Falco Spara, Pactweaver + Sensei's Divining Top + Arcbound Crusher + Cemetery Prowler

Falco Spara, Pactweaver

Sensei's Divining Top

Arcbound Crusher

Cemetery Prowler

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 clever loop turns Sensei's Divining Top into a self-replacing engine by exploiting Falco Spara, Pactweaver's ability to cast topdeck spells using creature counters as an alternate payment method. With Cemetery Prowler passively reducing the artifact's mana cost down to zero, you can continuously tap Sensei's Divining Top to draw a card and return it to the library, then immediately recast it from the top. Every iteration of this cycle feeds Arcbound Crusher with a fresh +1/+1 counter every time Sensei's Divining Top enters the battlefield, neatly replacing the counter you removed to fuel Falco Spara, Pactweaver's alternate casting cost.
