Falco Spara, Pactweaver + Sensei's Divining Top + Urza, Lord Protector + Mm'menon, Uthros Exile

Falco Spara, Pactweaver

Sensei's Divining Top

Urza, Lord Protector

Mm'menon, Uthros Exile

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, Mm'menon triggers, putting a +1/+1 counter on Mm'menon.
4. Repeat.

This loop turns Sensei's Divining Top into an endless fountain of card draw by leveraging Falco Spara, Pactweaver to cast it directly from the top of your library for free—thanks to Urza, Lord Protector reducing its mana cost to zero. Whenever Sensei's Divining Top enters the battlefield, Mm'menon, Uthros Exile triggers to replenish your creatures with a fresh +1/+1 counter, which Falco Spara, Pactweaver can immediately consume to pay the alternate cost for the next cast. By cycling the Top back and forth between your library and the battlefield, you can endlessly draw your deck while generating an infinite storm count and artifact entry triggers.
