Falco Spara, Pactweaver + Sensei's Divining Top + Umori, the Collector + Kappa Cannoneer

Falco Spara, Pactweaver

Sensei's Divining Top

Umori, the Collector

Kappa Cannoneer

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. Cast Sensei's Divining Top from the top of your library by paying 0 and removing a counter from a creature you control.
3. When Sensei's Divining Top enters, Kappa Cannoneer triggers, putting a +1/+1 counter on Kappa Cannoneer.
4. Repeat.

This loop transforms Sensei's Divining Top into a free, repeatable draw engine by leaning on Falco Spara, Pactweaver's unique ability to let you cast spells from the top of your library simply by paying a counter cost instead of mana. Because Sensei's Divining Top puts itself back on top of your library when its draw ability resolves, you can continuously recast it for free using Falco Spara, Pactweaver's cost-replacement effect—and Umori, the Collector can even help reduce other costs in your deck if needed. Every time you replay the artifact, Kappa Cannoneer triggers to pile up endless +1/+1 counters and make itself unblockable, letting you churn through your entire library while turning a simple top-deck manipulation tool into a game-winning threat.
