Falco Spara, Pactweaver + Sensei's Divining Top + Arcbound Crusher + Voyager Quickwelder

Falco Spara, Pactweaver

Sensei's Divining Top

Arcbound Crusher

Voyager Quickwelder

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 your library into a bottomless well by leaning heavily on Falco Spara, Pactweaver to let you cast Sensei's Divining Top directly off the top of your library for the cost of removing a counter from a creature, circumventing its usual mana price. To keep that counter engine running indefinitely, Arcbound Crusher steps in by perpetually collecting new +1/+1 counters every single time Sensei's Divining Top re-enters the battlefield as an artifact. Meanwhile, Voyager Quickwelder plays a quiet supporting role by shaving {1} off the cost of your artifact spells, making sure the sequence remains frictionless and self-sustaining. Tap Sensei's Divining Top to draw a card and slide it back onto your library, recast it for zero mana using Falco Spara, Pactweaver's alternate cost, and watch Arcbound Crusher grow as you cycle through your entire deck.
