Falco Spara, Pactweaver + Sensei's Divining Top + Helm of Awakening + Chasm Skulker

Falco Spara, Pactweaver

Sensei's Divining Top

Helm of Awakening

Chasm Skulker

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. Chasm Skulker 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 crafty loop turns your library's top card into a self-sustaining engine by letting Sensei's Divining Top constantly draw itself and glide right back into position. Helm of Awakening plays a vital supporting role by discounting the artifact's mana cost down to zero, while Falco Spara, Pactweaver grants the alternative payment method needed to cast it from the top of your library by consuming counters instead of mana. Meanwhile, every iteration feeds Chasm Skulker's triggers, rapidly growing a massive army of squids in the wings.
