Sensei's Divining Top + Traxos, Scourge of Kroog + Earthcraft + Future Sight

Sensei's Divining Top

Traxos, Scourge of Kroog

Earthcraft

Future Sight

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 loop turns the top of your library into an endless engine, fueled by Future Sight allowing you to cast spells directly from that zone. You can continually tap your basic land for mana, utilizing Earthcraft to tap Traxos, Scourge of Kroog instead of a traditional creature. That mana pays to cast Sensei's Divining Top from the top of your library, which conveniently triggers Traxos, Scourge of Kroog to untap itself via its historic status. Finally, resolving Sensei's Divining Top's own ability lets you draw a card while tucking it right back onto the library, keeping the sequence endlessly self-sustaining.
