Falco Spara, Pactweaver + Sensei's Divining Top + Starnheim Courser + Chasm Skulker

Falco Spara, Pactweaver

Sensei's Divining Top

Starnheim Courser

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 loop transforms Sensei's Divining Top into a self-replacing engine by leveraging Falco Spara, Pactweaver to cast it directly from the top of your library for free—with Starnheim Courser stepping in to reduce its mana cost from one to zero. As you repeatedly draw and recast the artifact, Chasm Skulker eagerly watches every card drawn to grow exponentially larger with +1/+1 counters, all while feeding its own counters back to Falco Spara as the fuel required to keep the top deckcasting cycle spinning.
