Falco Spara, Pactweaver + Sensei's Divining Top + Cloud Key + Toothy, Imaginary Friend

Falco Spara, Pactweaver

Sensei's Divining Top

Cloud Key

Toothy, Imaginary Friend

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

This clever loop turns your library into a self-sustaining engine by leveraging Falco Spara, Pactweaver to cast spells directly from the top, treating any friendly counter as currency. Cloud Key reduces the cost of that topdecked artifact to zero, allowing Sensei's Divining Top to be repeatedly drawn and replayed for free while constantly generating fresh counters. Meanwhile, Toothy, Imaginary Friend sits on the board to catch every card draw from the Top, swelling with +1/+1 counters that can later be consumed by Falco Spara as the fuel to keep the entire cycle spinning.
