Falco Spara, Pactweaver + Sensei's Divining Top + Chasm Skulker + Stenn, Paranoid Partisan

Falco Spara, Pactweaver

Sensei's Divining Top

Chasm Skulker

Stenn, Paranoid Partisan

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 the top of your library into an endless engine by combining Sensei's Divining Top with Falco Spara, Pactweaver's ability to cast spells from the library using creature counters as alternative costs. To make this mana-neutral and sustainable, Stenn, Paranoid Partisan steps in to reduce the cost of the artifact to zero, allowing you to continually recast it without running out of resources. Meanwhile, Chasm Skulker feasts upon the endless card draw generated by the Top, growing massively with +1/+1 counters to leave behind a devastating army of Squids should it ever perish.
