This elegant loop lets you draw your entire deck by exploiting the synergy between the top of your library and your battlefield. Magus of the Future and Elven Chorus work in tandem to let you cast Sensei's Divining Top directly from the top of your library, while Elven Chorus conveniently turns Traxos, Scourge of Kroog into a mana source that taps for the exact {1} needed to recast it. Whenever you tap Traxos for mana, you can tap Sensei's Divining Top to draw a card and place itself back on top of your library; casting it then triggers Traxos, Scourge of Kroog to untap, making the whole cycle self-sustaining.
