Falco Spara, Pactweaver + Sensei's Divining Top + Chasm Skulker + Jhoira's Familiar

Falco Spara, Pactweaver

Sensei's Divining Top

Chasm Skulker

Jhoira's Familiar

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 clever engine turns Sensei's Divining Top into a self-casting loop by leveraging Falco Spara, Pactweaver's ability to cast spells from the top of your library using creature counters as an alternative cost. Because Sensei's Divining Top is a historic spell, Jhoira's Familiar reduces its mana cost down to zero, allowing you to continually tap the Top to draw it back to your library and recast it for free. Meanwhile, every card drawn triggers Chasm Skulker to pile up +1/+1 counters, growing your threat pool exponentially while generating an endless stream of artifact enters-the-battlefield and storm counts.
