Falco Spara, Pactweaver + Sensei's Divining Top + Foundry Inspector + Chasm Skulker

Falco Spara, Pactweaver

Sensei's Divining Top

Foundry Inspector

Chasm Skulker

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. Chasm Skulker 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 your library into an endless engine by leveraging Falco Spara, Pactweaver's ability to cast spells straight from the top using counters as payment. With Foundry Inspector discounting artifacts to free, you can repeatedly tap Sensei's Divining Top to draw it and place it back on your library, then recast it immediately for zero mana by stripping a counter off Chasm Skulker or even Falco Spara itself. Every iteration of this cycle triggers Chasm Skulker to grow larger while cycling Sensei's Divining Top endlessly, netting you infinite card draw and storm count along the way.
