Falco Spara, Pactweaver + Sensei's Divining Top + Voyager Quickwelder + Stark's Ingenuity

Falco Spara, Pactweaver

Sensei's Divining Top

Voyager Quickwelder

Stark's Ingenuity

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. Stark's Ingenuity triggers, putting a +1/+1 counter on the creature it's attached to
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 loop relies on turning Sensei's Divining Top into a self-sustaining draw engine by letting you repeatedly recast it directly from the top of your library. Falco Spara, Pactweaver provides the crucial alternative casting permission, allowing you to bypass mana costs by removing a counter from one of your creatures instead. Each time you draw the Top, Stark's Ingenuity triggers to replace that spent counter with a fresh +1/+1 counter on the enchanted creature. Meanwhile, Voyager Quickwelder reduces the cost of casting the Top to zero, ensuring this cycle can repeat indefinitely to generate massive storm counts and infinite card draw.
