Falco Spara, Pactweaver + Sensei's Divining Top + Arcbound Crusher + Urza, Lord Protector

Falco Spara, Pactweaver

Sensei's Divining Top

Arcbound Crusher

Urza, Lord Protector

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 brilliant loop transforms Sensei's Divining Top into a self-sustaining draw engine by letting you repeatedly draw it and cast it right back off the top of your library. This is made possible by Falco Spara, Pactweaver, which bypasses mana costs by letting you cast from the top of your library using counters instead, while Urza, Lord Protector helps reduce costs elsewhere in your strategy. Every time you cast the Top, Arcbound Crusher happily swoops in to trigger its modular ability, growing larger with a steady stream of +1/+1 counters as the artifacts continuously enter and leave the battlefield.
