Falco Spara, Pactweaver + Sensei's Divining Top + Stone Calendar + Lorescale Coatl

Falco Spara, Pactweaver

Sensei's Divining Top

Stone Calendar

Lorescale Coatl

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. Lorescale Coatl 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 from the top of your library using any creature's counter as an alternative cost. Sensei's Divining Top naturally feeds this by drawing a card and placing itself right back on top of your library, while Stone Calendar quietly reduces that casting cost down to zero so you can recast the Top for free. Every single time you draw with the Top, Lorescale Coatl happily grows larger and larger from the repeated triggers, providing a steady stream of fresh +1/+1 counters to perpetually pay for Falco Spara, Pactweaver's alternate casting costs.
