Falco Spara, Pactweaver + Sensei's Divining Top + Toothy, Imaginary Friend + Cemetery Prowler

Falco Spara, Pactweaver

Sensei's Divining Top

Toothy, Imaginary Friend

Cemetery Prowler

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 the top of your library into an endless engine, fueled by the alternate casting cost granted by Falco Spara, Pactweaver. By tapping Sensei's Divining Top to draw a card and place itself back on top, you trigger Toothy, Imaginary Friend to grow with a new +1/+1 counter. You can then immediately recast Sensei's Divining Top from your library for zero mana by removing that freshly minted counter to satisfy Falco Spara's payment requirement. Meanwhile, Cemetery Prowler sits on the board quietly lowering the artifact's mana cost, ensuring the whole operation runs smoothly without ever draining your mana reserves.
