Sensei's Divining Top + Cemetery Prowler + The Reality Chip

Sensei's Divining Top

Cemetery Prowler

The Reality Chip

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 loop turns the classic Sensei's Divining Top into an endless engine by reducing its casting cost to zero, entirely bypassing its normal mana investment. This is made possible by Cemetery Prowler, whose static ability discounts your artifact spells based on the exiled cards it has consumed. Meanwhile, The Reality Chip grants you the ability to cast that very top from the top of your library whenever it is attached to a creature. By simply tapping the Top to draw a card and place it back on your library, you can immediately cast it for free with the Prowler's discount, repeating the process as many times as you desire to draw your entire deck and generate an astronomical storm count.
