Falco Spara, Pactweaver

Sensei's Divining Top

Ballad of the Black Flag

The Astonishing Ant-Man

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. The Astonishing Ant-Man 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 relies on Falco Spara, Pactweaver to let you cast Sensei's Divining Top directly off the top of your library by trading away a counter instead of paying mana. Whenever you tap Sensei's Divining Top to draw, The Astonishing Ant-Man happily swoops in to catch the trigger by growing with a +1/+1 counter, which conveniently provides the exact fuel Falco Spara, Pactweaver needs to keep casting it. Meanwhile, Ballad of the Black Flag sits back as a majestic Saga, though its historical chapters aren't even necessary to keep this perpetual card-drawing machine spinning.
