Falco Spara, Pactweaver + Sensei's Divining Top + Foundry Inspector + Captain Storm, Cosmium Raider

Falco Spara, Pactweaver

Sensei's Divining Top

Foundry Inspector

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 lets you draw your entire deck by repeatedly cycling Sensei's Divining Top right back to the top of your library and casting it for free. Foundry Inspector does the heavy lifting by reducing the artifact's mana cost down to zero, while Falco Spara, Pactweaver grants you the ability to cast it directly from the library by paying the remaining cost with a counter instead of mana. To keep that engine fueled indefinitely, Captain Storm, Cosmium Raider steps in to replace spent counters with fresh +1/+1 counters every time the Top enters the battlefield anew.
