Falco Spara, Pactweaver + Sensei's Divining Top + Uthros Research Craft + Sami, Wildcat Captain

Falco Spara, Pactweaver

Sensei's Divining Top

Uthros Research Craft

Sami, Wildcat Captain

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 Diving Top from the top of your library by paying 0 and removing a charge counter from Uthros Research Craft.
3. Uthros Research Craft triggers, putting a charge counter on it and causing you to draw a card.
4. Repeat.

This clever loop turns your library into an endless well of cards by using Sensei's Divining Top to repeatedly draw itself and glide back to the top. Falco Spara, Pactweaver is the catalyst that makes this possible, letting you bypass traditional mana costs by sacrificing counters instead—which allows you to cast Sensei's Divining Top for free by removing the charge counters accumulated on Uthros Research Craft. As you recast your artifacts, Uthros Research Craft rewards your engine with additional card draw and keeps the charge counters flowing, all while Sami, Wildcat Captain steps in to help reduce your casting costs with its affinity for artifacts.
