroog

Mystic Forge

Earthcraft

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 ingenious loop turns your library into an endless engine by leveraging Mystic Forge to let you cast artifacts directly off the top. As you tap Sensei's Divining Top to draw a card and place itself back on top of your library, you can immediately recast it for one mana. To sustain the mana flow, Earthcraft taps the slumbering Traxos, Scourge of Kroog to untap a basic land—and every time you cast that historic top artifact, Traxos untaps itself to keep the creature-tapping going.
