Falco Spara, Pactweaver + Sensei's Divining Top + Yotian Dissident + Urza, Lord Protector

Falco Spara, Pactweaver

Sensei's Divining Top

Yotian Dissident

Urza, Lord Protector

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 Divining Top from the top of your library by paying 0 and removing a counter from a creature you control.
3. When Sensei's Divining Top enters, Yotian Dissident triggers, putting a +1/+1 counter on Yotian Dissident.
4. Repeat.

This clever loop turns Sensei's Divining Top into an infinite engine by leveraging Falco Spara, Pactweaver's ability to cast spells from the top of your library using counters instead of mana. Since Urza, Lord Protector reduces the artifact's cost down to zero, you can recast it for free directly from the library without ever needing additional mana. Every time the artifact re-enters the battlefield, Yotian Dissident triggers to continually replenish your creature's counters, ensuring Falco Spara, Pactweaver always has a fresh resource to fuel the next repetition.
