Falco Spara, Pactweaver + Sensei's Divining Top + Surge Conductor + Stone Calendar

Falco Spara, Pactweaver

Sensei's Divining Top

Surge Conductor

Stone Calendar

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 Diving 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 the battlefield, Surge Conductor triggers, putting a counter on a creature you control that already has a counter on it.
4. Repeat.

This clever loop turns the top of your library into an endless engine for card draw by constantly recycling Sensei's Divining Top. Falco Spara, Pactweaver grants you the vital ability to cast that Top directly from your library while bypassing its mana cost through its alternate payment, feeding the counter it removes right back onto your board. Meanwhile, Stone Calendar reduces the casting cost to zero, making the loop entirely free, and Surge Conductor triggers off the returning artifact to proliferate your counters, ensuring Falco Spara, Pactweaver never runs out of fuel.
