Falco Spara, Pactweaver

Sensei's Divining Top

Foundry Inspector

Oneirophage

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. Oneirophage 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 elegant loop centers on Sensei's Divining Top, which naturally replaces itself by drawing a card and returning to the top of your library. Foundry Inspector steps in to slash the Top's casting cost down to zero, allowing you to replay it for free using Falco Spara, Pactweaver's ability to cast spells from the top of your library by removing a counter from a creature you control. Meanwhile, Oneirophage happily grows into a colossal threat with every iteration, turning a simple card-draw loop into massive stats alongside your endless triggers and storm count.
