Falco Spara, Pactweaver + Sensei's Divining Top + Semblance Anvil + Oneirophage

Falco Spara, Pactweaver

Sensei's Divining Top

Semblance Anvil

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 delightful loop turns Sensei's Divining Top into a self-replenishing engine by leveraging Falco Spara, Pactweaver's static ability to cast spells straight from the top of your library using creature counters as payment. With Semblance Anvil having exiled an artifact to reduce the Top's casting cost by {2}, drawing the Top leaves its cost completely free at {0}, allowing you to continuously recast it from the top without ever running out of counters. As you endlessly cycle the Top, Oneirophage happily joins in on the fun, capitalizing on every single draw trigger to grow exponentially larger with a steady stream of +1/+1 counters.
