Falco Spara, Pactweaver + Sensei's Divining Top + Uthros Research Craft + Kykar, Wind's Fury

Falco Spara, Pactweaver

Sensei's Divining Top

Uthros Research Craft

Kykar, Wind's Fury

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 1 and removing a charge counter from Uthros Research Craft.
3. Kykar and Uthros Research Craft trigger.
4. Resolve the Uthros Research Craft trigger, putting a charge counter on it and causing you to draw a card.
5. Resolve the Kykar trigger, creating a 1/1 Spirit creature token.
6. Activate Kykar by sacrificing the Spirit, adding .
7. Repeat.

This elegant loop turns Sensei's Divining Top into a self-sustaining engine by letting you repeatedly cast it from the top of your library. The primary enabler is Falco Spara, Pactweaver, whose static ability allows you to pay for spells from the top of your library by removing counters from your creatures, bypassing the Top's normal mana cost while feeding on the charge counters accumulated by Uthros Research Craft. Every time you cast the artifact, Uthros Research Craft triggers to draw you a card and replace its consumed counter, while Kykar, Wind's Fury pitches in by generating a Spirit token off the noncreature spellcast. Finally, sacrificing that Spirit to Kykar's mana ability provides the red mana needed to activate the Top's draw-and-reposition ability, keeping the loop spinning indefinitely.
