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

Falco Spara, Pactweaver

Sensei's Divining Top

Starnheim Courser

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 ingenious loop turns 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—using the shield counter it enters with as payment. Because Starnheim Courser reduces the artifact's mana cost down to zero, you can continuously draw the Top, recast it, and repeat the process indefinitely. As a delightful bonus, every iteration draws a card that triggers Oneirophage, rapidly growing its size while churning through your entire deck for infinite storm and artifact triggers.
