Falco Spara, Pactweaver

Sensei's Divining Top

Foundry Inspector

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 relies on Falco Spara, Pactweaver to fundamentally rewrite how you play your topdecks, letting you cast spells directly from the library by simply stripping a counter off a creature you control instead of paying their mana costs. Sensei's Divining Top naturally feeds this by drawing you a card and slipping right back onto the top of your library upon tapping, while Foundry Inspector steps in to completely wipe out the Top's casting cost, making it free to replay. Meanwhile, Lorescale Coatl watches the entire engine turn with delight, growing larger with a fresh +1/+1 counter every single time you draw a card from the Top's activation. Together, these pieces create a self-sustaining cycle that endlessly redraws your deck, pumps your snake bird to massive proportions, and piles up an astronomical storm count.
