Falco Spara, Pactweaver + Sensei's Divining Top + Cemetery Prowler + Oneirophage

Falco Spara, Pactweaver

Sensei's Divining Top

Cemetery Prowler

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 repeatable engine by combining Sensei's Divining Top with Falco Spara, Pactweaver, which lets you cast spells from the top of your library simply by removing a counter from a creature you control. Cemetery Prowler works behind the scenes to reduce the cost of your artifacts down to zero, meaning you can recast the Top for free after drawing it. Meanwhile, every iteration pumps up Oneirophage with a +1/+1 counter each time you draw, letting you turn your endless card draw into a massive flying threat while generating an infinite storm count and artifact triggers.
