Falco Spara, Pactweaver + Sensei's Divining Top + Surge Conductor + Jhoira's Familiar

Falco Spara, Pactweaver

Sensei's Divining Top

Surge Conductor

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. Cast Sensei's Diving Top from the top of your library by paying 0 and removing a counter from a creature you control.
3. When Sensei's Divining Top enters the battlefield, Surge Conductor triggers, putting a counter on a creature you control that already has a counter on it.
4. Repeat.

This delightful loop turns Sensei's Divining Top into a free, endlessly repeatable engine by leveraging Falco Spara, Pactweaver to cast artifacts right off the top of your library for the low cost of removing a creature's counter. To keep that cost from ever running dry, Surge Conductor steps in as a clever battery, proliferating a counter back onto your creatures every single time Sensei's Divining Top re-enters the battlefield. Meanwhile, Jhoira's Familiar eases the financial burden by making your historic artifacts completely free to cast.
