Falco Spara, Pactweaver + Sensei's Divining Top + Herald of Kozilek + Captain Storm, Cosmium Raider

Falco Spara, Pactweaver

Sensei's Divining Top

Herald of Kozilek

Captain Storm, Cosmium Raider

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, Captain Storm triggers, putting a +1/+1 counter on Captain Storm.
4. Repeat.

This clever loop turns the iconic top-deck manipulation of Sensei's Divining Top into a self-sustaining engine by utilizing Falco Spara, Pactweaver's ability to cast spells directly from the top of your library using counters instead of mana. To make this costless, Herald of Kozilek steps in to reduce the colorless casting cost of Sensei's Divining Top down to zero, ensuring you never run out of resources. Meanwhile, Captain Storm, Cosmium Raider acts as the perfect catalyst, continually replacing the counters removed by Falco Spara by dropping a new +1/+1 counter onto itself every single time the artifact re-enters the battlefield.
