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.
Cast Sensei's Divining Top from the top of your library by paying 1.
Traxos triggers, untapping itself.
Repeat.
This intricate loop transforms your deck's top card into a self-sustaining engine by uniting Citanul Hierophants with Traxos, Scourge of Kroog to turn your creatures into mana sources. With Mystic Forge granting you the ability to cast artifacts right off the top of your library, you can repeatedly deploy Sensei's Divining Top for a single mana. Each time you cast that historic spell, Traxos untaps itself to restart the green mana production, while the Top itself replaces the card you just drew and puts itself back on top to be recast endlessly.
