Sensei's Divining Top + One with the Multiverse + Temur Battlecrier

Sensei's Divining Top

One with the Multiverse

Temur Battlecrier

How it works

1. Activate Sensei's Divining Top by tapping it, causing you to draw a card and put Sensei's Divining Top on top of your library.
2. Cast Sensei's Divining Top from the top of your library by paying 0.
3. Repeat

This clever little engine turns the top of your library into a self-sustaining casting loop, fueled entirely by the synergy between Sensei's Divining Top and One with the Multiverse. With One with the Multiverse granting you the ability to cast spells directly from the top of your library, you can continuously tap Sensei's Divining Top to draw a card and place itself back on library's summit, only to immediately recast it for free. While Temur Battlecrier's cost-reduction isn't strictly necessary when you're casting the artifact for zero mana, this hypnotic dance ultimately generates infinite card draw, infinite draw triggers, and a near-infinite storm count for formats like commander, oathbreaker, and vintage.
