Falco Spara, Pactweaver + Sensei's Divining Top + Stone Calendar + Clinquant Skymage

Falco Spara, Pactweaver

Sensei's Divining Top

Stone Calendar

Clinquant Skymage

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. Clinquant Skymage 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 by leveraging Falco Spara, Pactweaver's ability to cast spells using counters instead of mana. With Stone Calendar discounting the artifact's cost down to zero, you can repeatedly tap Sensei's Divining Top to draw a card and send it back to the library, only to cast it right back off the top. Every single time you draw that card, Clinquant Skymage triggers to effortlessly supply the fresh +1/+1 counters that Falco Spara, Pactweaver needs to keep fueling the process.
