Falco Spara, Pactweaver + Sensei's Divining Top + Arcbound Crusher + Enthusiastic Mechanaut

Falco Spara, Pactweaver

Sensei's Divining Top

Arcbound Crusher

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, Arcbound Crusher triggers, putting a +1/+1 counter on Arcbound Crusher.
4. Repeat.

This loop turns your library into an endless well of cards by leveraging Falco Spara, Pactweaver's ability to cast spells directly from the top of your deck using creature counters as an alternative cost. With Enthusiastic Mechanaut on the battlefield reducing costs, Sensei's Divining Top becomes free to cast, allowing you to draw it and immediately replay it from the top of your library over and over. As the Top continuously enters and leaves the battlefield, Arcbound Crusher happily grows into a colossal threat by feeding on every single artifact entry.
