Falco Spara, Pactweaver + Sensei's Divining Top + Arcbound Crusher + Jhoira's Familiar

Falco Spara, Pactweaver

Sensei's Divining Top

Arcbound Crusher

Jhoira's Familiar

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 ingenious loop turns Sensei's Divining Top into a self-replacing engine by drawing itself and returning straight to the top of your library. Falco Spara, Pactweaver provides the vital alternative casting cost, letting you trade the counters on your creatures—including the ones generated when Arcbound Crusher grows from each artifact entering—to cast the Top for free. Meanwhile, Jhoira's Familiar steps in to reduce that casting cost, ensuring the loop runs smoothly without draining your mana.
