Sensei's Divining Top + Urza, Lord Protector + Experimental Frenzy

Sensei's Divining Top

Urza, Lord Protector

Experimental Frenzy

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

By utilizing Experimental Frenzy, you gain the ability to cast Sensei's Divining Top directly from the top of your library. The cost-reduction provided by Urza, Lord Protector drops the casting cost of Sensei's Divining Top down to zero, allowing you to continually tap the artifact to draw a card and place it back on top of your library, only to immediately recast it for free. This creates an endless loop that generates infinite card draw, infinite draw triggers, and a near-infinite storm count.
