Falco Spara, Pactweaver + Sensei's Divining Top + Umori, the Collector + Oneirophage

Falco Spara, Pactweaver

Sensei's Divining Top

Umori, the Collector

Oneirophage

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. Oneirophage triggers, putting a +1/+1 counter on it.
3. Cast Sensei's Divining Top from the top of your library by paying 0 and removing a counter from a creature you control.
4. Repeat.

This clever loop turns your library's top card into a revolving door by leveraging Falco Spara, Pactweaver to cast spells from the top of your deck using counters instead of mana. Sensei's Divining Top anchors the combo, tapping to draw a card and instantly redepositing itself right back onto the top of your library where Falco can grab it again. Meanwhile, Umori, the Collector quietly reduces the artifact's cost to zero, allowing you to replay the Top for free by constantly stripping away the +1/+1 counters that Oneirophage rapidly accumulates with every single card you draw.
