Falco Spara, Pactweaver

Sensei's Divining Top

Yotian Dissident

Cloud Key

How it works

1. 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.
2. Cast Sensei's Divining Top from the top of your library by paying 0 and removing a counter from a creature you control.
3. When Sensei's Divining Top enters, Yotian Dissident triggers, putting a +1/+1 counter on Yotian Dissident.
4. Repeat.

This intricate machinery transforms the humble Sensei's Divining Top into an infinite card-drawing engine by repeatedly cycling it to the top of your library and casting it for free. The entire loop is subsidized by Cloud Key, which reduces the artifact's cost to zero, and Falco Spara, Pactweaver, whose passive ability lets you cast spells from the top of your library while turning your counters into an alternative payment currency. Meanwhile, Yotian Dissident acts as the physical heart of the operation, replenishing those spent counters every single time Sensei's Divining Top re-enters the battlefield as an artifact.
