Falco Spara, Pactweaver + Sensei's Divining Top + Yotian Dissident + Enthusiastic Mechanaut

Falco Spara, Pactweaver

Sensei's Divining Top

Yotian Dissident

Enthusiastic Mechanaut

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 elegant engine turns a simple top-deck manipulation tool into an endless fountain of resources by letting you bypass mana costs entirely. Sensei's Divining Top draws you a card while tucking itself away, and Enthusiastic Mechanaut makes it completely free to cast, while Falco Spara, Pactweaver allows you to play it right off the top of your library by consuming a counter from a creature. To sustain this loop, Yotian Dissident steps in with its passive triggered ability, placing a fresh +1/+1 counter back onto a creature every time the artifact enters the battlefield, neatly replacing the counter you just spent to keep the cycle spinning.
