Falco Spara, Pactweaver + Sensei's Divining Top + Cloud Key + Oneirophage

Falco Spara, Pactweaver

Sensei's Divining Top

Cloud Key

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 into an endless well of card draw by leveraging Falco Spara, Pactweaver's ability to cast spells from the top of your library using counters instead of mana. With Cloud Key naming artifacts, Sensei's Divining Top's mana cost is reduced to zero, allowing you to repeatedly tap the Top to draw itself and place it right back onto your library. Every time you draw a card, Oneirophage happily grows larger with a new +1/+1 counter while feeding you an endless chain of artifact triggers.
